AI-Enabled, Automated Digital Dull Bit Analysis - The Future of Bit Wear Forensics

Category: Drilling & Completion

Objectives/Scope: IADC dull bit grading is the current industry standard to document the condition of a dull drill bit. However, since today’s methods rely on human interaction and judgement, the resulting data is limited in terms of its accuracy, its consistency, and its comparability. As a result, the usefulness of this data in improving how bits are designed and operated is also limited. This paper describes a system that overcomes these limitations by performing automated digital bit dull grade analysis, forensics, and analytics. Methods, Procedures, Process: The system described incorporates the automated generation of a digital three-dimensional model of a dull bit, which is then analyzed digitally to assess bit wear, as well as other bit dull grade characteristics, on an individual cutter basis, as well as on an overall bit basis. Since the process is automated and digital in nature, the uncertainties related to human interaction and judgement in the process typically used today are eliminated. This data can also be used to identify drilling dysfunctions, and modify drilling procedures accordingly, to optimize performance. Results, Observations, Conclusions: Examples of digital dull bit analyses will be shown, which demonstrate that the bit wear data obtained from the system is much more detailed, more accurate, more consistent, and more comparable than the methods employed today. The resulting data is also much more suited to analytics, as well as other types of analysis, with a view to modifying bit designs and/or operational parameters, as well as identifying drilling dysfunctions causing bit damage. Novel/Additive Information: Dull bit grading is one of the only area areas of modern drilling operations that has not yet been digitized. The system described in this paper remedies this by performing automated digital bit dull grade analysis, thereby eliminating the issues with human interaction and judgement in today's bit dull grading processes. It represents an important advance in how bit dull forensic information is gathered, analyzed and utilized.

Asphaltene Inspired Functional Organic Materials

Category: Clean Technology & Environmental Management

Near the end of the 1970s an important discovery was made by three scientists: Heeger, MacDiarmid, and Shirakawa. They found that materials composed of organic conjugated polymers were able to conduct electricity, a stark contrast to the typical electrically insulating properties of the plastic polymers used around the world, such as polyethylene or polypropylene. This discovery was important enough to not only garner the Nobel Prize in 2000, but also ushered in a new era of research on the newfound field of organic electronics. The field itself has advanced many important technologies such as solar cells, light emitting diodes (LEDs), transistors, sensors, and even batteries. All of which are powered by the underlying electrical conductivity of organic conjugated materials/polymers, which themselves share similarities to the proposed structures of the components of asphaltenes found in Alberta Oil and Gas production. Structurally, asphaltenes can be described as complex mixtures of organic molecules that bear resemblance to the conjugated organic frameworks commonly used in these organic electronics. Today, the field of organic electronics is as active as ever with thousands of researchers both in academia and industry working tirelessly on new discoveries leading to billions of current and potential market values. A key driving force in the activity of the field is the fact that these organic polymeric materials can form advanced technological devices through simple printing processes, much like ink to paper. Thus, rendering the technologies coming out of this research as very cheap, and due to the printing process, these materials also gain unique functional properties such as flexibility, stretchability, and transparency. At the University of Calgary, the Functional Materials and Advanced Coating Laboratory has been pioneering novel syntheses and processing methods for conjugated organic materials/polymers and demonstrating their uses for nearly a decade. Emerging from our group, and adopting from others, have come novel methods for processing these conjugated organic materials into functional inks, films, nanoparticles, and crystals as well as new synthesis pathways for extending conjugation in the materials through the formation of covalent bonds. This presentation will cover the ways in which these state-of-the-art methodologies can be applied to asphaltenes to develop new conjugated organic materials, and how we can design new materials which are either inspired by and/or utilize the components found within asphaltenes. Overall, the aim of our project is to find and develop new applications for one of Alberta’s most prolific natural resources.

Automating Liquid & NGL Leak Detection at Above-Ground Facilities Using AI-Powered Imaging

Category: Clean Technology & Environmental Management

In the oil and gas industry, it is critical to stop leaks before they impact asset safety, business operations, the community, and the environment. Response times, however, are dependent upon the time it takes to detect and confirm a leak. Sufficiently monitoring upstream and midstream facilities that are partially manned or remote (e.g.: pump stations, pig trap stations, block valve sites and onshore and offshore well pads) have been economically challenging using traditional methods. Currently adopted technologies and processes (CPM, acoustic, sniffers, manned surveillance) do not provide the high level of confidence needed to take immediate action, requiring personnel to verify alarms by traveling to the potentially hazardous site.

The poster presentation will offer insight into the current challenges of monitoring remote assets and how they influence response times, and introduce a better and cost-effective modern alternative. Learn how fixed thermal imaging combined with real-time artificial intelligence and deep machine learning technologies provides an effective solution for automating leak detection and reporting.

Analytic thermal imaging is a relatively new, non-traditional fluid leak detection method adopted in the middle of the last decade by major oil and gas operators in North America. The edge-based technology is being used to continuously and autonomously monitor facilities of major oil and gas operators in North America and the Gulf of Thailand, and has over 350,000 of field hours. The system looks for a temperature change in the scene and analyzes leak characteristics in real time using patented and proprietary image processing software, and generates alerts (with photo and video) for validated events. Leaks of 1L/s and lower can be detected and alarmed on in less than 30 seconds, and visually verified remotely within a minute.

Due to low false alarm rates, operators can easily manage this additional solution without requiring additional resources. There are other advantages of using the system. These include the incorporation of a fixed low-cost color camera for routine visual checks, reducing site visits and manpower, low bandwidth consumption from only transmitting alarms rather than continuous raw data, integrating security/intrusion analytics, and distributed assets monitoring.

AI-powered imaging delivers reliable round-the-clock leak detection and asset surveillance across a wide range of applications. This solution supplements existing external sensing technologies and improves asset operational management capabilities through speed. This technology solution aligns with the industry best practice of layering multiple methods to achieve a more comprehensive and robust coverage.

The Benefits of Direct Contact Steam Generation for Enhance Oil Recovery

Category: Cleaner Hydrocarbon Production & Enhanced Oil Recovery

Direct Contact Steam Generation (DCSG) that injects both steam and hot combustion flue or exhaust gases into the reservoir, has the potential to greatly improve the Steam-Oil-Ratio (SOR) for increased oil recovery as well as delivering environmental benefits related to reduced water and emissions. Reservoir production is increased by reducing oil viscosity through heat, repressuring the reservoir with the combustion gases and potentially improving miscibility with the CO2 that remains in the reservoir. GERI’s portable DCSG system was initially piloted in post-CHOPS wells in the Lloydminster area in partnership with oil operators. Each pilot test included at least one steam and production cycle. For two pilots, a reservoir model was first developed to assess the feasibility and approach for injection and production. A multi-well CHOPS model integrated with CMG STARS simulator was used to forecast reservoir performance by history matching the oil, water and sand production data for the selected test well and several surrounding wells. The initial test was a huff pull cycle followed by a second injection cycle. To date over 18,000 barrels of incremental oil production has been realized from the test and offset wells resulting in a combined SOR of less than 0.6 compared to a typical industry SOR of 3.0. Furthermore, the field trials were able to quantify the environmental benefits of DCSG as 50% less emissions with at least 70% of the CO2 sequestered. Based on the results of the pilots, a DCSG that injects both steam and hot combustion exhaust gases into the reservoir can be effective in other enhanced oil recovery applications. Steam Assisted Gravity Drainage (SAGD) applications include using the flue gas to re-pressurize late stage reservoir, potentially mitigating “thief zones or in combination with infill wells to connect separate heated pools. For tight oil or low permeability reservoirs, DCSG can provide energy and re-pressurize the reservoirs, but also introduce a sweep effect, thereby, increasing recovery. Although the heat impact introduced by steam may not be as great as it is on heavy oil reservoirs, it can reduce oil viscosity and increase oil mobility. A history matched multi-well reservoir model was developed on a tight and lighter reservoir, with an oil density of 20 API and average permeability of 40 md to assess the feasibility of DCSG. Simulation results showed that even with a short injection period (15 - 40 days) of steam plus flue gases, incremental oil recovery for the first year could be 3 to 4 times compared to the no-injection scenario. A portable DCSG solution allows for inexpensive, short term pilots to confirm the opportunity.

Demonstration Project Reduces Energy Consumption by 35% for Horizontal Wells

Category: Cleaner Hydrocarbon Production & Enhanced Oil Recovery

Oil producers typically install VFD controllers with high efficiency Nema B motors on new horizontal wells in an attempt to reduce the energy intensity of reciprocating artificial lift. This combination usually provides a 20% improvement in energy cost over the use of Nema D motors. Unfortunately, for existing wells this reduction in cost is not enough to generate the payback horizon required for replacing the existing Nema D motors with VFD controllers coupled with high efficiency Nema B motors. Additionally, attempts to use more expensive regenerative units increases capital costs which cancels out the added energy savings leaving producers with no option forward for existing wells. In contrast to this traditional approach, our modeling indicated that it should be possible to achieve more than a 30% reduction in energy costs through the use of more advanced control methods for a VFD coupled with an existing Nema D motor. To validate our modeling, we partnered with an oil producer and Alberta Innovates to demonstrate energy intensity reduction on a large number of wells in real-field conditions over a year-long period. The goal was to demonstrate a viable path to permanent reduction in operating cost and energy intensity for existing oil production and make investing in energy intensity and lifting cost reduction more appealing. We will present results from our product demonstration field trial in South-East Saskatchewan that was initiated in the fall of 2020. We installed our advanced IIoT automation VFD controllers and coupled them with existing Nema D motors on 24 wellsites, collected power consumption and productivity data for each well before and documented power consumption and well productivity post installation. 12 months of data from this demonstration, including cost analysis, energy reduction results, and methodology demonstrates that our proprietary VFD control technology coupled with our machine learning analytics minimizes lifetime energy intensity by over 35% creating a strong financial incentive for oil producers to invest in energy intensity reduction.

From Organic Building Blocks to Highly Coordinated Nanoporous Materials: On The Dehydration of a Metal-Organic Frameworks for CO2 Capture

Category: Clean Technology & Environmental Management

The molecular design of tailored porous materials give potential for a variety of applications, [1] including chemical separations, [2] gas, [3] liquid, [4] and energy storage, [5] or chemical sensing. [6] The design of new porous materials that are stable in water and acidic environment is primordial since most of them degrade in such conditions. In this regard, metal-organic framework (MOF), is a class of porous material that forms from the self-assembly of metal and organic linkers. [7] The MOFs are good candidates for the capture of CO2 gases since they have large surface areas, and the metal or linker can be tuned to improve the CO2 uptake. In the quest for water and acid-stable MOFs, two porous materials have been designed. The first network, called HCALF-37, was prepared using a phosphonate-based organic linker, ionic calcium nodes, water, and methanol molecules to create a hydrogen bond assisted porous network (HMOF). This network is robust and can maintain its pore shape even in absence of water or methanol molecules or by the inclusion of gas molecules, such as CO2. Indeed, the network can be heated to release the water and methanol molecules and form a dehydrated MOF, which retains its shape with the imprinted pore within. By combining another phosphonate-based organic linker with hexaaquachromium(III) metal nodes, the water molecules ligated to the chromium (III) node create the coordination bonds between the metal and the linkers and a charge-assisted hydrogen-bonded porous network is formed, i.e., HCALF-50. [8]. This network is more dynamic than HCALF-37, and can be shaped by the inclusion of template molecules, such as xylene. The experiments revealed that the network can be heated to release the water molecules and form a dehydrated MOF (CALF-50). Then, the subsequent removal of template molecules allows the MOF to retain its shape with the imprinted pore within. On the other hand, in the absence of template molecules during the dehydration, the dehydrated network collapse as an amorphous solid. In this work, we perform molecular dynamics (MD) simulations in order to provide insight into the role of water and template molecules in directing network topologies and promoting porosity. We model the dehydration of the HMOFs in the absence and in presence of template molecules (bare and templated HMOF, respectively), by progressively withdrawing water molecules from the networks. We determine the crystal structure of the intermediate states from HMOF to MOF to shed light on the critical impact of the water molecules on the mediation of the bonds between the metal and the linkers. Our calculations reveal that the dehydration of the bare HCALF-50 leads to the precipitation of the network into an amorphous structure, in agreement with the experimental observation. The simulation of CO2 diffusion in HCALF-50 showed that this network is not suitable for CO2 capture as seen by the erratic movement of the CO2 all over the MOF in the completely dehydrated state. The xylene molecules allowed the dehydrated CALF-50, which is inherently amorphous, to maintain its configuration. By contrast, the diffusion of CO2 is inhibited in the stable HCALF-37 network, indicating its ability to efficiently sequester CO2 within the pores. This study showed that HCALF-50 would not be a suitable candidate for CO2 capture, whereas HCALF-37 would be a potential candidate in this respect. This work also points out the dynamical aspects of the dehydration mechanism and the key impact of template molecules on the stability of the networks. This research was undertaken in part thanks to funding from the Canada First Research Excellence Fund program.

How to Prevent Insoluble Dithiazine Solids Utilizing Triazine-Free Hydrogen Sulfide Scavengers

Category: Cleaner Hydrocarbon Production & Enhanced Oil Recovery

Energy efficiency, net-zero, de-carbonation of the Oil & Gas industry has made it to the top list of initiatives since the start of the pandemic. As Hydrogen Sulfide (H₂S) continues to increase in oil and gas production, operators are now faced with reliability challenges as a side-effect with traditional triazine based H₂S scavenger applications. Triazene-free scavengers are on the verge of an industry wide solution. Over the last 20 years triazine based H₂S scavengers have predominately been used to reduce H₂S concentrations in production applications. Without proven economic alternatives, the use of highly toxic triazine scavengers has evolved into a global industry practice for H₂S management. Triazines are created by reacting formaldehyde and monoethanolamine (MEA). The result is a mixture of water and triazine, and possibly with some unreacted formaldehyde. When used for H₂S management, triazine scavengers create insoluble dithiazine solids as a by-product when reacting with H₂S molecules. Previous research has demonstrated that dithiazine causes scaling and corrosion on processing equipment and deposits within gas systems. Additives, including methanol, are used to keep dithiazine in solution to prevent adverse effects. In dry gas systems, the gas is found to evaporate the methanol, resulting in concentrated dithiazine deposits, which can cause blockages. Over the last decade, new chemistry has been developed, tested, and trialed for safe-replacement Triazine-free H₂S scavenger technology. The proprietary chemistry irreversibly reacts with H₂S to creating water-soluble salts. Previous research and lab tests demonstrate that the trace amounts of salt generated naturally mix with liquids and gas precipitate and do not result in corrosion or deposits. As a result, by-product treatment and downstream retrieval are not required. Supported by four patents, tests validate that the developed chemistry results in considerable cost saving for H₂S management compared to triazine scavengers. The scavenger solution is non-regulated, safe-to-handle, biodegradable, near odourless, and has a low toxicity with no flashpoint. The chemistry's unique properties allow the scavenger to be blended for various winter or summer applications. Tests have concluded that the chemistry remains effective after freeze-thawing, does not react with CO2, and will not foam from agitation. Proven as commercially viable chemistry by lab and field tests, the scavenger is undergoing trials by leading operators in sour water systems as a direct-replacement technology using existing injection equipment. With initial field trial results expected by mid-2021, the chemistry will continue to be field trialed in various oil and gas applications. As Triazene-free H₂S scavenger technology continues to be trialed and adopted, the energy industry can unlock widespread benefits, including reduced chemical and maintenance costs, improved reliability, and the elimination of scavenger safety and environmental hazards.

Integrated Planning and Construction Methodology for Energy Projects

Category: Pipeline & Processing Facilities

Although there is an effort to implement the best project management practices worldwide, energy projects, regardless of size, complexity, or industry, still experience difficulties meeting the three successful criteria. These criteria are: delivered on time, with a final actual cost on or below budget, and in full compliance with the technical and regulatory requirements. Energy projects are capital intensive, risky, and complicated endeavor. The larger the energy project, the greater the percentage of cost overrun and schedule slippage. It is imperative to reverse this trend to maintain a competitive edge in the energy sector. Two of the primary reasons why energy projects still experience difficulties to be successful are as follows. Firstly, the planning and construction phases are performed in a non-integrated way, where information is segregated into multiple systems, adding complexity to the challenging project environment. Secondly, the current practice to determine the project status during construction, using the activity percent complete technique, is an indirect and subjective method to determine progress. During the construction phase, project and construction managers are left tracking thousands of activities and tasks from multiple different contractors, and lose sight of the bigger picture. With an integrated approach, the planning phase's modeling starts with defining the scope of work - with a results-based work breakdown structure, a work plan schedule, and a cost estimate based on project results defined as deliverables and work packages. During the construction phase, project performance is measured using earned value and earned schedule. Earned value is credited as deliverables and work packages are completed using the binary theory. This theory is a simplified approach to credit value only for the physical work completed, increasing objectivity to determine the project percent complete and forecast final cost and completion date when closing each measurement reporting period during construction. Combining this result-oriented concept with a simplified application of earned value and earned schedule facilitates the planning and construction phases. It also increases the probability of success because projects are handled more objectively and proactively, based on performance. Besides, the integration with the financial system (invoicing) allows for tracking profit margins by deliverables. This methodology also enables monitoring programs and portfolios more effectively due to the consistency in recording productivity and efficiency indices (CPI and SPI, respectively), project percent complete, and forecasts of final cost and completion date. This integrated planning and construction methodology was developed to encourage private companies and government organizations to introduce changes in the way construction projects are handled nowadays to track margins, improve performance, and increase profits. The main challenge is to overcome current common practices during the planning and construction phases of energy projects.

A Practical Approach To Achieving Environmental Goals Through Your Electrical Equipment

Category: Pipeline & Processing Facilities

Oil & Gas companies face mounting pressure from all sides to achieve net-zero greenhouse gas emissions. Solving this problem does not have to be as costly as you may think. In fact, there are practical steps that can be taken with the electrical system that will realize reduced Scope 1 and Scope 2 greenhouse gas emissions while at the same time offer sizeable returns on investment to the operator. Electric motors are the workhorses in a pipeline and processing facility. Applying medium voltage (MV) adjustable speed drives (ASDs) for flow control and energy savings have been well understood and documented for decades. This savings in turn reduces the electric demand and therefor the carbon footprint associated with the generation of that demand. Another less understood method of reducing greenhouse gas emission is using ASDs for power factor improvement. By improving power factor the operating will see a corresponding electric bill savings and reduce even further the carbon footprint associated with power generation.. While ASD has historically been used to impact the bill's energy component, it's only recently that ASDs gained capabilities to influence the power factor. This is a powerful capability that makes a case for applying drives very compelling. Finally, MV drives that are treated with special enclosures eliminate the need for HVAC and thereby eliminate the energy consumption arising from the operation of the HVAC and the corresponding emissions to maintain the built environment around the VFD. In this presentation, we give an overview of the several practical solutions that MV drives can bring to overall sustainability of operations. The risks of not thinking about large VFDs as a strategic piece of equipment to reduce carbon emissions and electric costs in an environment of climate change pressures have become too large to ignore.

Supporting Pipeline Integrity and Planning through Collaboration and Data Capture

Category: Pipeline & Processing Facilities

Millions of kilometres of pipelines traverse thousands of municipal jurisdictions throughout North America. These pipelines and their related facilities are located in many different contexts, from sparsely populated rural areas to high-density urban centres, but are primarily on lands not owned by the operator. While pipelines are generally underground and therefore “out of site, out of mind” to most, challenges and conflicts can arise as a result of new development in proximity to or crossing these pipelines. Many municipal jurisdictions, landowners, and developers are not fully aware of the obligations related to developing in proximity to pipeline infrastructure ? it can oftentimes be an afterthought. If a plan has already been prepared and approved without adequately considering these matters, last-minute delays, additional costs, and frustrations can occur amongst both the municipal regulator, project proponent, and pipeline operator. Early engagement, awareness, and collaboration are key to mitigating these issues and are mutually beneficial for all stakeholders, including landowners, developers, municipalities, other government agencies, and pipeline operators. B&A has created an innovative land use planning and development monitoring program which has assisted pipeline operators and municipalities with collaborative planning in proximity to pipelines since 2016. Developed in conjunction with some of Canada’s major pipeline operators, this program has been refined and automated to facilitate early awareness of land use planning and development in proximity to pipeline systems and to support collaboration between pipeline operators and development stakeholders. Key program components and processes include: • Jurisdictional and stakeholder inventories; • Stakeholder outreach and communications; • Intake and analysis of land use planning, subdivision, and development application notifications; • Spatial referencing and mapping of notification boundaries in relation to pipeline infrastructure, viewable on an interactive web map; • Analysis and data collection summarizing impacts of notification on/from pipeline infrastructure, which can be tied to spatial boundaries; • Circulation and engagement with operator SMEs to facilitate a technical review; • Distribution of response to a municipal jurisdiction and/or development stakeholder detailing recommendations and requirements specific to their application; • Analysis of data collected over time to identify program effectiveness and trends in development patterns in the proximity of pipeline infrastructure. At the heart of this program are data and information sharing. The program has been developed to share information in an efficient manner while collecting data that can support decision-making in the long term. B&A’s poster and/or presentation will outline our program and its merits, including how it has helped pipeline operators meet regulatory obligations and be more proactive in managing risk.

Thermal Energy Storage: Path to Decentralizing Our Grid

Category: Sustainable Electricity Generation and Grid Modernization

SAIT’s Green Building Technologies (GBT) research group has partnered with Home Completions, Scout Energy, ATCO, and Sunamp to demonstrate and adapt the Sunamp Thermal Energy Storage batteries for North America, and run a series of simulated scenarios for use in Canada’s cold-climate residential sector in the GBT lab on SAIT campus. Using the Phase Change Material (PCM) based Thermal Energy Storage (TES) battery appliance, we will be running simulations for specific residential/commercial scenarios to demonstrate the integrated performance with micro Combined Heat and Power (mCHP), Solar Thermal, and Solar PV technologies with application for cold-climate. GBT lab will integrate the TES appliance first with the mCHP unit to study the combined performance of these appliances and produce data to support their usage in Demand-Side Management (DSM), and second with Solar Thermal and Solar PV to study the TES units’ applicability to arbitrage thermal heat from the Solar Thermal system, and also to convert electricity generated from Solar PV into thermal heat and use during low Solar Thermal and Solar PV production hours (cloudy, night time). Along with studying the combined performance of these integrated technologies, we will be collecting data pertaining to the applicability of DSM. This will include data that shows the amount of time needed between a call for a heat source, the availability of heat and electricity sinks during typical times needed for DSM, and studying the scalability and practical use cases for DSM with these technologies. A series of scenarios will be designed and executed to mimic residential and commercial thermal and electrical demands (and supply) at the GBT lab using the existing controls infrastructure. With the help of SAIT students, the scenario designs will be translated into programs to be run for a set period of time and under the conditions outlined. Data is collected and stored in a SQL data warehouse, where it will be pulled for analysis. Sensors are used to gather thermal and electrical exchange throughout the system, and to calculate overall performance with standard household and commercial appliance data as the benchmark. The BMS will be used to operate the on/off and run-level of the mCHP, domestic water “consumption”, thermal fluid transfer between appliances, and transfer to end-use loads. With the project still underway, we expect to see a greater utilization of the thermal byproduct from the mCHPs that will enable them to be a more practical option for Canadian households and commercial buildings. In comparison to benchmark data, GHG and energy advantages will be reported. Further to our studies with mCHP, Solar Thermal, and Solar PV, we expect TES technology to be a reliable thermal and electricity sink for surplus thermal and electrical energy generated from alternative energy resources.

Utilization of HCALF-50 for CO2 Capture

Category: Clean Technology & Environmental Management

Humans have been increasingly reliant on fossil fuels as a source of energy, for development, and for meeting higher standards of living. Unfortunately, the combustion of fossil fuels releases carbon dioxide (CO2) and methane (CH4) into the atmosphere, which not only trap the sun’s energy resulting in an increase in global temperature, but has also resulted in an atmospheric CO2 concentration of 415 ppm in 2020. Different technologies have been implemented to combat this, such as membrane capture, biological capture, cryogenic capture, liquid amines, chemical and calcium looping. An alternative to this are sorbent materials, of which Metal Organic Frameworks (MOFs) is a subclass. MOFs have a large surface area and tunable topology, formed using metal ions and organic linkers. They have been shown to be very versatile and promising candidates for gas storage, separation, heterogeneous catalysis, sensing, and luminescence. The ability to control the pore size, shape and the chemical potentials of adsorbing surfaces results in the ability to control the selectivity, kinetics and capacities of the MOFs, to suit the capture of CO2. The objective of this study was to explore the utilization of HCALF-50 for CO2 capture by studying the effect of the change in temperature, hydration/dehydration, annealing and template molecules on the MOF. HCALF-50 was synthesized by combining a phosphonate-based organic linker with hexaaquachromium(III) metal nodes where a charge-assisted hydrogen bonded porous network is formed as a result of water molecules ligating to the chromium(III) nodes. In this study we performed Molecular Dynamics (MD) simulations utilizing GROMACS and Packmol, in a 2 x 2 x 2 cell of HCALF-50. We analyzed the effect of temperature on the crystal structure of the MOFs, the slow dehydration of HCALF-50 to examine the impact of water on the bonds between the metals and linkers; modelling the effect on the crystal structure of the MOFs due to xylene template molecules in the completely hydrated (HCALF-50) and completely dehydrated (CALF-50) MOFs; and the capture of CO2 in both HCALF-50 and CALF-50. Results indicate that the volume of the dehydrated HCALF-50 decreased as the temperature increased, and as the MOF was slowly dehydrated, as a result of the amorphous nature of the MOF, as supported by previous literature. The xylene molecules allowed the dehydrated HCALF-50, which is inherently amorphous, to maintain its configuration. The calculations with CO2 showed that the HCALF-50 is not suitable for CO2 capture as seen by the erratic movement of the CO2 in CALF-50. In conclusion, HCALF-50 was found to not be a good candidate for CO2 capture due to the amorphous nature of the MOF, and lack of stability of CO2 in CALF-50. We also showed the impact of template molecules on the stability of the MOF.
