...Introduction Malaysia's pursuit of gas development presents a pressing challenge, while it holds the potential to meet the nation's growing energy demands, it also entails a significant increase in CO 2 emissions, addressing this dilemma is imperative, given global efforts to curtail CO 2...

... of 10% would also affect IFT when using two other types of cushion gas: CO 2 and N 2 . The contribution of this study is to provide IFT expressions for pore water with various gas mixtures involving CH 4 , H 2 , and H 2 S species under different pressure and temperature conditions for hydrogen storage...

..., there is currently no precedent of commercial development. After being injected into formations, CO 2 adsorbs onto the surface of clay minerals and causes the expansion of the rock matrix. Meanwhile, it reacts with water to produce carbonic acid to partially dissolve carbonate and silicate minerals in shale...

... concentration as the primary factors under investigation. These key parameters were identified as pivotal in understanding and resolving the challenges associated with the CO 2 off-specification issue in the gas processing plant. Tertiary amines and carbon dioxide react to form bicarbonate in MDEA-based...

... implementations due to limited information especially on long term wellbore integrity. This paper aims to offer insights and provide a comparative analysis on how cementing designs being the key to wellbore integrity and long-term zonal isolation will be affected when exposed to carbon dioxide (CO 2 ). Extensive...

... the open flow boundary. The average dip is 0.8 degree, and the initial free water level (FWL) was set to be 280 ft below the reservoir top at the producer location. The producer was placed in the reservoir up-dip at (I, J) = (18, 49) and completed for the top five (5) layers. On the other hand, the CO 2...

..., simulations were conducted by coupling reservoir simulations to analyze seabed displacement due to CO 2 injection. The results were compared with pressure distributions and the spread of the CO 2 plume, leading to discussions on their interrelationships. Reservoir model. Abstract This study...

... Abstract Surveillance data was acquired in four Gorgon CO 2 injection wells using Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) technology. The primary objective was to acquire temperature warmback data to quantify the CO 2 injection profile and demonstrate...

... Abstract CO 2 stimulation is a production stimulation technology that utilizes the expansion, extraction, and dissolution of CO 2 to replenish formation energy, increase recovery, increase oil well production in high water-cut heavy oil and bottom water reservoirs. It is also an excellent...

... Abstract Rapid screening and optimization of CO 2 enhanced oil recovery (EOR) process in unconventional reservoirs is urgently needed but challenging due to the complexity of this process and poor understanding of seepage in multiscale porous media. To address this issue, an interpretable...

... Abstract CO 2 fracturing and flooding have become key technologies for increasing shale oil recovery. However, for shale reservoirs with high wax content, the production data from Daqing oilfield indicate lower later-stage recovery rates and a significant occurrence of wax deposition during...

... Abstract The work comprises the set of lab corefloods of the displacement of water by CO 2 from sandstone cores. Previous experimental studies investigated the effects of water evaporation, Rock Dry-out, viscous fingering and Fines Migration with respect to permeability damage during CO 2...

The results were compared and evaluated to help assess how variation in parameters affect...

... Abstract Carbon capture and storage (CCS) technology is a crucial means to address global climate change and reduce atmospheric CO 2 . CO 2 mineralization storage can store CO 2 in underground rock formations in a long-term and safe manner, which is the most stable storage method. However...

... Abstract Coal exhibits a selective sorption mechanism, making it a potential natural filtration system for gas purification. This study explores the use of coal seam gas reservoirs for the simultaneous separation and storage of carbon dioxide (CO 2 ) from a mixture of hydrogen (H 2 ) and CO 2...

... Abstract Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. The objective of any carbon sequestration project is to store CO 2 safely for hundreds or thousands of years with a goal of mitigating global climate change. Based on literature, geochemistry...

... Abstract Capturing and converting CO 2 into value-added chemicals and materials is of great interest for decarbonization. Among them, the CO 2 conversion to advanced materials such as carbon nanotubes (CNTs) is a promising CO 2 utilization. CNTs can be used in many applications, owing to its...

... This study investigates an integrated carbon capture, transmission, and storage system. The analysis begins at the inlet of the process system whereby the captured CO 2 undergoes compression and dehydration to bring the CO 2 fluid to conditions optimal for pipeline transport. From...

... Figure 3 illustrates a situation where two CCS projects are injecting in licences A and C, with Licence B in-between them. The CO 2 plumes have not extended outside their blocks, but the pressure plume has extended and already began to increase the pressure in Licence B. A "pressure plume" can...

... Abstract Geological storage of carbon dioxide (CO 2 ) in the brine aquifer is a dual-benefit strategy for mitigating greenhouse gases and advancing carbon capture and storage (CCS). Meanwhile, the gas-water relative permeability (RP) of CO 2 and brine provides fundamental insights into flow...
