CO2 flooding is a favorable technical means for the efficient development of low-permeability reservoirs, and it can also contribute to realization net-zero emissions. However, due unfavorable viscosity ratio gravity overriding effect, channeling will inevitably occur, seriously affecting its storage displacement effects. This paper conducts systematic study on application polymer-assisted in r...

Cost estimates for CO2 capture and storage (CCS) systems typically focus on details of the CO2 capture process and make simplistic assumptions about the cost per ton of CO2 for the transport and storage components of the system. These ad hoc assumptions ignore the large variability in the storage cost from site-to-site caused by variation in storage reservoir characteristics. Moreover, the typi...

Increasing level of carbon dioxide CO2 due to industrial activity is primarily cause of global warming. Planting Artoplex lentiformis can help to reduce atmospheric CO2 buildup partly replacing use of fuels and by carbon storage. The objective of this study was to determine the effects of row spacing on carbon storage. A split- plot design with three replications included three row spacing (2×2...

Farnsworth Field Unit (FWU), a mature oilfield currently undergoing CO2-enhanced oil recovery (EOR) in the northeastern Texas panhandle, is study area for an extensive project undertaken by Southwest Regional Partnership on Carbon Sequestration (SWP). SWP characterizing field and monitoring modeling injection fluid flow processes with intent of verifying storage CO2 timeframe 100–1000 years. Co...

Dimethyl ether (DME) is a compound first introduced by Shell as chemical solvent for enhanced oil recovery (EOR). This study aims to investigate the efficiency of EOR using minimum miscible pressure (MMP) and viscous gravity number when mixed CO2 DME injected. Adding water-alternating-gas process reduces MMP number. Reduction in results conditions at lower pressures, which has favorable effect ...

The North Burbank Unit, located in Osage County, was originally discovered in 1920. It has an extensive history of activity, including primary depletion, produced gas cycling, and water and polymer flooding to the point of very high water cut at current conditions. The current oil production rate in the North Burbank Unit is approximately 1,400 BOPD from 360 active wells at a water cut of 99.5%...

Injecting CO 2 into hydrocarbon reservoirs can enhance the recovery of resources, and simultaneously, be stored in reservoirs, reducing considerable amount carbon emissions atmosphere. However, injected tends to go through fractures, high-permeability channels streaks present resulting inefficient coupled with low storage performance. Conformance treatments -resistant crosslinked polymer gels w...

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. and storage (CCS) is preferred over carbon conversion utilization (CCU) due its lower operating costs higher CO2 reduction capability. Nevertheless, has the be more economical if value-added products are produced. This highlights importance of assessing routes alternatives in management. rev...

Identifying and quantifying electrocatalytic-reaction-generated solution species, be they reaction intermediates or products, are highly desirable in terms of understanding the associated reaction mechanisms. We report herein a straightforward implementation of in situ solution electrochemical (13)C NMR spectroscopy for the first time that enables in situ studies of reactions on commercial fuel...
