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 ...

Efforts to mitigate the effects of climate change have led research and industry groups to explore ways of applying existing technologies and practices to the challenge of reducing CO2 emissions. The storage of CO2 in underground geologic reservoirs is one such idea that employs techniques developed for oil and gas production and transmission. For example, CO2 has been injected into petroleum r...

The presence of microorganisms could alter the porous medium permeability, which is vital for several applications, including aquifer storage and recovery (ASR), enhanced oil (EOR) underground hydrogen storage.

Abstract Hydrocarbons continue to play an important role in providing affordable energy meet rising demand. Amidst growing concerns on the environmental impact of oil and gas production processes, many researchers are increasingly exploring environmentally sustainable methods extracting hydrocarbons from reservoir. The introduction direct current into pore space activates mechanisms that enhanc...

Enhanced oil recovery (EOR) from shale formations is recognized as the next frontier in exploitation of unconventional resources. Current approaches for performing EOR experiments using fractured rocks can generate misleading results cores cannot be saturated with live oils. In this work, a novel laboratory methodology developed to quantify efficiency gas huff-n-puff under realistic reservoir c...

As the important role of enhanced oil recovery (EOR) in meeting world’s energy requirement is growing, use nanoparticles lieu of, or combination with, existing EOR agents to expand EOR’s applicable range receiving significant attention. Two most actively investigated applications are: 1) wettability alteration by addition into waterflood injection water, and 2) nanoparticle-stabilized Pickering...

Carbonated produced water injection (CPWI) might be considered an efficient alternative to handle the largest waste stream while enhancing oil recovery and storing carbon dioxide (CO2) underground. This study was attempt get a deeper understanding of process through synergy between spontaneous imbibition isothermal titration calorimetry (ITC) experiments. The results from experiments showed 7% ...
