... Abstract A potential solution to mitigate greenhouse gas emissions during hydrocarbon recovery is to employ cyclic CO 2 injection or ‘huff-n-puff (HnP) in multi-fractured horizontal wells completed in unconventional reservoirs. This serves to simultaneously reduce CO 2 emissions and increase...

... Abstract Continued fossil fuel use significantly increases greenhouse gas emissions, particularly CO 2 , prompting active scientific efforts to mitigate this interference with the climate system. One prominent approach is Carbon Capture and Sequestration (CCS), which involves a comprehensive...
