To address the unresolved mechanisms and debated microscale interactions governing crude oil desorption during low-salinity waterflooding in tight oil reservoirs, this study focuses on molecular-level interactions within the waterflooding process. Using molecular dynamics (MD) simulations, we constructed a multicompone...

Foam-assisted oxygen-reduced air injection (ORAI) tests were initiated to address critical challenges encountered in the Jiyuan Oilfield within Ordos Basin’s tight reservoirs: pervasive micro-fractures; rapid water breakthrough along dominant fracture planes impairing volumetric sweep efficiency during water flooding;...

To address challenges in the Jiyuan Oilfield’s tight oil reservoirs during high water-cut development, specifically a sharp increase in water cut after conventional fracturing and poor oil enhancement from standard measures, a pre-pad fluid water control fracturing technology was proposed. This involves pumping a large...
