Modeling water flooding effect on well performance in North Troyes oilfield with complex fracture networks

Due to delayed water injection, strong fracture development and insufficient pressure maintenance after long-term depletion, oil production in the North Troyes carbonate reservoir has declined year by year. Moreover, because the reservoir contains low-volatility crude oil and a c...

X‑ray computed tomography‑based experimental investigation of CO₂ miscible zone formation mechanisms and degree of miscibility

Carbon dioxide capture, utilization, and storage–enhanced oil recovery (CCUS–EOR) depends on the progressive development of CO₂–oil miscibility, yet the pressure-controlled transition from interfacial mass transfer to porous-media miscible-zone propagation remains difficult to qu...
