Surfactant-based oil recovery processes are employed to lower the interfacial tension in
immiscible displacement processes, change the wettability of rock to a more water-wet …

Chemical enhanced oil recovery (CEOR) is a well-recognized technique for exploiting the
original oil in place (OOIP) left behind in subsurface petroleum reservoirs after primary and …

With a constant upsurge in energy demand, production from depleted and harsh reservoirs
through enhanced oil recovery techniques (EOR) has significantly increased. Among many …

Most oil fields today are mature, and the majority of the reservoirs in the Middle East are
carbonate rocks characterized by high temperature high salinity (HTHS), heterogeneous …

Despite rapid advances in renewable energy extraction and utilization, global oil demand
continues to rise. Oil displacement technologies are widely studied and applied because …

Polymer flooding is drawing lots of attention because of the technical maturity in some
reservoirs. The first commercial polymer flooding in China was performed in the Daqing …

Polymer flooding is one of the most promising chemical enhanced-oil-recovery (EOR)
techniques. It offers a high incremental-oil-recovery factor (IORF), low cost, and wide …

The polymeric surfactant can be used as an efficient agent for enhanced oil recovery (EOR)
because of its large bulk viscosity and good interfacial activity. However, there is a sparse …

There are more than 40% remaining oil trapped in the reservoir in the mature oilfield even
after second and tertiary recovery processes. High performance chemical agent was …

The concept of integrating fracturing and flooding has gained widespread recognition for its
role in advancing the development of unconventional oil and gas resources. Nonetheless …
