Despite the progress made on renewable energy, oil and gas remains the world's primary
energy source. Meanwhile, large amounts of oil deposits remain unrecovered after …

The aging of the existing reservoirs makes the hydrocarbon extraction shift toward newer
reserves, and harsh conditioned carbonates, which possess high temperature and high …

摘要热采, 气驱, 化学驱仍是目前中外应用最为广泛的三大主要的提高采收率技术.
随着提高采收率技术应用规模的扩大和逐步深入, 传统的提高采收率技术面临的挑战越来越大 …

In-situ formation of emulsions has been observed in a large amount of chemical flooding
pilots, and their effect on oil recovery is of great interest to petroleum engineers and …

The presence of gypsum or anhydrite in oil reservoirs limits the application of alkali–
surfactant–polymer (ASP) flooding using conventional alkalis such as sodium carbonate (Na …

In this paper, the current advances in chemical injection method of polymer flooding are
reviewed. The ultimate goal of polymer flooding for EOR process is to improve tertiary oil …

Over time, oil consumption has increased along with a continuous demand for petroleum
products that require finding ways to increase hydrocarbon production more economically …

The thixotropy of the hydrogel determines the ultimate hydrogel filling shape in the annulus
between the slotted liners and wellbore in horizontal wells. But the common hydrogel cannot …

The rheological behavior of microemulsion systems was systematically investigated with
mixtures of oil, brine, surfactant, cosolvent, and in some cases polymer to determine their …

The objective of this paper is to present a critical review of best practices for conducting
laboratory experiments to evaluate chemical EOR. Some legacy methods and procedures …
