... Summary To address the challenges associated with the complex preparation process of polymer particles for conformance control and the difficulties in combining injection and conformance control performance, a study was conducted on a thermoplastic elastic particle conformance control agent...

... Abstract Both Wintershall Dea and Equinor have successfully conducted conformance control pilots previously. Wintershall Dea's past field experience and Equinor's search for an option for a salinity tolerant chemical to prevent pre- and post-flush measures led to further investigation...

... 2 , and they are mainly designed to solve the matrix problem for far-wellbore conformance control. Overall, the project has provided a series of reliable and cost-effective swelling-rate-controllable particle gel products that can be used to solve the different reservoir conformance problems for CO...

... Abstract EOR projects implemented in Bakken and Changqing tight formations demonstrated that the fractures could cause early breakthrough of the injected CO 2 and finally led to undesirable oil recovery. Therefore, conformance control technologies should be developed for the outstanding EOR...

... Abstract As an effective conformance control method, gel treatments have been applied widely in mature oilfields to reduce excess water production by preferentially plugging the water thief zones after long-term water flooding. Performed particle gels (PPGs) are becoming more and more popular...

... Abstract This paper presents the results of laboratory tests measuring typical gel system effectiveness in conformance control. The evaluated gel systems are a metal-complexed polymer system, an organic crosslinked-polymer system, and an in-situ polymerized system. All the systems are typical...

... Abstract This paper examines a conformance control technique in which gel is placed into a heterogeneous porous medium by first injecting a high-viscosity uncrosslinked polymer solution and second, a low viscosity crosslinker. The latter step causes an unstable displacement to occur and allows...
