... Abstract Polymer flooding, an enhanced oil recovery (EOR) method, has been widely implemented in various oil fields worldwide to increase oil recovery rates by improving the viscosity of injected water and, consequently, the sweep efficiency in the reservoir. Its implementation strategies can...

... is synthesized by polymerization in emulsion of vinyl acetate, vinyl chloride, acrylics, acrylonitrile, ethylene, styrene or butadiene. The polymers are present in the form of a colloidal solution stabilized by surfactants. Typical size of globular colloidal particles is 0.2-0.5 microns. Latex is capable...

... to limited gas handling capacity at the plant processing facilities. Hence, isolation of Bashkirian will not only stimulate lower intervals to produce, but also, reduce GOR concerns. First pilot workover to isolate Bashkirian in SGI used chemical polymers. Polymers were injected into the formation...

... Figure 2 Failure analysis of sucker rod pumping systems ( Lea, J.F., Pattillo, P.D., 1993 ) Tribology of Polymers Tribology is generally defined as the science of interacting surfaces in relative motion and related subjects and particles. The tribology system consists of two...

... and hydrophobic adhesive colmatant that provide "roughcast" of wellbore [ A.A. Khubbatov (2012) ]. Thus, injecting the polymers has regulating effect on water molecular structure that allows to change polymerized and monomeric water ratio by forming superstructures with hydrogen bond. Owing to the changed...
