The effect of addition of polymer on viscosity as fluid of industrial oil and gas injection in EOR method

Abstract

One EOR injection is polymer injection. In this study we will use FP3300S polymer with a concentration of 500ppm, 750ppm, 1,000ppm, 1,250ppm, 1,500ppm, 1,750ppm, 2,000ppm, 2,250ppm and 2,500ppm. The purpose and objective of this study was to determine the effect of polymer concentration on increasing viscosity, determine the effect of polymer concentration on polymer filtration (compatibility, filtration, screen factor, thermal stability), and to find out how the polymer injection results, the higher the research found. the polymer concentration the higher the viscosity where the highest at the polymer concentration 2,500ppm with 19,38cp, the viscosity required by the polymer as injection liquid is the viscosity of the polymer greater than 2X the viscosity of the oil to be injected, where the oil viscosity is 5,2pp. then while in polymer screening it was found that higher polymer concentrations were not always good for polymer filtration, and polymer injection has been shown to increase recovery factor, recovery factor was obtained at 51.5% water injection and polymer injection was 23.1%, before injection was correct really need to be screened first, to get the most optimal concentration to be injected.
