Abstract
Summary
This paper investigates the injectivity of polymers in chalk matrix by experimental methods. Different polymers with variable molecular weight and structure was injected into a chalk core plug while monitoring the differential pressure. Based on the experimental results in this study, we found that it was possible to inject polymers with low molecular weight and low viscosity through chalk matrix core plugs, without causing major plugging of the rock.
