The publication describes the aspects of laboratory analysis of acid influence on porosity and permeability and stress-strain behaviour of terrigenous reservoir rocks using the Perm Krai field as an example. A comprehensive laboratory study procedure for free volume and core sample testing in simulated reservoir conditions is represented. Certain test results for acid injection through a rock sample are given and acidizing impact on rock properties was assessed.
