Estimation of influence natural fracture reservoir on the dynamics of productivity of wells complex structurally oil reservoir

Authors: V.A. Mordvinov, D.A. Martyushev (Perm National Research Polytechnic University, RF, Perm), V.I. Puzikov (Universal-Service LLC, RF, Perm)

Key words: carbonate reservoir, fracture, well test, deformation of the reservoir, well productivity.

Analysis of thin sections of core sample,s logging data and well test revealed prevailing north-west and south-east strike of natural fractures at Ozernoye oil field (object T-fm). The authors estimated the influence of reservoir natural fracturing in different sections of the deposit on the dynamics of wells productivity.
