Permeability anisotropy evaluation for carbonate reservoirs using the curve of pressure recovery

Authors: S.S. Cherepanov (LUKOIL-PERM LLC, RF, Perm), D.A. Martyushev, I.N. Ponomareva, G.P. Khizhnyak (Perm National Research Polytechnic University, RF, Perm)

Key words: anisotropy, vertical and horizontal permeability, pressure build-up curve.

On the basis of the results of wells researches by the technique of pressure recovery assessment of vertical and horizontal permeability carbonate reservoir, as well as index anisotropy is made. The values of these coefficients for all wells Famennian-Tournaisian deposits Yurchukskogo field are calculated.
