Abstract
Formation damage in horizontal wells has been recognized as one of the major problems limiting their production. This paper presents the results of an innovative and unique horizontal wellbore model which is designed to simulate realistic radial flow conditions for horizontal wells. The paper also summarizes the experimental procedures for the assessment of pre- and post-mud formation damage on two different permeability profiles of Berea sandstones. The results indicate that the model properly simulates the dynamic radial flow conditions. The main component of the model is a core holder (4-ft-long, 3-in-i.d. stainless-steel pipe) which is specifically designed to accommodate a cylindrical core sample with a horizontal wellbore in its center. The model simulates radial and open-hole flow conditions for horizontal well completion and production. The experimental program evaluates the pre- and post-mud damage well productivity and injectivity. A detailed permeability mapping is presented to show the effect of damage in a horizontal wellbore (skin depth and distribution).
