The effect of variable skin damage along the horizontal section of the well of high-permeable reservoirs was investigated. A semi-analytical approach was used to study the simultaneous effect of perforation scenario, near wellbore formation damage and friction losses on the production of horizontal wells. Three different profiles of near wellbore damage were examined: constant skin with length, linearly decreasing from heel to toe, and steep damage of the skin versus the length. Even though the average skin was the same for the three cases, the results showed completely different inflow performance curves when friction forces were taken into account.
