The most efficient completion technique for horizontal wells drilled in heterogeneous formations is their segregation into separate zones according to formation reservoir properties. A new technology of horizontal wells completion and production using profile liners with packers, dividing a horizontal wellbore into several sections, is proposed which has been field-tested on well 4395G (Bavlinsky field). Selective acidizing used in this horizontal well resulted in a 1,47-times increase of oil production rate.
