There are few options to improve production and recovery in unconventional wells. To improve production with slower decline, operators are drilling longer horizontal laterals, far beyond where coiled tubing can reach. This means tractor technology is the best solution for access to the “toe” of the well. To improve recovery, refracturing in existing wells, between the previously fractured zones, is one method showing success. To accomplish this, several operators have found Welltec to be the preferred supplier of pipe cutting services which enables a liner to be set only in the horizontal section and cutting and removing the pipe near the “heel “of the well.
