New drill pipe reduces body wear during shale drilling ///

Existing shale well designs and drilling operations, especially in the Bakken play, have led to an unprecedented increase in wear of the drill pipe body. The center of the pipe body has been observed to shine while drilling horizontal wells. This wear suggests that there exists continuous, downhole contact between the pipe body and the abrasive formation, as well as the casing. As a result, the drill pipe body wears out faster than the tool joints, reducing the life of the drill pipe, as well as the drilling efficiency, and increasing the overall cost of operations. Hence, to analyze the existing pipe body contact and to develop a comprehensive understanding of the downhole conditions, a joint effort was undertaken to model the underlying drilling scenario in a conventional shale well design, and to provide a possible solution to reduce wear.
