Review of the First Bone Spring Hybrid Play in the Delaware Basin, West Texas and Southeast New Mexico

摘要

The First Bone Spring sand received much of the drilling focus as horizontal development began in the Delaware Basin. As development moved south, deeper into the basin, operators began targeting the upper First Bone Spring sand and the emerging lower First Bone Spring shale. This stacked sequence of mixed lithologies of tight sands and organic-rich shales can be characterized as a hybrid play. Ultimately the best wells are landed in the sand, however, shale wells also showed enhanced production volumes deeper in the basin and commonly stacked with a thick sand. The Bone Spring can rival the rig-dominant Wolfcamp formation.
