Horizontal drilling in the Permian Basin has become the main focus of drilling within the basin. Horizontal wells are actively drilling for the Sprayberry and the Wolfcamp in the Midland Basin and for the Bone Springs and the Wolfcamp in the Delaware Basin. The Permian Basin has also seen horizontal wells drilled for several other zones. The talk will begin with the early horizontal wells and bring you to present wells as well as discuss the DUC, (drilled uncompleted wells) and look at the most active operators in the basin.
