167659 – Comparative Study of Open Hole and Cemented Multistage Vertical Completion Technologies in the Permain Basin


The Permian Basin is one of the top five resource plays in the United States and consists of a number of stacked pay zones. Two of these formations, the Wolfcamp shale and Bone Spring (Wolfbone), together deliver a pay zone thickness of 1,000 to 1,500 ft. Horizontal completions in the shales are just beginning and have yet to be proven; however, operators are successfully exploiting the reserves through vertical wells. By comparing the “plug and perf” (CLPP) method and open hole multistage systems (OHMS), this paper highlights OHMS as a long-term solution for operators completing vertical wells in stacked pay.
