155095 – Comparison of Production Results from Open Hole and Cemented Multistage Completions in the Marcellus Shale


This paper compares open hole multistage fracturing systems (OHMS) and cemented casing “plug and perf” (CCPP) completions. It presents the evolution of completion methods used in the Marcellus Shale and compares the production of wells using the two completion tecniques. A production study comparing OHMS and CCPP completed wells in two different areas within the Marcellus demonstrated higher production using OHMS compared to CCPP. The analysis also discusses the increased efficiency with decreased time and cost requirements that can result from the successful application of OHMS systems.
