ESPs are a main type of artificial lift being used to unload current horizontal unconventional wells. Due to their high cost and high failure rate, an operator must implement them in the most efficient manner possible. This presentation addresses a way to create a solution to make ESPs more efficient by using compression at surface.
Current ways of handling gas through ESPs are insufficient utilizing variable speed drives (VSDs). Additional gas handling equipment installed in ESPs have also encountered mixed results as designs continue to be tinkered to improve gas handling. One area that has not been researched extensively is utilizing compression to drawdown the casing annulus of a well on ESP. A preferential path of less static head pressure allows the gas to be drawn up the annulus rather than handled through the pump, thereby alleviating gas handling problems in the ESP and raising the FL over the pump.
This paper, which was accepted and presented at ATCE 2018, covers two case studies in Oklahoma involving ESP compression assistance up the annulus: one is a case study of an unconventional well of the Mississippi Lime with a low FL and moderate gas production and the second is an unconventional well in the Meramec formation with large amounts of gas production that was increased with the assistance of a compressor to the ESP. Data was collected over a six-week period and ESP performance was compared before and after the surface compressor installation for case 1. In case 2, well performance was compared for 3 different artificial lift setups: gas lift, ESP, and compression assisted ESP over a 3-month period. Both case studies show benefits for utilizing surface compression with an ESP. The biggest benefits were found to be increased production and reduced operating cost by extending ESP longevity.
An SPE member himself, Paul Munding joined Flogistix in April 2016 bringing 15+ years of experience working in the oil and gas industry. Mr. Munding had his first summer job with Marathon in 1999 working in the famous Yates Oil Field in West Texas. Subsequently he worked for Dowell-Schlumberger, Anadarko and BP over the following summers. Mr. Munding had a 10-year career with Chesapeake Energy in numerous roles from reservoir engineering to completions and production across the Mid-continent and Permian Basins. He then moved on to become Production Engineering Manager over the Delaware Basin for RKI. Mr. Munding graduated from the University of Oklahoma with a BS in Petroleum Engineering in 2003 and has his Professional Engineering certification. He is married with two children in elementary school and lives in Norman, OK.
