Report summary
Initial production rates, 24-hour test volumes, and cumulative 90-day flow back: it seems like tight oil producers have been overly focused on short-term well metrics. What about the longer-term performance of wells though? How exposed are investors to terminal decline rates for Wolfcamp wells? Until now, this issue has largely been unstudied. Other unconventional plays have been less reliant on artificial lift and the relative immaturity of the Wolfcamp didn't present a need to study aging wells in earnest. Because of this, operators and investors have routinely used proxy values to model tight oil terminal decline rates. We challenge that practice in this report though and find that commonly used proxies are nothing more than convenient substitutes. The true values are far different and need to be fully understood by anyone keeping tabs on the Permian A&D market.
