Summary of Degas II Performance at the U.S. Strategic Petroleum Reserve West Hackberry Site

Hogge, Joseph W.; Chojnicki, Kirsten C.; Lord, David L.

Crude oil stored at the U.S. Strategic Petroleum Reserve (SPR) requires mitigation procedures to maintain oil vapor pressure within program delivery standards. Crude oil degasification is one effective method for lowering crude oil vapor pressure, and was implemented at the West Hackberry SPR site from 2014-2018. Performance monitoring during and after degasification revealed a range of outcomes for caverns that had similar inventory and geometry.
