Sour gas removal enables water reuse for unconventionals well servicing

摘要

Sour water is traditionally disposed of due to safety and process concerns. Now, it is being treated for reuse in unconventional well servicing operations using a chemical-free sweetening process that physically removes the hydrogen sulfide (H,S). AMGAS introduced the CLEAR process earlier this year. It has been used in approximately a dozen unconventional wells in the US and Australia, where access to freshwater is becoming more difficult.
