Regional Assessment of Produced Water Treatment and Disposal Practices andResearch Needs. Topical Report, July 1991-December 1994

摘要

The objective of this study is to evaluate current produced water managementpractices by focusing on the 13 leading U.S. natural gas producing regions to compare current industry practices given the regulatory situation to determine where produced water treatment research could have the most cost-effective impact on natural gas production. The results of this analysis show that produced water treatment research should focus on treatments for deoiling where surface water discharge is acceptable, organic removal where dissolved organics must be treated to achieve organic removal permit requirements of toxicity reduction, and partial demineralization where demineralization is needed to achieve permit requirements. This report describes an analysis that combines the GRI produced water demographics data base with the GRI-ProWCalc(trademark) computer cost model to determine where produced water treatment and surface discharge could be cost competitive and/or less expensive than deep well injection.
