Concurrence of aqueous and gas phase contamination of groundwater in the Wattenberg oil and gas field of northern Colorado

Concurrence of aqueous and gas phase contamination of groundwater in the Wattenberg oil and gas field of northern Colorado Li H, Son JH, Carlson KH. Abstract The potential impact of rapid development of unconventional oil and natural gas resources using hydraulic fracturing and horizontal drilling on regional groundwater quality has received significant attention. Major concerns …

Water Resources and Shale Gas/Oil Production in the Appalachian Basin – Critical Issues and Evolving Developments

This USGS-report depicts some of the critical issues that accompany shale oil and gas operations in the Appalachian region, e. g. the tremendous freshwater consumption: Only 10% of all HVHF water used is recovered from the drilled and fractured formation in northeastern Pennsylvania. Bibliography: William M. Kappel, John H. Williams, and Zoltan Szabo Water Resources …
