Numerous instances of seismic activity in the vicinity of oil/gas drilling waste injection wells (see Shale Daily, April 17; April 8; March 19) have prompted state regulatory agencies, geologic surveys, the Interstate Oil & Gas Compact Commission (OGCC) and the Ground Water Protection Council (GWPC) to form a group to study the matter. There are nearly 151,000 Class II underground injection control wells across the country used by the oil and natural gas industry to dispose of produced water or enhance resource recovery, according to U.S. Environmental Protection Agency data. Participants in the Induced Seismicity by Injection Work Group will share research and practical experience to equip states with tools to evaluate the potential connection between tremors and injection wells and prepare for dealing with them when they happen. The effort is part of a OGCC-GWPC initiative called States First.
