Groundwater Protection Council annual meet

摘要

The 2011 Meeting of the Groundwater Protection Council, a grouping of US regulators, was held in Atlanta, GA late last year. ALL Consulting's J. Daniel Arthur offered a primer on well integrity testing, noting that, contrary to popular belief, integrity testing is widely used by industry. For example, the tubular casing used in shale gas wells is tested at the steel mill. Before a frac job, it is pressured-up to check for leaks. If it fails it is replaced and tested again. Other tests are carried out at the wellsite. Arthur concluded that internal and external well integrity tests have been the cornerstone of US EPA's underground injection control (UIC-1001) program since 1980. Today, with the growth of non conventional exploitation, well integrity is more critical than ever before.
