A total of 113 major violations cited inadequate well-casing or cementing, another problem that occurred in the BP spill. Onshore, well-casing and cementing are a key defense against groundwater contamination. On at least 54 occasions, oil and gas companies began drilling on federal land before receiving formal approval to do so, the report said.
Despite those problems, monetary fines were rarely issued, the report said. In eight states — Alaska, Arkansas, Louisiana, North Dakota, Nevada, Ohio, South Dakota and West Virginia — no fines were issued for the period studied.
Thirteen companies were cited for at least 30 violations over the period studied, topped by Oklahoma-based Williams Production RMT Co., which received 98 citations and seven fines totaling $6,000.
Colorado-based Encana Oil & Gas Inc. received 63 citations and four fines totaling $11,000, while Texas-based Anadarko E & P Co. received 61 violations and one fine totaling $5,000.
