Alleged Violation(s):

Date of Alleged Violation:  9/1/2009 Approx. time of violation:  
 COGCC received a complaint from Mr. Norman Anderson in August 2009, regarding concerns that his domestic water well had been impacted by nearby oil and gas wells. COGCC collected a water sample from the well (DWR Permit #280098) on August 11, 2009. The water sample contained 17 mg/L dissolved methane and results of isotopic composition confirmed a thermogenic gas source. As a result, COGCC requested all oil & gas operators with wells within a half mile of the impacted water well to perform bradenhead tests. The bradenhead test performed at the Dupper #2 on October 1, 2009, indicated a hole in the production casing. COGCC collected a bradenhead gas sample from the well on the same date. The isotopic composition of the bradenhead gas sample was nearly identical to the sample collected from the Anderson water well. Based on this data, COGCC concluded that the apparent release from the Dupper #2 is the source of thermogenic impact to the Anderson water well.

Eddy Oil reimbursed Mr. Anderson for the full cost of a replacement water well. The Dupper #2 well was plugged and abandoned. Eddy Oil reached agreement with COGCC in August 2010 resulting in an AOC (Reference Cause No. 1V, Order No. 1V-349), whereby a fine in the amount of $46,200 was issued for rule violations associated with the release.
