Spill Description:
The completions department was drilling the first plug on the PA 514-2 well (API # 05-045-22139) after hydraulic fracturing operations were completed when a casing valve washed out resulting in loss of well control. The gas pressure was releasing through the washed out valve. 82 bbls of drilling mud was pumped downhole in order to kill the well so that the compromised valve could be replaced. The well’s high pressure caused drilling mud to mist out of the casing valve for approximately 1.5 hrs during this operation before the well was killed and brought under control. The total volume of mud released is unknown at this time but is estimated to be less than 50 bbls. The vast majority of the released mud was contained within the pad perimeter, though a small portion misted on adjacent vegetation.
