The following spills were reported to the Colorado Oil and Gas Conservation Commission in the past two weeks.
Information is based on Form 19, which operators must fill out detailing the leakage/spill events. Any spill release which may impact waters of the state must be reported as soon as practical. Any spill of five barrels or more must be reported within 24 hours, and any spill of one barrel or more which occurs outside secondary containment, such as metal or earthen berms, must also be reported within 24 hours, according to COGCC rules.
Noble Energy Inc. reported on June 9 that historical impacts were discovered beneath a water vault during a facility upgrade outside of LaSalle. It is approximated that less than five barrels of produced water released. It was determined that the cause of the leak was equipment failure. The facility was shut in and removed. Remediation activities will be initiated.
Bonanza Creek Energy Operating Company LLC reported on June 9 that piping on a heater treater was corroded, outside of Briggsdale. About 15 barrels of produced water released. Roughly five barrels of produced water were released outside of containment. A vacuum truck was dispatched to remove pooled water and the impacted road base wellpad surface. Samples of soil will be collected to confirm compliance with COGCC standards.
Carrizo Niobrara LLC reported on June 9 that a mist of oil and water was released after a jet pump sustained a cracked nipple, outside of New Raymer. The wind carried the release onto an adjacent pasture. It is approximated that less than 100 barrels released. Immediately, the well was shut in and clean up efforts began within hours of the release.
DCP Midstream LP reported on June 8 that a leak originated from a pipeline, outside of Kennesburg. The leak was discovered when condensate began bubbling up from a shallow line. The line was shut in and blown down. It is approximated that more than a barrel of condensate released. Activities to remediate the leak are in progress.
EOG Resources reported on June 3 that an electrical contractor broke the sight glass on the oil phase of a treater, outside of Grover. Approximately five barrels of oil sprayed from the treater, before the sight glass could be isolated. Approximately three barrels of oil released in secondary containment and approximately two barrels of oil released outside of containment. A vacuum truck was dispatched to remove free standing oil. The equipment and soil were cleaned with a hot water wash. An excavation may be used to rid the area of stained soil.
PDC Energy Inc. reported on April 19 that during plugging and abandonment procedures, a historic release was discovered beneath a produced water vessel, outside of Eaton. It is approximated that less than five barrels of oil spill, condensate spill and produced water spill released. A photoionization detector was used to screened for volatile organic compound. Impacted material was removed and transported for disposal. Groundwater was not encountered. At the time of this release, COGCC did not require a 72-hour notification of historic impacts, if groundwater was not encountered.
