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. Spills and leaks are typically found during routine maintenance on existing wells, though some actual “spills” do occur among the 22,000-plus wells in the county.
Noble Energy Inc., reported on March 8 that a production tank developed a hole, outside of LaSalle. It is approximated that less than 100 barrels of oil spilled. The site did not contain a liner or ring. A remediation has been scheduled and all equipment has been shut in.
Noble Energy Inc., reported on March 7 that during operations a flowline leak was discovered outside of Keenesburg. It is approximated that less than five barrels of condensate and less than five barrels of produced water spilled. Repairs were made and production equipment was shut in. A site assessment and excavation has been scheduled.
Bonanza Creek Energy, reported on March 6 that when BCEI contractors were preparing to reinsert a well rod when oil spilled onto the well pad outside of Kersey. It is approximated that less than five barrels of oil spilled. A rod was inserted into the tubing and closed to stop the release.
Bayswater Exploration, reported on March 3 that residual contamination from a much older release was discovered outside of Johnstown. The contamination was discovered during a potential trade for few leases and wells with Great Western. Great Western discovered benzene traces in the groundwater. Bayswater purchased the location from Fountainhead Resources in 2012. Bayswater stated that to their knowledge, a spill had never occurred in that location, so they believe the contamination to be from a much older release. It is unknown the amount of spill that was released, though it is approximated to be less than five barrels. Bayswater is working with Great Western to determine the next step to properly clean the location.
Kerr McGee Oil & Gas, reported on March 2 that during abandonment activities hydrocarbon impacts were discovered, outside of Fort Lupton. It is unknown the amount of condensate spill and produced water that spilled, but it is approximated that less than five barrels of fluid spilled. Approximately 40 cubic yards of material was excavated for disposal. Groundwater samples were collected and submitted to a laboratory, results revealed that benzene, toluene and total xylenes concentrations were above COGCC standards. Excavation activities are ongoing.
