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.
Kerr McGee Oil and Gas Onshore LP reported on July 2 that during abandonment activities, impacted groundwater was encountered beneath a water tank, outside of Fort Lupton. It is unknown the volume of produced water that released. A sample of groundwater was tested and revealed that benzene and xylene concentrations were above COGCC standards.
Kerr McGee Oil and Gas Onshore LP reported on July 2 that during abandonment activities, impacted groundwater was discovered, while removing a produced water sump, outside of Fort Lupton. The volume of the release is unknown. A sample of groundwater revealed that levels of benzene and total xylenes exceeded COGCC standards.
Kerr McGee Oil and Gas Onshore LP reported on July 2 that the recycle water transfer line was crushed, when a sand hauler drove off the drive over ramp, outside of Fort Lupton. It is approximated that less than 100 barrels of produced water spilled. A vacuum truck was dispatched to recover the released fluids. The fluids that were recovered were disposed of at a licensed facility. The line was shut in.
Kerr McGee Oil and Gas Onshore LP reported on July 2 that during closure activities, historical impacts were discovered while removing the produced water sump outside of Platteville. It is unknown the amount of produced water and condensate that released. Groundwater samples were collected and tested, revealing that benzene and toulene concentrations were above COGCC standards. A vacuum tuck picked up approximately 80 barrels of impacted ground water.
Kerr McGee Oil & Gas Onshore LP reported on July 1 that a gasket failed, resulting in an approximate release of six barrels of produced water and three barrels of oil onto lined containment, outside of Frederick. A sample of soil will be collected to assure compliance with COGCC standards.
Noble Energy Inc. reported on June 30 that during plugging and abandonment procedures, impacted soil was discovered beneath the produced water vault outside of Gill. It is approximated that less than five barrels of produced water released. Remediation evaluations are underway and the facility is no longer in production.
DCP Midstream LP reported on June 26 that a broken pipeline was releasing condensate and natural gas into the St. Vrain River, outside of Longmont. There was no sheen or evidence of condensate released into the river, but there was the temporary bubbling of natural gas. The line was immediately shut in and blown down. The spill is under investigation and remediation activities are being planned.
DCP Midstream LP reported on June 25 that an abandoned DCP line released condensate and natural gas into the soil near a freshwater emergent wetlands area, outside of Johnstown. The extent of the release is still under investigation and the full impact is still unknown. It is approximated that less than five barrels of condensate released. So far, the investigation has revealed that the wetlands area has not been compromised, but if further investigation tells DCP differently, they will immediately notify COGCC. Remediation activities are underway and contamination will be removed accordingly.
Kerr McGee Oil & Gas Onshore LP, reported on June 24 that a motor valve was manually left open, causing an approximate release of five barrels of oil to spill in secondary containment, outside of Platteville.
