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 Jan. 14 that during a pressure test on a flow line outside of Kersey, it was determined that there was a loss of pressure and a leak. It is approximated that less than five barrels of condensate and less than five barrels of produced water spilled. The impacted area was uncovered, and soil that exceeded compliance with COGCC standards was found. Production equipment will remain shut-in, and an excavation of impacted soil will be scheduled.
Bonanza Creek Energy Operating Company LLC, reported on Jan. 13 that a Bonanza Creek contractor struck a well head, resulting in a leak from the wellhead piping that spilled approximately 10 barrels of oil and six barrels of water outside of Kersey. An emergency response crew arrived to stop the leak. A clean up of the soil and snow was initiated by a clean up crew. An environmentalist consultant will direct remediation activities. Soil samples will be collected to confirm compliance with COGCC standards.
Carrizo Niobrara LLC, reported on Jan. 9 that at about 8 p.m. Jan. 8 a partially cracked valve on a gas buster released an estimated amount of five barrels of E&P waste spill outside of Grover. The spill was released within containment. Cleanup efforts ensued.
Bill Barrett Corp., reported on Jan. 8 that crew from Eastern Colorado Well Service Co. cracked a pipe nipple on a well head in the process of removing a base beam outside of Gill. The beam struck the nipple creating a crack that released approximately three barrels of oil, which sprayed onto the location in a mist. It is estimated that the oil mist covered an area of 300 feet long by 100 feet wide. The heaviest mist was approximated to be within a 150-foot area from the wellhead. The area was impacted in a varying degrees. Some of the soil was covered in snow, so the oil didn’t contact the soil. Snow that was impacted was removed with a hydrovac. The well was depressured and the broken nipple was replaced. Cleanup operations were expected to take place until Jan. 9. Soil confirmation samples will be taken when the weather permits.
Noble Energy Inc., reported on Jan. 3 that a load line for a water tank froze and split outside of Briggsdale. The line released approximately 19 barrels of produced water spill inside of containment.
