Answer from Occidental:
Audio, visual, and olfactory (AVO) inspections are completed daily when an operator is on location. Potential leaks are reported to our emissions team to follow-up with an infrared (IR) camera. Weekly AVO inspections are completed by a member of our emissions team. Any detected leaks are recorded, repaired, and re-screened with an IR camera to verify repair. In addition, our Integrated Operations Center monitors the wells from Platteville and is staffed 24/7.
At the end of the well life cycle, we will retire the wells and reclaim the pad to match the existing landscape. This procedure is commonly referred to as plugging and abandonment and is regulated by the Colorado Oil and Gas Conservation Commission (COGCC).
