07/02/2014 | you noted high BHP in October and notify COGCC with a request to vent 7 months later? please notify COGCC a little quicker in the future. Yes, vent the bradenhead to a tank to see if the pressure dissipates, and do a shut-in/build-up test afterwards to determine if the pressure has fully dissipated or if we need to remediate.

02/19/2020 | 1) Venting to maintain the bradenhead pressure below 0.25 times the surface casing setting depth (TVD) in psi is approved. Perform annual Bradenhead tests reported on a Form 17 and an annual update sundry with the duration of venting or number of times the annulus was vented.
2) COGCC staff encourages the use of a combustor for vented bradenhead gas when feasible without the use of supplemental fuel for the combustor. An enclosed flare shall be used, unless an open flare is specifically allowed by Colorado Department of Public Health and Environment (CDPHE) Regulation 7.
3) Comply with any CDPHE, Air Pollution Control Division rules or requirements for all atmospheric discharges.
4) Any liquids blown down are to be collected, stored, handled, and treated or disposed as E&P waste per COGCC’s 900 series rules.
