12/29/2021 | 1) Complete annual bradenhead testing for 2021 by 7/1/2022. If the wellhead has not be reinstalled by this date due to drilling operation, contact the area engineer with an update.
2) A separate annual bradenhead test is required for 2022. A minimum of 30 days between the delayed 2021 and 2022 tests is required.

08/09/2022 | 1) If the bradenhead pressure exceeds the adjusted threshold pressure, submit a new Form 4 Sundry -Bradenhead Plan
2) Sample bradenhead gas and submit for laboratory analysis of the gas composition and stable isotopes. The compositional analysis should include hydrogen, argon, oxygen, carbon dioxide, nitrogen, methane (C1), ethane (C2), ethene, propane (nC3), isobutane (iC4), butane (nC4), isopentane (iC5), pentane (nC5), hexanes +, specific gravity and British Thermal Units (BTU).The stable isotope analysis should include delta DC1, delta 13C1, delta 13C2, delta 13C3, delta 13iC4, delta 13nC4, delta 13iC5 (if possible), delta 13nC5 (if possible), and delta 13C of CO2 (if possible). The analytical results shall be submitted to the COGCC via Form 43 (Analytical Sample Submittal Form).
Gas sample containers should be filled in accordance with container manufacturer or laboratory recommendations; purging multiple container volumes may not be feasible due to limited gas volumes.
If water is encountered in the bradenhead during testing then samples (if sufficient quantity to analyze) should be collected and submitted for the laboratory analysis of major anions (chloride, carbonate, bicarbonate, and sulfate), cations (sodium, potassium, calcium, and magnesium) total dissolved solids (TDS), BTEX, DRO, GRO, and dissolved gasses (RSK 175). If there is a limited amount of water available then anions, cations and BTEX should be given first priority. Data from bradenhead water samples shall be submitted to the COGCC via Form 43.
Please refer to Appendix A of the COGCC Operator Instructions for Bradenhead Testing and Reporting for more information regarding testing and sampling protocol. |

09/14/2022 | 1) Operator shall comply with COGCC Rule 419. Bradenhead Monitoring, Testing, and Reporting and Rule 420. Form 17, Bradenhead Test Report
2) At least once a year shut in bradenhead for 7 days or until the pressure reaches the bradenhead threshold and perform a bradenhead test. Report results on a Form 17, as specified in Rule 420 or other Director approved submittal method.
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.
5) At least one check valve is required for annular spaces that are tied to sales line or separator. Maintain equipment for pressure regulation and check valves in good working order.
6) At least one valve is required to monitor pressure and sample flow from the bradenhead.
