04/05/2017 | 1) Prior to starting repair work a bradenhead test shall be performed and the Form 17 shall be submitted within 10 days of the test. Prior to pumping any cement, collect bradenhead and production gas samples for laboratory analysis. The gas analysis shall be for composition and stable carbon isotopes. The compositional analysis at a minimum shall include Hydrogen, Argon, Oxygen, Carbon Dioxide, Nitrogen, Methane, Ethene, Ethane, Propene, Propane, Isobutane, Butane, Isopentane, Pentane, Hexanes +, Specific Gravity and British Thermal Units (BTU). Stable carbon isotope analysis shall include delta DC1, delta 13C1, delta 13C2, delta 13C3, delta 13IC4, delta 13NC4, delta 13IC5 (if possible), delta 13NC5 (if possible), delta 13C6+ (if possible) and stable isotopes of CO2 if possible. If liquid is encountered in the bradenhead then collect samples, analysis of the liquid samples shall be conducted to provide an evaluation of the liquid source. Submit 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. If sufficient condensate is present to collect a sample then it should be submitted for whole oil by GC analysis or equivalent. The analysis should include the bio-markers Phytane and Pristane. Copies of all final laboratory analytical results shall be provided to the COGCC within three months of collecting the samples in an approved electronic data deliverable format.
2) After completing repair work a Bradenhead Test shall be performed within the next 90 days and the Form 17 submitted within 10 days of the test.
3) The additional cement referenced shall be placed as indicated. The placed cement shall be verified with a CBL and documented with a Form 5. Please submit gyro survey data with the Form 5. |

11/07/2017 | 1) Prior to starting plugging operations a bradenhead test shall be performed. The Form 17 shall be submitted within 10 days of the test.
2) Provide 48 hour notice of plugging MIRU via electronic Form 42.
3) Properly abandon flowlines as per Rule 1103.
4) Operator shall implement measures to control unnecessary and excessive venting, to protect the health and safety of the public, and to ensure that vapors and odors from well plugging operations do not constitute a nuisance or hazard to public welfare.
5) Leave at least 100’ of cement in the wellbore for each plug. |
