10/9/2017 | 1) Prior to starting repair work, a bradenhead test shall be performed and samples collected. The Form 17 shall be submitted within 10 days of the test. The Operator will 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. Collect samples of liquids in the Bradenhead, 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. 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) Per operator request the TOC has been changed to 861'. Fill is now planned for 1400-861'.
3) The additional cement specified shall be placed as indicated and in accordance with Rule 317.j. The placed cement shall be verified with a CBL and documented with a Form 5 SR.
4) Submit gyro survey run on 8/31/2011 with the Form 5 SR.
