04/01/2016 | The operator will collect both production and bradenhead gas samples for laboratory analysis of gas composition and stable carbon isotopes. The compositional analysis at a minimum shall include Hydrogen, Argon, Oxygen, Carbon Dioxide, Nitrogen, Carbon Monoxide, 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 (delta 13 CO2 and Delta 18O CO2).
If water is present in the bradenhead operators shall collect production and bradenhead water samples for laboratory analysis of Volatile Organic Compounds (VOCs) via EPA Method 8260 or similar and for Semi volatile Organic Compounds (SVOCs) via EPA method 8270 or similar. In addition, operator shall have the samples analyzed for the major cations and anions so that an evaluation of the water source may be conducted. The analysis shall include Na, K, Ca and Mg for cations and sulfate, chloride, bromide and total alkalinity (including bicarbonate, carbonate and total alkalinity) for anions, plus a measurement of total dissolved solids. Field water analysis should be carried out according to API RP 45. Below is the list of measurements that should be carried out immediately in the field after collecting a sample of oilfield waters: pH, Temperature, Alkalinity, Dissolved oxygen, CO2, H2S, Total and soluble iron,Turbidity on an unfiltered sample, Total suspended solids with at least primary filtration and washing performed in the field, Bacteria with filtering and/or culturing in the field and incubation and counting performed in the laboratory
Copies of all final laboratory analytical results shall be provided to the COGCC within three (3) months of collecting the samples. The analytical results shall be submitted to the COGCC in an approved electronic data deliverable format.

04/01/2016 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Properly abandon flowlines as per Rule 1103. File electronic Form 42 once abandonment complete.
3) Note- stub plug is also shoe plug. After pumping stub/shoe plug, shut down and wait on cement at minimum 4 hours. Check surface casing pressure, if pressure remains call COGCC for an update to plugging orders in order to verify gas migration has been eliminated. Plug must be tagged at 774’ or shallower. Leave at least 100’ cement in the casing for each plug. |
