02/02/2015 | 1. For all new drill Underground Injection Control wells a suite of open-hole Resistivity/Gamma Ray and Density/Neutron logs is required from Surface Casing shoe to TD. A PDF, TIFF, or PDS visual image and a LAS or DLIS file version of each log is required.
2. For all new and converted Underground Injection Control wells a Cement Bond Log (CBL) is a required on the cased portions of the hole from the bottom of the casing to the top of the next shallower casing string for all casing strings other than the Surface Casing. Only a PDF, TIFF, or PDS visual image is required.
3. A Mudlog is required containing at least the following information:
a)Rate of Penetration Log, and
b)The location of any drilling breaks or zones of lost circulation.
4. Prior approval of Form 4 Sundry Notice is required for Step Rate and Injectivity Tests.
5. Retrieve water sample(s) from injection zone(s) before stimulating formation, Step Rate Test, or Injectivity Test.
6. A Transient Injectivity Test is required to determine the Maximum Daily Injection Rate in barrels per day (bbls/day).
7. A Transient Injectivity Test or a Step Rate Test is required to determine the Maximum Injection Pressure in pounds per square inch (psi).
8.Injection is not authorized until approval of Forms 31 and 33.
9.Operator must provide all tops of formations encountered from surface to TD on the Form 5 when submitted.

05/13/2021 | Plugging
1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Contact COGCC Area Inspector prior to commencing plugging operations.
3) Plugs and squeezes will be placed as stated in the Plugging Procedure section of the approved NOIA unless revised by COA or prior approval from COGCC is obtained.
4) The wellbore must be static prior to placing cement plugs which are to be a minimum of 100' in length for all but surface plugs. Mechanical isolation requires a 25' cement plug, minimum. For plugs not specified to be tagged, a tag is required if circulation is not maintained while pumping plug and displacing to depth. Tag at tops specified or shallower. Notify COGCC Area Engineer before adding cement to previous plug.
5) Place a 50' plug (minimum) at the surface, both inside the inner most casing and in all annular spaces. Surface plugs shall be circulated to surface. Confirm cement to surface in all strings during cut and cap.
6) With the Form 6 SRA operator must provide written documentation which positively affirms each COA has been addressed.
7) 100' casing plugs at 8100', 7222' and 3100' may be replaced with a CIBP and 5 sx of cement. |

07/28/2021 | Bradenhead Testing
Prior to starting plugging operations a bradenhead test shall be performed if there has not been a reported bradenhead test within the 60 days immediately preceding the start of plugging operations.
1) If, before opening the bradenhead valve, the beginning pressure is greater than 25 psi, sampling is required.
2) If pressure remains at the conclusion of the test, or if any liquids were present during the test, sampling is required.
The Form 17 shall be submitted within 10 days of the test. Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions. If samples are collected, copies of all final laboratory analytical results shall be provided to the COGCC within three (3) months of collecting the samples.
If there is a need for sampling, contact COGCC engineering for verification of plugging procedure. |
