Pressure found on the bradenhead is within conforming parameters in COGCC guidance documents. This test is also being submitted as the 2022 annual bradenhead test as required per COGCC wellbore integrity rules. |
| 402864448 | Form 17 | 10/15/2021 | 11/9/2021 | SHUT-IN | 0 | NO FLOW | NONE | 0 | NO FLOW | 0 | 0 | No | -- | -- | Test was conducted after placement of an 80 barrel pill of 10 PPG mud down the bradenhead utilizing 1" tubing landed at 2250'. Immediately after placement of the heavy mud pill the fluid level in the bradenhead began to fall back. The bradenhead maintained full returns while placing the 10 PPG mud and only dirty water was circulated back.
It appears that the heavier mud provided enough additional hydrostatic pressure to shut off any water flowzone pressure.
Retrievable bridge plug from MIT was still present in the casing. Thus, no casing pressure was observed.
Another bradenhead test will be performed and reported prior to the end of the year. |

A water sample Analytical Sample Data Submittal Form 43 has been collected and submitted for the bradenhead fluid recovered from a 2019 bradenhead test performed 11/19/2019 and again after a prolonged bradenhead flow test concluded 9/15/2020. Both samples yielded very similar fluid analysis. Fluid recovered was approximately 7000 TDS.
A bradenhead remediation plan will now need to be submitted. In the interim the bradenhead will be flowed to the production tank to minimize the bradenhead back pressure exerted on non-cased formations. |

A pressure of 48 psi was found and a fluid sample was obtained. Analysis of the fluid sample is attached and will also be submitted on an eForm 43.
A mitigation and remediation strategy will be discussed with COGCC staff. |
