1) Note surface casing setting depth change from 1950’ to 2150’. Increase cement coverage accordingly.
2) Submit Form 42 electronically to COGCC 48 hours prior to MIRU.
3) Comply with Rule 317.i and provide cement coverage from TD to a minimum of 200' above Niobrara. Verify coverage with cement bond log.
4) Run and submit Directional Survey from TD to base of surface casing. The operator shall comply with Rule 321, and it shall be the operator’s responsibility to ensure that the wellbore complies with setback requirements in commission orders or rules prior to producing the well.

| Engineer | Form: (04) 401541870 06/14/2018 | This approval is good for one year and a new application must be made before February 9, 2019(1 year from prior application). Updates for the planned utilization of the well should be included with the application.
A Form 5A is required to report all plugs currently downhole which isolate the perforated interval.
The Form 7 reporting must reflect the well status dates reported on the Form 4-TA request.

| Engineer | Form: (06) 401585522 12/11/2018 | Operator shall implement measures to control venting, to protect health and safety, and to ensure that vapors and odors from well plugging operations do not constitute a nuisance or hazard to public welfare. |
| Engineer | Form: (06) 401585522 12/11/2018 | 1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Prior to placing the 2,368' plug: verify that all fluid migration (liquid or gas) has been eliminated. If evidence of fluid migration or pressure remains, contact COGCC Engineer for an update to plugging orders.
3) After isolation has been verified, pump plug and displace. If cement is not circulated to surface, shut-in, WOC 4 hours then tag plug – must be at 2,219' or shallower and provide 10 sack plug at surface.
4) Leave at least 100’ of cement in the wellbore for each plug.
5) Properly abandon on-location flowlines as per Rule 1105. File electronic Form 42 once abandonment is complete. Within 30 days of an operator completing abandonment requirements for an off-location flowline or crude oil transfer line, the operator must submit a Flowline Report, Form 44.

| Engineer | Form: (06) 401585522 12/11/2018 | If there has not been a reported Bradenhead test within 60 days of plugging this well, prior to starting plugging operations, a Bradenhead test shall be performed.
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.
3) If sampling is required contact COGCC engineering for an confirmation of plugging
requirements prior to placing any plugs.
Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting
Instructions.
The Form 17 shall be submitted within 10 days of the test.
