This form is to be submitted as an Intent to Abandon whenever an abandonment is planned on a borehole. After the
abandonment is complete, this form shall again be submitted as a Subsequent Report of the actual work completed. The
approved intent shall be valid for six months after the approval date, after that period, a new intent will be required.
Attachments required with the Intent to Abandon are wellbore diagrams of the current configuration and the proposed
configuration with plugs set.
A Subsequent Report of Abandonment shall indicate the actual work completed. Attachments required with a Subsequent

COA Type Description
FLOWLINE AND SITE CLOSURE
1) Consistent with Rule 911.a, a Form 27 must be approved prior to cut and cap,
conducting flowline abandonment, or removing production equipment. Allow 30 days for
Director review of the Form 27; include the Form 27 document number on the Form 44
for offsite flowline abandonment (if applicable) and on the Form 6 Subsequent.
2) Properly abandon flowlines per Rule 1105. If flowlines will be abandoned in place,
include with the Form 27: pressure test results conducted in the prior 12 months as well
as identification of any document numbers for a ECMC Spill/Release Report, Form 19,
associated with the abandoned line.
For Wells with known Bradenhead pressures:
1) Provide 2 business day notice of plugging MIRU via electronic Form 42, and provide
48 hours Notice of Plugging Operations, prior to mobilizing for plugging operations via
electronic Form 42. These are 2 separate notifications, required by Rules 408.e and
408.I.
2) After placing the shallowest hydrocarbon isolating plug (1345'), operator must wait a
sufficient time to confirm static conditions.
3) After placing plug at 1345’ assure that all fluid migration has been eliminated by
monitoring the well for a minimum of 8 hours before proceeding to the next plug. If at
any time after placing this plug there is evidence of pressure or of fluid migration,
contact ECMC engineering before continuing operations.
4) Prior to placing the 1055’ plug: verify that all fluid migration (liquid or gas) has been
eliminated. If evidence of fluid migration or pressure remains, contact ECMC Engineer
for an update to plugging orders.
5) 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 924’ or shallower and
provide at least 10 sx plug at the surface.
6) After surface plug and prior to cap, verify isolation by either a 15 minute bubble test
or 15 minute optical gas imaging recording. If there is indication of flow contact ECMC
Engineering. Provide a statement on the 6SRA which method was used and what was
observed. Retain records of final isolation test for 5 years.
7) With the Form 6 SRA operator must provide written documentation which positively
affirms each COA has been addressed.
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.
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 ECMC
within three (3) months of collecting the samples.
Due to proximity to a mapped wetland, surface water and expected shallow
groundwater, operator will use secondary containment for all tanks and other liquid
containers. Operator will implement stormwater BMPs and erosion control measures as
needed to prevent sediment and stormwater runoff from entering the wetland and
surface water.
Operator committed to the following Best Management Practices under the Technical
Detail/ Comments section on the Submit Tab:
This planned location is located within a bald eagle buffer. Operations will need to be
completed outside the timing windows of 12/1 – 7/31 (eagle nest) and/or 11/15 – 3/15
(winter night roost). The eagle nest buffer window can be shortened if the nest has been
confirmed fledge for the year by CPW. If work, is planned during either window, HSE
will consult with CPW prior to operations beginning.

Step Description
1 Review Previous Open Wells Reports/Well History. If you have questions or concerns, contact Foreman/Engineer.
2 COA: Provide 48 hour notice to Colorado ECMC prior to rig up per request on approved Form 6 (e.g. call field coordinator, submit
Form 42, etc.).
3 Notify Automation Removal Group at least 24 hours prior to rig move. Request they catch and remove plunger, isolate production
equipment, and remove any automation prior to rig MIRU.
4 MIRU Slickline. Pull production equipment and tag bottom. Record tag depth, casing/tubing pressures and fluid level in Open Wells.
