Prescription All Wells:

A. Pull all tubing from wellbore if applicable.

B. Plug the wellbores and reclaim the disturbed surface area of the well sites.

C. In order to place the cement in wells with water columns, it shall be pumped via tremie pipe by positive displacement or similar method (pressure grouted) from the bottom of the well to a specified depth.

D. All flowback fluids shall be captured in an above ground steel tank and disposed of at an approved disposal facility.

E. All displaced fluids shall be captured and hauled to an approved disposal facility.

F. An earthen pit may be dug to capture any cement circulated to surface and to wash up cementing equipment.

G. If the casing test fails or no test is conducted, all balanced plugs shall be tagged after a minimum wait on cement curing time of 4-hours. A casing test shall consist of

Date: September 3, 2020 pressuring up casing to 500 pounds per square inch (psi) for 30-minutes with no more than a 10% bleed off in pressure.

H. If tagged cement plug is below the prescribed depth, remedial cementing shall occur until cement can be tagged at prescribed depth.

I. Water used for plugging operations shall be from a municipal source.

J. Infrastructure removed, recontour to surrounding topography, re-seed the disturbed areas with seed mix in Appendix 15 of this document.

All wells will need Identification markers For plugging MWs

- Strip 6-inches of topsoil from a 10-foot radius around the well head and store in a pile adjacent to the work site for final reclamation. Excavate around the well casing to a depth adequate to cut and cap the well casing a minimum of 3-feet below ground surface level per surface owners’ specifications.

- Permanently weld a well identification marker to the cut off well casing. In the case of PVC casing, firmly secure marker to casing cap. The well identification marker shall be a metal plate at least ¼-inch thick. The following information shall be permanently placed on the marker by beading-on with a welding torch or engraving:

1) BLM 2) Lease serial number, 3) well name and number 4) legal location – Quarter/Quarter Section TXXN, RXXW. Bury the marker with native material.
