Statement of Work Orphaned Oil & Gas Well Plugging - Deep Fork National Wildlife Refuge

Okmulgee, OK

1.0 BACKGROUND

Deep Fork National Wildlife Refuge (Refuge) was established in 1993 to protect bottomland hardwood forest habitat along the Deep Fork River in Okmulgee County, Oklahoma. Much of the Refuge’s approximately 10,000 acres was used extensively for oil and gas production throughout the 20th

Century. As a result, there are Orphaned and Abandoned wells spread throughout the Refuge. In an effort to prevent further environmental damage and restore habitat, the U.S. Fish and Wildlife Service

(FWS) targeted 25 of these wells already in Orphaned status for plugging in Fiscal Year 2023. All wells proposed for plugging have been determined by the Oklahoma Corporation Commission (OCC) to be

Orphaned, meaning that no responsible party can be located. National Environmental Policy Act (NEPA) requirements have been completed for this project and are available upon request from Refuge staff.

2.0 SCOPE OF WORK

The contractor shall properly plug and abandon the designated 25 Orphan wells (see Appendix) in a manner which will prevent further environmental damage. This involves placing cement plugs at strategic depths in the well in accordance with OCC standards, cutting off casing at least three feet below soil surface, and capping with a steel plate inscribed with the well number and date of plugging.

The contractor shall remove all equipment and remaining supplies from the site at the end of plugging operations. Surface reclamation is not part of these requirements.

Oklahoma Corporation Commission (OCC) is the lead regulatory agency providing standards for plugging and abandonment of oil and gas wells in Oklahoma. The contractor shall adhere to all OCC standards for completion of work. In accordance with Oklahoma Administrative Code § 165:10-11 (Oklahoma

Corporation Commission, Plugging and Abandonment), the contractor will notify OCC and file applicable forms prior to the commencement of plugging operations. OCC inspectors will provide verification that wells have been properly plugged.

3.0 LOCATION

The orphaned wells are located within Deep Fork National Wildlife Refuge, near Okmulgee, Oklahoma.

See Appendix for list and specific location of each well.

4.0 PERIOD OF PERFORMANCE

All deliverables shall be completed within 120 calendar days of issuance of Notice-to-Proceed. Due to seasonal environmental impacts to threated and endangered species within the work sites, USFWS staff will initiate site prep by April 1, 2023. Any additional site prep needed to complete plugging procedures will be the responsibility of the Contractor and must be reviewed and approved by USFWS COR and technical POC prior to starting.
