VII. Appendix A – Well Records

III. GENERAL CONDITIONS

In addition to the Standard Terms & Conditions for Construction and Reclamation, the following conditions govern this Contract:

1.0 Administrative

A. The Contract shall be overseen by DEP by an inspector specialist/project coordinator from the Abandoned Well Plugging Program. DEP may, situationally, assign alternate or assistant coordinators as staffing needs vary.

B. The Project Coordinator for the contract will be designated at the time of the issuance of the Notice to Proceed.

C. The Project Coordinator shall serve as the first point of contact for the Contractor in all matters related to the Contract.

D. The Contractor shall notify the Project Coordinator of any work stoppages or changes to planned operators at soon as practically possible.

E. All change order requests shall be submitted to the Project Coordinator for approval prior to the initiation of any work related to that change order request.

2.0 Permitting

A. Upon award of the Contract to the successful bidder, the Department shall transfer the well to and issue the plugging permit under the responsible party name, UNKNOWN

- DEP PAID PLUGGING CONTRACT.

B. The plugging portion of the Remediation and Plugging Work Plan included herein

(Section V) shall be incorporated as part of the plugging permit. This plan is developed based on best available information. Should field observations during plugging operations necessitate deviations from this plan, the Department and Contractor shall cooperate to develop alternate plans in full compliance with all applicable rules and regulations.

C. All work performed under the Contract must be completed in accordance with the most current version of the Erosion and Sediment Control Field Manual.

D. Unless otherwise specified in the Technical Specifications and/or Bid Sheet, the

Department will obtain and pay for all Local, State, and Federal permits necessary for the completion of the Contract. Any permit conditions contained within said permits shall become mandatory inclusions in the Contract.

Any disputes related to time and/or material usage determinations should be made in writing to the Project Coordinator.

C. All in-stream work required in association with the project shall be performed in accordance with all applicable local, state, and federal requirements.

D. Toilet facilities will be provided by the vendor but will not be a separate line item in the contract.

IV. PROJECT DESCRIPTION

1.0 Site-based considerations:

The well is currently leaking oil, water, and gas at the surface. The well has no surface casing or tubing above ground level. There is no storage tank located at the well site. The well is located in a hayfield, and the area around the well is flat and covered in brush. A service road will need to be constructed from the county road to the well site. No water or soil tests will be required for this site. The Office of Oil & Gas will contact Locate 811 to have all subsurface utilities marked.

2.0 Well-specific considerations:

The subject well (47-085-10441) is undocumented, so the Office of Oil & Gas has no prior drilling records for this well. The reference well used for the estimated down hole conditions is well API#

47-085-02030 (See Appendix A). The record shows well total depth (TD) @ 2047’, and then the hole is filled with stone back to 1650’. The producing formations are the Big Injun @ 1602’ and the Salt Sands @ 1497’. The record shows freshwater @ 20’, 50’, and 295’. No saltwater or coal was recorded. The record shows 20’ of 16” casing, 64’ of 10” casing, 1012’ of 6 ⅝” casing, and

1634’ of 1 ½” tubing.

V. REMEDIATION AND/OR PLUGGING WORK PLAN

Contract work may require site remediation of the well site prior to the commencement of plugging operations.

Project will commence, generally, as follows:

1. Pre-mobilization site remediation, if necessary,

2. Site preparation,

3. Connect rig to well,

4. Clean out well to total depth,

5. Set prescribed plugs and monument,

6. Reclaim site including removal of stream crossings, and

7. Submit invoice to DEP.

Proposed Work Plan

1. Notify Project Coordinator (PC) within 24 hours of plugging commencement.

2. Move in equipment and rig up to the well.

3. Trip in hole (TIH), check total depth (TD) @ or below 1700, pull all tubing and packer found in the well. If estimated depth cannot be reached, begin cleaning out hole to approved depth / TD by PC.

4. Once TD has been reached / approved by PC, a bond log will be run inside the 6 ⅝” casing to determine casing depth and cement bonding location.

5. TIH to estimated TD @ 1700’ or inspector-approved depth with tubing, spot 6% gel and pump bottom hole cement plug from 1700’ to 1400’ then trip out hole (TOH). Wait on cement (WOC), then tag top of cement plug. Add cement if needed.

6. TIH free-point 6 ⅝” casing and attempt to pull. TIH with tubing and spot gel from 1400’ to 1060’ followed by 100’ cement plug from 1060’ to 960’. WOC, tag top of plug and add cement if needed.

7. TIH with tubing and spot gel from 960’ to 700’ followed by 100’ cement plug from 700’ to 600’. WOC, tag top of plug and add cement if needed.

8. TIH with tubing and spot gel from 600’ to 350’ followed by cement plug from 350’ to surface. WOC, add cement if needed.

9. Rig down and set monument. Reclaim site.

NOTE.. Any casing found in either well without cement in the annulus that cannot be retrieved must be perforated and cement at all saltwater, freshwater, coal, oil, gas, casing shoe and elevation points.
