The OA shoe was downsqueezed with cement in 2003 with the TOC displaced to —2000' MD. The well developed a starting head leak which was diagnosed in 2014 during an MITOA. Current Status The well is classified as "Not Operable" by BP and is secured with a tubing tail plug with a passing CMIT TAA to 3000 psi. Objective Pump sealant down the OA into the starting head leak and squeeze the leak. Procedural steps DHD/Special projects 1. Pump sealant (squeezecrete, Well Lock, or similar product) into the OA. 2. Squeeze sealant into the starting head leak. 3. Wait on sealant to cure. DHD/Well Integrity Engineer 1. POP well Under -Evaluation and monitor starting head for any leakage. 2. If there is no leakage, convert well to Operable status. T1*E- 4-1116"QW V1Hl7EAIf FMC AC"TC R- .. OTB 443 SCV-_ -845E 6F.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor.

Perform a cement P&A of 15.8 ppg class 'G' cement with adequate cement volume to cover the 7" liner from PBTD at 11,582' to a minimum of 100' above the top perforation at 11,165' plus squeeze 5 bbls to the perforations. Estimated cement volume needed is 25 barrels. A full bore P&A is recommended but is at the discretion of the Wells Group. There are no GLM's in the completion string. Note: Top of cement must be at a minimum of 11,065' for AOGCC compliance. Top of cement may extend into the tubing as long as it does not interfere with the tubing cutting operations. 2. Rig up slickline, tag and document top of cement. 3. Cut the 4 1/2" L-80 tubing in the middle of a full joint of tubing at 4600'. This cut will not be fished and is at the discretion of the Wells Group as to chemical or jet cut. 4. Test the FMC 9-5/8" mandrel packoff and tubing hanger seals to 5000 psi for 30 minutes. 5. Test the casing against the cement plug to 3000 psi for 30 minutes. Freeze protect top 2200' MD with diesel. Ensure the cut is successful and communication exists between casinq/tubin.q to avoid tubing collapse. 6. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. 7. Remove the well house and flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. Rig Operations: 10. 11. 12. 1. MIRU Nabors 7ES 2. Circulate out freeze protection. Set TWC. 3. Nipple down tree. Nipple up and test BOPE. 4. Pull 4-1/2" tubing. 5. Make up an 8.5" bridge plug on drill pipe and set at 4200'. 6. Weight test the bridge plug and pressure test the casing to 3000 psi for 30 minutes. 7. Displace the well to milling fluid and spot a 18 ppg pill from the bridge plug to the milled section. 8. RIH with 9-5/8" Baker section mill assembly and mill a 50' window from 3900' to 3950'. 9. RIH with a mule shoe to 100' below the base of the section and spot a 17 ppg balanced cement plug from 100' below the section to 200' above the section. Kick-off drilling the 8-1/2" intermediate section to TSag @ +9687' md(8744' TVD). Run and cement a 7", 26# intermediate liner with a minimum of 150' liner lap in the 9-5/8". Test the 7" and the 9-5/8" casing from the 7" landing collar to surface to 3000 psi for 30 minutes. 13. Drill the 6" production section building 34°/100' to horizontal targeting the Sag River sands(8744' TVD) to an estimated depth of 12,403' md(8823' TVD). 14. Run a 4-1/2", 12.6# slotted production liner throughout the 6" wellbore. A Bonzai(solid/cemented and slotted) liner will be a contingency dependent on the amount of drilled 15. Run a USIT / CBT on e-line as deep as possible logging the 4.5" and 7" cement bond for 1000' above the top of the 4.5" liner. ;1 6. Test the 4-1/2", 7" and 9-5/8" casing from the 4-1/2" landing collar to surface to 4000 psi for 30 minutes. 17. 18. 19. 20. 21. 22. The 4-1/2" production liner will be perforated with DPC 2.75" guns on a 400 psi under balance. Perforating intervals to be determined after reviewing logs. Run 4-1/2" NSCT L-80 completion tying into the 4-1/2" liner. Test the tubing to 3500 psi and annulus to 3500 psi for 30 minutes with 2000 psi on the tubing. Nipple down the BOPE. Nipple up and test the tree to 5000 psi. Freeze protect the well to -2200' and secure the well. Rig down and move off.
