Make up to collar, pneumatic drill with non-sparking bit. Drill out cap venting possible trapped gas. 4) Once verified that no gas exists beneath top of surface casing plate, cut off surface casing below plate with torch, dress up smooth. 5) Butt weld surface casing to dressed cut, bringing threaded end of casing to ground level. 6) Make up to surface casing, one collar and starter well head (fitting whatever size surface casing is determined to be) 7) NU flange adaptor and 5k BOP, test BOP. 8) NU and RIH with 6 7/8" cone bit, PU 2 7/8" drill collar, 2 7/8" 8.7# tubing, and TIW valve 9) Drill out first cement plug inside surface casing (assuming there is one), roll hole clean. Verify top of next cement plug inside of surface casing by tagging (assumption). 10) If unable to verify isolation of surface casing with tag of cement plug, set RBP inside surface casing 11) Once isolation of surface casing is established, either with tagging of surface plug or setting of RBP, pressure test surface casing to 200psi 12) After pressure test of surface casing, retrieve RBP or continue drill out of cement plug under surface casing shoe. 13) Assume pressure under surface casing shoe, roll hole with kill fluid until well dead, or blow down. 14) Continue RIH, cleaning out with drilling mud or water to 6600' (or deepest possible depth, call BLM if depth is not reached) 15) TOOH with cone bit, drill collars, and 2 7/8" tubing. 16) PU and RIH with mule shoe and 2 7/8" tubing to 6500'. 17) RU cement crew and pump a balanced plug of 50 sks 15.8 ppg Class G "neat" cement. Tag balanced plug before proceding uphole 18) POOH to 6200' and pump a balanced plug of 50 sks 15.8 ppg Class G "neat" cement. Tag balanced plug before proceding uphole 19) POOH to 5900' and pump a balanced plug of 50 sks 15.8 ppg Class G "neat" cement. Tag balanced plug before proceding uphole 20) POOH to 3000' and pump a balanced plug of 50 sks 15.8 ppg Class G "neat" cement. Tag balanced plug before proceding uphole 21) POOH to 1600' and pump a balanced plug of 50 sks 15.8 ppg Class G "neat" cement. Tag balanced plug before proceding uphole 22) POOH to 855' (50' below Fox Hills base) 23) RU cement crew and pump 480 sxs of 15.8ppg Class G "neat" cement bring cement to surface *Cement calculation based on an assumed 500' of 10 3/4" surface casing and 9" open hole to 855' 24) POOH with 2 7/8" tubing. Wait 4 hrs, and tag TOC. If cement has fallen, top off back to surface 25) Let cement set over night, verify cement has not settled and is still at surface. RDMO 26) Excavate around wellhead to 8' below grade, cut off surface casing, weld on cap 27) Backfill hole and reclaim surface to original conditions bill.rains@state.co.us true 400655864 See Attached procedure of re-entry and new PA 400655864 400655864 FORM 6 INTENT SUBMITTED 400655864.pdf 400655864 400655952 LOCATION PHOTO location photos.pdf 793694 400655864 400656037 WELLBORE DIAGRAM GOVERNMENT 43-14.pdf 7936 400655864 400656038 WELLBORE DIAGRAM GOVERNMENT 43-14 proposed.pdf 17669 400655864 0 false 400655864 1 false 400655864 2 OPEN HOLE 50 6500 6778 false 400655864 3 OPEN HOLE 50 5900 6200 false 400655864 4 OPEN HOLE 50 1600 3000 false 400655864 5 OPEN HOLE 480 0 855 false 400655864 6 false 400655864 7 false 400655864 8 false 400655864 9 false 400655864 10 false 400655864 11 false 400655864 12 false 400655864 13 false 400655864 14 false 400655864 15 false 400655864 16 false 400655864 SURF 12 1 4 8 5 8 24.0 855 480 855 0 ACTUAL Thread was being aborted.
