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 8 5/8" casing to dressed cut, bringing threaded end of casing to ground level. 6) Make up to 8 5/8" casing, one 8 5/8" collar and 8 5/8" starter well head 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, roll hole clean. Verify top of next cement plug inside of surface casing by tagging. 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 800' 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 700' (100' past deepest water well) 17) RU cement crew and pump 250sk 15.8 ppg Class G "neat" cement. Bring to surface 18) POOH with 2 7/8" tubing. Wait 4 hrs, and tag TOC. If cement has fallen, top off back to surface 19) Let cement set over night, verify cement has not settled and is still at surface. RDMO 20) Excavate around wellhead to 8' below grade, cut off 8 5/8" casing, weld on cap 21) Backfill hole and reclaim surface to original conditions jason.gomez@state.co.us true 400766332 See Attached procedure of ReEntry and new PA 400766332 400766332 FORM 6 INTENT SUBMITTED 400766332.pdf 400766332 400766409 WELLBORE DIAGRAM Current wellbore schematic.pdf 198624 400766332 400766411 WELLBORE DIAGRAM Proposed wellbore schematic.pdf 307904 400766332 400766413 LOCATION PHOTO location photos.pdf 563264 400766332 400766415 SURFACE AGRMT/SURETY SUA.pdf 278704 400766332 0 false 400766332 1 false 400766332 2 OPEN HOLE 30 6200 6920 false 400766332 3 OPEN HOLE 250 0 700 false 400766332 4 false 400766332 5 false 400766332 6 false 400766332 7 false 400766332 8 false 400766332 9 false 400766332 10 false 400766332 11 false 400766332 12 false 400766332 13 false 400766332 14 false 400766332 15 false 400766332 16 false 400766332 OPEN HOLE 7 7 8 6920 ACTUAL 400766332 SURF 12 1 4 8 5 8 24 302 30 302 0 ACTUAL Thread was being aborted.
