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 (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 6500' 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 18) POOH to 3000'. RU cement crew and pump a balanced plug of 100 sks 15.8 ppg Class G "neat" cement 19) POOH to 609' (150' below Fox Hills base @ 459') 20) RU cement crew and pump 250 sxs of 15.8ppg Class G "neat" cement bring cement to surface 21) POOH with 2 7/8" tubing. Wait 4 hrs, and tag TOC. If cement has fallen, top off back to surface 22) Let cement set over night, verify cement has not settled and is still at surface. RDMO 23) Excavate around wellhead to 8' below grade, cut off 8 5/8" casing, weld on cap 24) Backfill hole and reclaim surface to original conditions bill.rains@state.co.us true 400574584 See Attached procedure and new PA. 400574584 400574584 FORM 6 INTENT SUBMITTED 400574584.pdf 400574584 400574860 WELLBORE DIAGRAM Current Wellbore Schematic.pdf 274872 400574584 400574863 OTHER Location Pictures.pdf 488571 400574584 400574869 WELLBORE DIAGRAM Proposed Wellbore Schematic.pdf 439436 400574584 400574878 OTHER Re-Entry Procedure.pdf 442604 400574584 400574882 OTHER SUA.pdf 329385 400574584 0 false 400574584 1 false 400574584 2 false 400574584 3 false 400574584 4 false 400574584 5 false 400574584 6 false 400574584 7 false 400574584 8 false 400574584 9 false 400574584 10 false 400574584 11 false 400574584 12 false 400574584 13 false 400574584 14 false 400574584 15 false 400574584 16 false 400574584 SURF 12 3 4 8 5 8 24.00 504 300 504 0 ACTUAL Thread was being aborted.
