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 10 3/4" casing to dressed cut, bringing threaded end of casing to ground level. 6) Make up to 10 3/4" casing, one 10 3/4" collar and 10 3/4" 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. Assume pressure under surface casing shoe 10) RIH and set RBP inside surface casing 11) Once isolation of surface casing is established, pressure test surface casing to 200psi 12) After pressure test of surface casing, retrieve RBP. 14) Continue RIH, cleaning out with drilling mud or water to 3000'. If unable to reach this depth contact rig superintendent and wait for further instruction. 15) TOOH with cone bit, drill collars, and 2 7/8" tubing. 16) RIH with CIBP and set at 3000'. 17) RU cement crew and pump 135sk 15.8 ppg Class G "neat" cement to 2700' 18) POOH to 450' (100' below base of fresh water aquifer @ 310') 19) RU cement crew and pump 230 sxs of 15.8ppg Class G "neat" cement bring cement to surface. 25% excess cement assumed 20) POOH with 2 7/8" tubing. Wait 4 hrs, and tag TOC. If cement has fallen, top off back to surface 21) Let cement set over night, verify cement has not settled and is still at surface. RDMO 22) Excavate around wellhead to 8' below grade, cut off 10 3/4" casing, weld on cap 23) Backfill hole and reclaim surface to original conditions bill.rains@state.co.us true 400821113 See Attached procedure of re-entry and new PA. 400821113 400821113 FORM 6 INTENT SUBMITTED 400821113.pdf 400821113 400821125 WELLBORE DIAGRAM Proposed wellbore schematic.pdf 13543 400821113 400821127 WELLBORE DIAGRAM State-SLW Ranch 01 05-123-05187.pdf 9299 400821113 400821130 PROPOSED PLUGGING PROCEDURE State-SLW Ranch #01 05_123_05187 Reentry Procedure.pdf 18892 400821113 400821132 SURFACE AGRMT/SURETY SUA.pdf 254592 400821113 0 false 400821113 1 false 400821113 2 OPEN HOLE 135 2700 3000 false 400821113 3 CASING 230 0 410 false 400821113 4 false 400821113 5 false 400821113 6 false 400821113 7 false 400821113 8 false 400821113 9 false 400821113 10 false 400821113 11 false 400821113 12 false 400821113 13 false 400821113 14 false 400821113 15 false 400821113 16 false 400821113 SURF 10 3 4 8 3 4 24 353 353 0 ACTUAL Thread was being aborted.
