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 (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 3000' 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 3000'. 17) RU cement crew and pump a balanced plug of 100 sks 15.8 ppg Class G "neat" cement 18) POOH to 1150' (150' below deepest water well @ 1000') 19) RU cement crew and pump a balanced plug of 50 sks 15.8 ppg Class G "neat" cement 20) POOH to 633' (150' below Fox Hills). RU cement crew and pump 330 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 10 3/4" casing, weld on cap 24) Backfill hole and reclaim surface to original conditions bill.rains@state.co.us true 400733134 See Atached procedure of ReEnter and new PA. 400733134 400733134 FORM 6 INTENT SUBMITTED 400733134.pdf 400733134 400733449 WELLBORE DIAGRAM current wellbore schematic.pdf 175472 400733134 400733456 WELLBORE DIAGRAM proposed wellbore schematic.pdf 297104 400733134 400733464 LOCATION PHOTO location photos.pdf 442880 400733134 400733473 PROPOSED PLUGGING PROCEDURE procedure.pdf 323360 400733134 400733484 SURFACE AGRMT/SURETY SUA.pdf 1342307 400733134 0 false 400733134 1 false 400733134 2 OPEN HOLE 100 3000 3000 false 400733134 3 OPEN HOLE 50 1150 1150 false 400733134 4 OPEN HOLE 330 0 633 false 400733134 5 false 400733134 6 false 400733134 7 false 400733134 8 false 400733134 9 false 400733134 10 false 400733134 11 false 400733134 12 false 400733134 13 false 400733134 14 false 400733134 15 false 400733134 16 false 400733134 OPEN HOLE 7 7 8 6312 ACTUAL 400733134 SURF 13 3 4 10 3 4 32.75 164 177 164 0 VISU ACTUAL Thread was being aborted.
