Call IOC (970-506-5980) at least 24 hours prior to rig move. Request they catch and remove plunger, isolate production equipment, and remove any automation equipment prior to MIRU. 2 MIRU slickline. RIH to retrieve production equipment and tag for fill (last cleaned out to 7493’ on 5/7/07). Note tagged depth in OpenWells. RDMO slickline. 3 Prepare location for base beam equipped rig. Install perimeter fence as needed. 4 Check and report surface casing pressure. If surface casing is not accessible at ground level, re-plumb so valve is at ground level. 5 MIRU WO rig. Kill well as necessary with water and biocide. ND wellhead. NU BOP. 6 Unland 1.66” tbg (226 total joints landed at 7376’) and TOOH standing back 7310’ of 1.66” tubing. 7 MIRU wireline. Run gyro survey from 7296’ (100’ above top Codell perfs) to surface with stops every 100’. Forward gyro survey data and invoices to Sabrina Frantz. 8 RIH with junk basket/gauge ring (2-7/8” 6.5#) to 7350’. POOH. PU and RIH with CIBP (2-7/8”, 6.5#) to set at 7310’ (collars at 7296’ and 7328’). POOH. RDMO wireline. 9 MIRU hydrotester. Hydrotest 1.66” tubing to 3000psi while TIH open ended. Tag CIBP set at 7310’. PUH just above CIBP and circulate all gas out of the hole. Pumping water with biocide, pressure test the CIBP and production casing to 2500psi for 15 minutes. If pressure test passes, proceed to next step; otherwise contact engineering for revised procedure steps to hydrotest 2-7/8” casing back in hole to spot stub plug prior to step 18. 10 MIRU cementing services. Establish circulation with water and pump 15 sx Class “G” cement with 20% silica flour, 0.4% CD-32 and 0.4% ASA-301 mixed at 15.8ppg and 1.38 cuft/sx (cement volumes based on 2-7/8” 6.5# casing capacity from 7310’ to 6730’ with no excess). Displace cement to estimated TOC at 6670’ using approx. 12 bbls water. TOOH and stand back 13 stands of 1.66” tubing so EOT at +/- 6470’. Reverse circulate using approx. 24 bbls water (2 times tubing volume) or until returns are clean. RDMO cementing services. 11 TOOH and lay down all 1.66” tubing. 12 MIRU wireline. PU and RIH with 1-11/16” perf guns and shoot squeeze holes at 4750’ using 3 SPF, 0.5” EHD, 1’ net, 3 total shots. POOH with perf guns. RDMO wireline. 13 Establish circulation to through squeeze holes to surface with water. If circulation is established, proceed to next step; otherwise contact engineering for revised procedure steps. 14 MIRU cementing services on the 2-7/8” production casing. Establish circulation with water and pump 20 bbls sodium metasilicate followed by 330 sx Class “G” cement with 0.25 pps cello flake, 0.4% CD-32 and 0.4% ASA-301 mixed at 15.8ppg and 1.15 cuft/sx (cement volumes based on 12” caliper plus 20% excess from 4750’ to 4340’ and 2-7/8” 6.5# casing capacity from 4750’ to 4340’). Drop wiper plug and displace to 4340’ using 25 bbls water. RDMO cementing services. WOC to set up per cementing company recommendation. 15 MIRU wireline. RIH to tag cement plug @ +/- 4340’. If cement is not above 4340’ contact engineer, otherwise proceed to next step. 16 RIH and jet cut 2-7/8” production casing at 1400’. RDMO wireline. Circulate bottoms up and continue circulating to remove any gas from wellbore. 17 ND BOP. Install BOP on surface casing head with 2-7/8” pipe rams. Install 3000 psi ball valves on both casing head outlets. Install a choke or choke manifold on one outlet. 18 MIRU cementing services. Establish circulation through 2-7/8” casing with water and pump 10 bbls SAPP mud flush, 20 bbls fresh water spacer, then craig.carlile@state.co.us false 400701753 400701753 FORM 6 INTENT SUBMITTED 400701753.pdf 400701753 400701772 PROPOSED PLUGGING PROCEDURE BELL L 12-07 PROCEDURE.pdf 41533 400701753 400701774 WELLBORE DIAGRAM BELL L 12-07 WBD.pdf 70255 400701753 CODL 7396 7410 400701753 0 7310 false 400701753 1 80 15 false 400701753 2 CASING 25 6730 7310 false 400701753 3 false 400701753 4 false 400701753 5 false 400701753 6 false 400701753 7 330 4750 false 400701753 8 false 400701753 9 false 400701753 10 760 340 1400 false 400701753 11 25 false 400701753 12 false 400701753 13 false 400701753 14 25 false 400701753 15 false 400701753 16 false 400701753 1ST 7 7 8 2 7 8 6.5 7545 210 7545 6826 CBL ACTUAL 400701753 SURF 12 1 4 8 5 8 24 540 275 540 0 CALC ACTUAL Thread was being aborted.
