According to the daily operations for the casing repair, cement from 2160' to 2626' was meant to have TOC at 1600 to prevent corrosion. The daily operations also said that the CBL was rushed after the cement job and that the cement coverage was not accurate. If maintain circulation do not need to tag stub plug. john.montoya@state.co.us 400436473 The Geoffroy 11-14I8 has another hole in the casing and is recommended for P&A. The P&A recommendation is based on 1) 3.5” production casing, 2) prior casing repair in 2010 (casing patch w/ annular fill), and 3) low anticipated production if repaired (estimated at 5 bopd and 30 mcfd). This well does not hold the lease and should be P&A’d immediately. 400436473 400436473 FORM 6 INTENT SUBMITTED 400436473.pdf 400436473 400436666 PROPOSED PLUGGING PROCEDURE Geoffroy 11-14I8_P&A Procedure.pdf 6482 400436473 400436669 WELLBORE DIAGRAM Geoffroy 11-14I8_Proposed Wellbore.pdf 10480 400436473 400436673 WELLBORE DIAGRAM Geoffroy 11-14I8_Current Wellbore.pdf 282622 400436473 CODL 7039 7054 400436473 JSND 7474 7520 400436473 0 2 7374 false 400436473 1 2 6939 false 400436473 2 STUB PLUG 100 1100 1500 false 400436473 3 false 400436473 4 false 400436473 5 false 400436473 6 false 400436473 7 false 400436473 8 false 400436473 9 false 400436473 10 225 0 609 true 400436473 11 false 400436473 12 false 400436473 13 false 400436473 14 false 400436473 15 false 400436473 16 false 400436473 1ST 7 7 8 3 1 2 7.7 7642 295 7642 6380 CBL ACTUAL 400436473 S.C. 1.1 7 7 8 3 1 2 7.7 7642 60 5292 5142 CBL ACTUAL 400436473 S.C. 1.2 7 7 8 3 1 2 7.7 7642 120 2626 2160 CBL ACTUAL 400436473 SURF 12 1 4 8 5 8 24 509 335 509 0 VISU ACTUAL Thread was being aborted.
