Explanation of the situation that has resulted in the need to sidetrack/plug-back/temporary abandon Crestone has encountered formation instability. ii. Total measured depth reached in the wellbore being plugged back Original wellbore total depth is 8,796 ft MD-KB / 7,860 ft TVD-KB. iii. Casing set – size(s) and measured depth(s) 9 5/8” 40 lb/ft J-55 casing set at 2,590 ft MD-KB. iv. Description of fish in the hole (if any) – including top and bottom measured depths No BHA or Drillstring fish in the wellbore. v. Description of proposed plug(s): setting measured depths, heights, and cement volumes Crestone will set one (1) cement plug in the original wellbore. Cement Plug Top @ ~6,800 ft MD-KB Bottom @ 7,455 ft MD-KB Length: ~ 655 ft Volume: ~ 50 bbl (243 sxs) vi. Type of cement to be used for all plugs, including slurry weight (ppg) and yield (cf/sk) Cement to be used is 15.8 ppg Class G Cement 1.16 ft³/sk. vii. Measured depth of proposed sidetrack kick-off point Proposed sidetrack kick-off point is ~6,800 ft MD-KB. viii. Proposed objective formation(s) for sidetrack hole – new or same as the wellbore being abandoned Same original formation objective. Crestone will continue drilling original wellbore plan and run/cement production casing per original approved APD. ix. BHL target for sidetrack hole – new or same as the wellbore being abandoned (NOTE: a change in the BHL must be reviewed and approved by COGCC Permitting prior to completing the sidetrack. Drilling a sidetrack to an unapproved BHL could result in an NOAV, plugging the well, or both). Same BHL target as the original approved APD. Received email approval from Stephen Wolfe on 1/5/20 to proceed with Sidetrack Operations; see attached PDF of email. No revised Well Location Plat or Deviated Drillling Plan needed as we plan to drill the permitted formation and arrive at the same BHL. Previous Form 2 Approved prior to SB-181 Form 2 requirements were implemented. 402277438 402277438 FORM 2 SUBMITTED 402277438.pdf 402277438 402277439 WELLBORE DIAGRAM HIngley 3I ST WBD.pdf 693621 402277438 402277440 CORRESPONDENCE [EXT]Re_ Crestone Peak Resources Operating LLC - Hingley 3I-18H-N167.pdf 203267 402277438 1ST 8 3 4 5 1 2 20 12737 1780 12737 0 PLANNED 402277438 CONDUCTOR 24 16 42 127 63 127 0 0 PLANNED 402277438 SURF 13 1 2 9 5 8 40 2590 970 2590 0 0 PLANNED 402277438 CODELL CODL 320 GWA Thread was being aborted.
