Explanation of the situation that has resulted in the need to sidetrack: The wellbore was not drilled to the intended well plan due to an error in transferring the directional plan data by the directional driller on the rig. After reviewing the as- drilled directional survey, we would like to drill a sidetrack surface hole that follows the original intended well plan. Total measured depth reached in the wellbore being plugged back: 1,724’ MD Casing set – size(s) and measured depth(s):. No casing set. Description of fish in the hole (if any) – including top and bottom measured depths: None Description of proposed plugs: setting measured depths, heights, and cement volumes: 350’ cement plug, set from 650’ MD – 300’ MD 295 sacks Class G cement, 15.8 ppg slurry, 1.184 cu ft/sk yield, 197 BBLs of 17.5 ppg Spacer Type of cement to be used for all plugs, including slurry weight (ppg) and yield (cf/sk): 295 sacks Class G cement 15.8 ppg slurry 1.184 cu ft/sk, 197 BBLs of 17.5 ppg Spacer Measured depth of proposed sidetrack kick-off point: 300’ MD Proposed objective formation(s) for sidetrack hole: Surface hole, target TD of 1625’ MD BHL target for sidetrack hole: Same BHL target as original wellbore. 402944199 402944199 FORM 2 SUBMITTED 402944199.pdf 402944199 402944369 OffsetWellEvaluations Data STATE ANTELOPE E14-31-30XRLNB_20211103.xlsx 44451 402944199 402944521 WELLBORE DIAGRAM STATE ANTELOPE E14-31-30XRLNB_WBD.pdf 133242 402944199 402944523 CORRESPONDENCE STATE ANTELOPE E14-31-30XRLNB_State Correspondence.pdf 195772 9df4ab12-9cc8-4fa5-9f2f-3a661f98bff5 402944199 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with an open-hole resistivity log and gamma-ray, from the kick-off point into the surface casing. All wells on the pad will have a cement bond log (CBL) with gamma-ray run on production casing (or on intermediate casing if production liner is run) into the surface casing. The horizontal portion of every well will be logged with a measured-while drilling gamma-ray log. The Form 5, Completion Report, for each well on the pad will list all logs run and have those logs attached. The Form 5 for a well without open-hole logs shall clearly state ³Alternative Logging Program - No open-hole logs were run and shall clearly identify the type of log and the well (by API#) in which open-hole logs were run. false ea604b3b-5201-4ce2-906a-604addca8c51 402944199 2 Drilling/Completion Operations Operator will comply with the ³COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated May 29, 2012. false 77f60ae5-7b77-4fb8-a03c-b44af88fb34e 402944199 1 Drilling/Completion Operations Prior to drilling operations, Operator will perform an anti-collision scan of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision scan will include definitive MWD or gyro surveys of the offset wells with included error of uncertainty per survey instrument, and compared against the proposed well path with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottom hole location. The proposed well will only be drilled if the anti-collision scan results indicate that there is not a risk for collision, or harm to people or the environment. false 402944199 1ST 8 1 2 5 1 2 17 17112 2786 17112 0 PLANNED P-110 false false false 402944199 SURF 13 1 2 9 5 8 36 1600 743 1600 0 0 PLANNED J-55 false false false 402944199 NIOBRARA NBRR 720 GWA Thread was being aborted.
