Lat/long is actual as drilled. Explanation of the situation that has resulted in the need to sidetrack: While attempting to to drill the curve section, we were not able to maintain the desired build rate. As we unsuccessfully attempted to correct back to plan, we identified that we would land well into the Carlile formation upon landing the curve. As a result, we projected we would need to make severe directional adjustments to get back into the target Codell formation. Total measured depth reached in the wellbore being plugged back: 8,612’ 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: None Type of cement to be used for all plugs, including slurry weight (ppg) and yield (cf/sk): None Measured depth of proposed sidetrack kick-off point: 5,420’ MD Proposed objective formation(s) for sidetrack hole: Codell BHL target for sidetrack hole: Same BHL target as original wellbore. 402955105 402955105 FORM 2 SUBMITTED 402955105.pdf 402955105 402955107 OffsetWellEvaluations Data Interchange A B.xlsx 41896 402955105 402955297 CORRESPONDENCE FW_ Interchange A S22-30-1C (API #05-014-20850) - Open Hole Sidetrack.pdf 171763 2182c1d3-b862-4b7c-8acd-6146261ae7fb 402955105 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with open-hole resistivity log and gamma-ray log from the kick-off point into the surface casing. All wells on the pad will have a cement bond log 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 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 8972747f-97db-4059-b749-7f09357e4a7a 402955105 1 Drilling/Completion Operations Anti-collision: Operator will perform an anti-collision evaluation of all active (producing, shut in, or temporarily abandoned) offset wellbores that have the potential of being within 150 feet of a proposed well prior to drilling operations for the proposed well. Notice shall be given to all offset operators prior to drilling. false d2217a32-36a4-4f2d-b322-e64176d6bda4 402955105 2 Drilling/Completion Operations Operator acknowledges and will comply with COGCC policy for Bradenhead Monitoring during Hydraulic Fracturing treatments in the Greater Wattenberg Area dated May 29, 2012. false 402955105 1ST 8 1 2 5 1 2 20 24126 3297 24126 0 PLANNED P-110 false false false 402955105 CONDUCTOR 24 16 42 80 100 80 0 0 PLANNED 5-L false false false 402955105 SURF 12 1 4 9 5 8 36 1637 575 1637 0 0 PLANNED J-55 false false false 402955105 CODELL CODL 1040 GWA Thread was being aborted.
