Below is the description of events and approved procedure for this sidetrack: i. 8.5” drilling assembly became stuck @ ~4520’ (Sussex Fm) while TOOH from TD ii. TD - 17,471’ MD iii. 9.625” 36ppf surface casing shoe @ 1934’ iv. 8.5” bit, rotary steerable BHA, motor, (3) jts 5” HWDP, (1) severed joint of 5” DP – top of fish 4295’, bottom of fish 4528’ v. 2x 600’ (42bbls each) cement plugs from ~4200’-3000’MD vi. 17ppg (0.98cf/sk) Halliburton GraniteCem vii. ST KOP – ~3319’ viii. Same objective formation (Niobrara) will be targeted in the sidetrack ix. TPZ and BHL for sidetrack will be 76ft east and 45ft east, respectively, of the originally permitted wellbore. Verbal approval was received in the form of an email from Diana Burn on 4/10/20. (attached) The Guttersen D35-780 (API: 05-123-48588) operated by Noble, is the nearest well in the same formation, the distance was measured in 2D. The nearest well belonging to an off-set operator is the Waste Management 26KD (API: 05-123-32624, PA Status) Operated by PDC. 317.s was submitted on doc # 401866009. Waste Management 26JD (API: 05-123-32240, PA Status). Is also within 150’ of the wellbore. 317.s was submitted on doc # 401866009 All other wells within 150’ are operated by Noble, therefore no 317.s is required: Surface String casing set depth and sacks of cement are actual values from vendor post job report. Noble has provided an updated Deviated Drill Plan (attached and data uploaded). 402367254 402367254 FORM 2 SUBMITTED 402367254.pdf 402367254 402367316 DIRECTIONAL DATA Guttersen D35-770 ST01_APD - Rev 0.xls 709120 402367254 402367346 DEVIATED DRILLING PLAN Guttersen D35-770 ST01_APD Rev 0.pdf 275162 402367254 402367444 OffsetWellEvaluations Data Guttersen D35-770_OWE Data.xlsx 43383 402367254 402367453 CORRESPONDENCE COGCC_Approval.pdf 152895 402367254 402368209 WELL LOCATION PLAT Guttersen D35-770_WLC_ 4-10-2020.pdf 562119 402367254 402368210 WELLBORE DIAGRAM Current Horizontal P&A WBD.pdf 281210 402367254 402368211 WELLBORE DIAGRAM Proposed WBD.pdf 1742035 83b2865f-00ef-4218-8c1d-c680aebe0aa9 402367254 2 Drilling/Completion Operations During and Post stimulation: Operator will comply with the COGCC Policy for Bradenhead Monitoring During Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated 5/29/12. false 76b5fdc2-6bd7-4600-83b6-1a7a9e6ea02f 402367254 1 Drilling/Completion Operations Anti-collision: 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 wellpath with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottomhole 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. For the proposed well, upon conclusion of drilling operations, an as constructed gyro survey will be submitted to COGCC with the Form 5. false b43bd41b-7efb-4e30-82a3-278a57b1d3be 402367254 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with open-hole resistivity log with 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 “Alternative 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 402367254 1ST 8 1 2 5 1 2 17 17462 1834 17462 0 PLANNED 402367254 CONDUCTOR 26 16 37.05 110 64 110 0 0 PLANNED 402367254 SURF 13 1 2 9 5 8 36 1934 659 1934 0 0 PLANNED 402367254 NIOBRARA NBRR 407-2605 1280 26&35: All Thread was being aborted.
