COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
Engineer	Form: (02) 401485640 02/09/2018	Operator acknowledges the proximity of the following non-operated listed wells: Operator agrees to: provide mitigation option 1 or 2 (per the DJ Basin Horizontal Offset Policy) to mitigate the situation, ensure all applicable documentation is submitted based on the selected mitigation option chosen, and submit a Form 42 (“OFFSET MITIGATION COMPLETED”) for the remediated wells, referencing the API number of the proposed horizontal well(s) stating what appropriate mitigation occurred and that it has been completed, prior to the hydraulic stimulation of this well. 70 RANCH USX BB-35-03 (API NO 123-26107)
Engineer	Form: (02) 401485640 02/09/2018	1) Submit Form 42 electronically to COGCC 48 hours prior to MIRU (Spud Notice), for the first well/activity on the pad and provide 48 hour spud notice for all subsequent wells drilled on the pad. 2) Comply with Rule 317.j and provide cement coverage from the end of production casing to a minimum of 200' above Niobrara. Verify coverage with cement bond log.
Engineer	Form: (02) 401485640 02/09/2018	Bradenhead tests shall be performed and reported according to the following schedule and Form 17 submitted within 10 days of each test: 1) Within 60 days of rig release and prior to stimulation or 2) If a delayed completion, 6-7 months after rig release and prior to stimulation. 3) Within 30 days after first production, as reported on Form 5A.
Engineer	Form: (02) 401485640 02/09/2018	If a Stimulation Consent Letter is not received by the COGCC for this APD prior to the stimulation of this well. For the wells listed below and any other wells belonging to another operator now within 150’ of the completed as-drilled wellbore. In a comment on the Form 5A Submit tab, operator will provide the certification of no treated interval within 150’ and will provide the following information: well name and API number, the depth of the perforation in this well nearest to the treated interval of the offset well, and the distance between the wells at that depth. 05-123-31453, 70 RANCH USX BB #35-08
Engineer	Form: (04) 401581212 03/22/2018	Revised Surface Casing setting depth from 1400', to 1500', and adjusted cement quantities proportionately.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Planning	Form: (02 ) 401485640 2/13/2018	Wellbore Collision Prevention- Rule 317.r Prior to drilling operations, Bonanza Creek 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.
Drilling/Completion Operations	Form: (02 ) 401485640 2/13/2018	“Rule 317.p Requirement to Log a Well One of the first wells drilled on the pad will be logged with an open-hole resistivity log with 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 “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.”
Drilling/Completion Operations	Form: (02 ) 401485640 2/13/2018	Bradenhead Monitoring: Operator will comply with COGCC Policy for Bradenhead Monitoring During Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated May 29, 2012.
Drilling/Completion Operations	Form: (02 ) 401485640 2/13/2018	Stimulation Setback – Rule 317.s Prior to completions operations, Bonanza Creek shall obtain signed written consent for any portion of the proposed wellbore’s treated interval within 150’ of an existing (producing, Shut-in, or temporarily abandoned) or permitted oil and gas well’s treated interval belonging to another operator prior to completion of the well.
