Distance from the proposed wellbore to nearest existing or proposed wellbore belonging to another operator, including plugged wells, was measured in 2D to the Brighton Lakes 20-17 1CDH, API# 05-001-10127, owned by Petroshare Corporation. This well has a bottom hole location beyond the unit boundary setback. The bottom of the completed interval will be within the unit boundary setback at 200' FNL and 2158'’ FWL of Section 17. The wellbore beyond the unit boundary setback will be physically isolated and will not be completed. The Exception Location Waiver for Rule 318A.a and Rule 318A.c is in the attached Surface Use Agreement on page 13 section 6.15 (B). The API is being reused from a previously submitted Brighton Lakes APD.

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 21cc718e-fe18-4289-86f2-abd5ccb1629d 402290610 2 Drilling/Completion Operations Drill stem tests (Rule 604.c.(2)L Conventional drill stem tests will not be conducted on DJ Basin horizontal wells currently being executed or planned by Great Western. If plans change in the future a well specific drill stem testing plan will be prepared for that particular well. Note that GREAT WESTERN may elect to use one of several available wireline deployed tools for the purpose of measuring down hole formation pressures and/or collecting down hole fluid samples from the target formation(s) of a particular well. false c1f51a57-86a4-4f4e-8c24-aea746affd97 402290610 6 Drilling/Completion Operations Multi Well Open-Hole Logging – Rule 317.p 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 “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 331e69ef-db83-475a-b200-c6882701e9db 402290610 5 Drilling/Completion Operations Bradenhead Monitoring Great Western will comply with the “COGCC Policy for Bradenhead Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012 false 402290610 1ST 8 1 2 5 1 2 17 18168 2297 18168 4323 0 PLANNED false false false 402290610 SURF 13 1 2 9 5 8 36 1700 717 1700 0 0 PLANNED false false false 402290610 NIOBRARA NBRR 407-2901 640 Sec 17, 20 W 1/2 Thread was being aborted.
