| Drilling/Completion Operations | Form: (02 ) 401791358 6/20/2019 | 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 to 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 clearly state "Alternative Logging Program - No open-hole logs were run" and shall clearly identify (by API#, well name & number) the well in which open-hole logs were run.

| Drilling/Completion Operations | Form: (02 ) 401791358 6/20/2019 | Bonanza Creek will comply with the “COGCC Policy for Bradenhead Monitoring during
Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012 |
| Drilling/Completion Operations | Form: (02 ) 401791358 6/20/2019 | 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. |
| Drilling/Completion Operations | Form: (02 ) 401791358 6/20/2019 | 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. |
