Drilling/Completion Operations | Form: (02 ) 401179884 6/2/2017 | 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 clearly state “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 ) 401179884 6/2/2017 | Green Completions: Emission Control Systems. Green Completions: Test separators and associated flow lines and sand traps shall be installed on-site to accommodate Green completion techniques pursuant to COGCC Rules. Ward will utilize ECDswith adequate capacity, will be flanged to route gas to other or permanent oxidizing equipment and shall be provided with the equipment needed to maintain combustions where noncombustible gases are present. |
Drilling/Completion Operations | Form: (02 ) 401179884 6/2/2017 | BOPE Testing: Upon initial rig-up and once every 30 days during drilling operations, pressure testing of the casing string and each component of the BOPE will be performed to 70% of working pressure or 70% of the internal yield of the casing, whichever is less. |
Drilling/Completion Operations | Form: (02 ) 401179884 6/2/2017 | BOPE for well servicing operations: Adequate blowout prevention equipment will be used on any servicing operations associated with this well. Backup stabbing valves shall be required on well servicing operations during reverse circulation. Valves will be pressure tested before each well servicing operation using both low-pressure and high-pressure fluid. |
Drilling/Completion Operations | Form: (02 ) 401179884 6/2/2017 | BOPE: Ward will utilize drilling rigs with a minimum of a double ram and annular preventer |
Drilling/Completion Operations | Form: (02 ) 401179884 6/2/2017 | Drill Stem Tests: Drill Stem Tests are not anticipated for this location.
|
Drilling/Completion Operations | Form: (02 ) 401179884 6/2/2017 | Pit Level Indicators: Pit Level Indicators will not be needed as no pits will be used on location |
Drilling/Completion Operations | Form: (02 ) 401179884 6/2/2017 | Anti-Collision: Ward 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 will be given to all offset operators within 150 feet prior to drilling. |
Drilling/Completion Operations | Form: (02 ) 402297023 1/10/2021 | Closed Loop Drilling – Pit Restrictions Rule 604.c.(2)B.
Great Western Operating Company, LLC (GWOC) will be utilizing a closed loop drilling system.
|
Drilling/Completion Operations | Form: (02 ) 402297023 1/10/2021 | 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.
|
Drilling/Completion Operations | Form: (02 ) 402297023 1/10/2021 | Wellbore Collision Prevention – Rule 317.r
Prior to drilling operations, Great Western 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 ) 402297023 1/10/2021 | Stimulation Setback – Rule 317.s
Great Western 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 ) 402297023 1/10/2021 | 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

Drilling/Completion Operations | Form: (02 ) 402297023 1/10/2021 | 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.
