COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
UIC	Form: (02 ) 401151192 12/5/2016	1. Injection is not authorized until approval of Subsequent Forms 31 and 33. 2. PRIOR TO PERFORMING OPERATIONS: Operator is required to contact COGCC to discuss Step Rate Test or Injectivity Test criteria for Maximum Surface Injection Pressure determination. Prior approval of Form 4 is required for step rate and injectivity tests. 3. PRIOR TO PERFORMING OPERATIONS: Approval of Form 4 is required for acid and fracturing jobs. (New as of 4/13/2016). 4. Retrieve water sample(s) from injection zone(s) before stimulating formation. Samples must be analyzed for Total Dissolved Solids at a minimum. 5. For ALL NEW DRILL UNDERGROUND INJECTION WELLS a suite of open-hole Resistivity/Gamma Ray and Density/Neutron logs IS REQUIRED from Surface Casing shoe to TD. A PDF, TIFF, or PDS visual image and a LAS or DILS file version of each log is required. 6. For all new and converted Underground Injection Control wells a Cement Bond Log (CBL) is required on the cased portions of the hole from the bottom of the casing to the top of the next shallower casing string for all casing strings other than the Surface Casing. Only a PDF, TIFF, or PDS visual image is required. 7. Operator must provide all tops of formations encountered from surface to TD on the Form 5 when submitted.
Engineer	Form: (02 ) 401151192 12/20/2016	1) Submit Form 42 electronically to COGCC 48 hours prior to MIRU (spud notice) for the first well activity with a rig on the pad. 2) Comply with Rule 317.j. and provide cement coverage from end of 7-inch casing to a minimum of 200' above Niobrara. Verify coverage with cement bond log. 3) Bradenhead test shall be performed within 60 days of rig release and the Form 17 submitted within 10 days of the test.
UIC	Form: (04 ) 402196812 4/11/2022	Operator has permission to inject at rates of up to, but not more than 15,000 barrels per day. Maximum Surface Injection Pressure not to exceed 2,250 psi.
UIC	Form: (04 ) 402196812 4/11/2022	Operator will submit a Form 4 Sundry reporting if any recorded seismic activity greater than 2.5 magnitude within 5 miles has occurred within 30 days after they begin injection at increased pressure. Notify the UIC Lead when the Form 4 Sundry has been submitted.
UIC	Form: (04 ) 402196812 4/11/2022	Operator is required to monitor for seismic activity in the EWS 4 area. Operator will be responsible for maintenance and operation of the seismometer. Data gathered by the seismometer will be made available to one or more third parties (such as the USGS, CU-Boulder, CSM, or CSU) for analysis.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Material Handling and Spill Prevention	Form: (02 ) 401151192 2/6/2017	Load-lines. All load-lines shall be bull-plugged or capped.
Drilling/Completion Operations	Form: (02 ) 401151192 2/6/2017	Green Completions – No hydrocarbons are anticipated in this well. Hydrocarbon bearing formations will be cemented behind casing.
Drilling/Completion Operations	Form: (02 ) 401151192 2/6/2017	Blowout preventer equipment (“BOPE”). A double ram and annular preventer will be used during drilling. At least the drilling company shall have a valid well blowout prevention certifications.
Drilling/Completion Operations	Form: (02 ) 401151192 2/6/2017	BOPE for well servicing operations. Adequate BOP equipment shall be used. Stabbing valves shall be installed in the event of reverse circulation and shall be prior tested with low and high pressure fluid.
Drilling/Completion Operations	Form: (02 ) 401151192 2/6/2017	Drill stem tests. Not applicable; no drill stem tests are planned.
Drilling/Completion Operations	Form: (02 ) 401151192 2/6/2017	Open-hole Resistivity Log with Gamma Ray Log will be run from TD into the surface casing. A Cement Bond Long with Gamma Ray will be run on production casing, or on intermediate casing if a production liner is run. The Form 5, Completion Report, will list all logs run and have those logs attached.
