COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
UIC	Form: (02 ) 400702543 11/17/2014	1.Daily drilling reports are required. 2.CBL of the 1st and 2nd (if present) Casing Strings required. 3.A Mudlog is required containing at least the following information: a. Rate of Penetration Log and b. Location of any drilling breaks or zones of lost circulation. 4.A static water level taken after perforation in cased wells and prior to any stimulation in either cased or open-hole wells. 5.Prior approval of Form 4 Sundry Notice is required for Step Rate and Injectivity Tests. 6.Retrieve water sample(s) from injection zone(s) before stimulating formation, Step Rate Test, or Injectivity Test. 7.A Transient Injectivity Test is required to determine the Maximum Daily Injection Rate in barrels per day (bbls/day). 8.A Transient Injectivity Test or a Step Rate Test is required to determine the Maximum Injection Pressure in pounds per square inch (psi). 9.Operators are required to install a seismometer at a location to be determined by the operator and COGCC from which seismic activity in the vicinity of the injection well can be monitored. The operator will be responsible for maintenance 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. 10.Injection is not authorized until approval of Forms 31 and 33. 11. All formation tops with no gaps from surface to TD to be provided on Form 5. Operator may determine which formations are present, but stratigraphy must extend from surface to TD.
Engineer	Form: (02 ) 400702543 11/18/2014	1) Note surface casing depth change from 950’ to 1000’. Increase cement volumes accordingly. 2) Submit Form 42 electronically to COGCC 48 hours prior to MIRU. 3) Comply with Rule 317.j and provide cement coverage from end of 7” casing to surface.
Engineer	Form: (04 ) 400840043 5/15/2015	Injection volume not to exceed 10,000 bbls and injection time not to exceed 10 days.
UIC	Form: (04 ) 400954472 12/22/2015	The NGL-C5A is approved to inject up to 15,000 barrels per day of Class II waste.
UIC	Form: (04 ) 402069055 12/18/2019	Operator is approved to increase daily injection rate from 15,000 to 17,500 barrels per day. In June 2020 operator may apply for a further rate increase. Seismic activity is to be monitored. Contact COGCC if there are any events of 2.0M Richter or higher.

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Material Handling and Spill Prevention	Form: (02 ) 400702543 11/20/2014	Load-lines. All load-lines shall be bull-plugged or capped.
Noise mitigation	Form: (02 ) 400702543 11/20/2014	If determined necessary, lighting abatement measures shall be implemented, including the installation of lighting shield devices on all of the more conspicuous lights, low density sodium lighting where practicable; and rig shrouding is not believed necessary as this is an industrial area and the only building unit within 1,000' is owned by the operator, however, at its election the operator may install temporary engineering controls consisting of perimeter sound walls during drilling and completion activities to provide noise relief. Permanent equipment on location shall be muffled to reduce noise, or shall be appropriately buffered.
Drilling/Completion Operations	Form: (02 ) 400702543 11/20/2014	Green Completions – No hydrocarbons anticipated – NA.
Drilling/Completion Operations	Form: (02 ) 400702543 11/20/2014	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 certification. 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 ) 400702543 11/20/2014	Drill stem tests. Not applicable; no Drill Stem tests are planned.
Drilling/Completion Operations	Form: (02 ) 400702543 11/20/2014	Well will be logged with an open hole logging tool with gamma ray. A CBL will be run on all production casing or, in the case of a production liner, the intermediate casing, when these casing strings are run.
Drilling/Completion Operations	Form: (02 ) 400702543 11/20/2014	Control of fire hazards. All materials which are considered fire hazards shall be a minimum of 25’ from the wellhead tanks or separators. Electrical equipment shall comply with API RP 500 and will comply with the current national electrical code. An emergency response plan has been generated for this site. No CBL over slotted liner completion.
Drilling/Completion Operations	Form: (02 ) 400702543 11/20/2014	Guy line anchors. All guy line anchors shall be brightly marked pursuant to Rule 604.c (2)Q.
Drilling/Completion Operations	Form: (02 ) 400702543 11/20/2014	Logging – A resistivity log, run from the bottom of the surface casing to total depth of the disposal well or wells or any well within one (1) mile together with a log from that well that can be correlated with the injection well. If the disposal well is to be drilled, a description of the typical stratigraphic level of the disposal formation in the disposal well or wells, and any other available logging or testing data, on the disposal well or wells will be supplied.
Final Reclamation	Form: (02 ) 400702543 11/20/2014	Well site cleared. Within 90-day subsequent to the time of plugging and abandonment of the entire site, superfluous debris and equipment shall be removed from the site. Plugged and abandoned wells will be identified. P&A’d wells shall be identified pursuant to 319.a.(5).
Underground Injection Control	Form: (02 ) 400702543 11/20/2014	Formation Water, Mechanical Integrity, & Step Rate Tests will be done prior to approval to inject.
