COGIS - Conditions of Approval Results

Type	Source Document	Conditions of Approval
Engineer	Form: (02) 400404170 05/02/2013	1) Provide 48 hour notice prior to spud via electronic Form 42. 2) Provide cement coverage to a minimum of 200' above Niobrara whichever is shallower. Verify coverage with cement bond log. 3) If dry hole, set 40 sk cement 50’ above Lyons, 40 sk cement 50’ above J-Sand, 40 sk cement 50’ above Niobrara, 40 sks cement across any DST w/ show, 50 sks cement from 50’ below to 50’ above surface casing shoe, 15 sks cement top of surface casing, cut 4’ below GL, weld on plate, or set dry hole marker, 5 sks cement in rat hole & 5 sks cement in mouse hole.
Engineer	Form: (04) 400654422 08/06/2014	1) Injection is not authorized until approval of Forms 31 and 33. Forms 31 and 33 are required.
UIC	Form: (04) 400654422 08/07/2014	Operator will not be allowed to inject into the Precambrian "Granite Wash" interval until they have convinced COGCC that the potential for induced seismicity is low. Ultimately COGCC may require this interval to be abandoned by plug back prior to initial injection. In addition to the standard documentation required for Forms 31 and 33 (listed below) Whiting may be required to provide local seismic data and/or a spinner survey in the well(s) as part of the justification of low potential for induced seismicity.
UIC	Form: (04) 400654422 08/08/2014	Injectivity tests are limited to total of 10,000 bbls and 10 days.
UIC	Form: (04) 401365782 08/10/2017	Approval is given for a temporary increase in the daily injection rate at the Wildhorse 16-13L from 15,000 barrels per day (approved in Sundry # 401004873) to 17,500 barrels per day through October 31, 2017. The daily rate must drop back down to 15,000 barrels per day after October 31, 2017.
UIC	Form: (04) 401461550 11/27/2017	Operator shall return well to permitted daily injection rate of 15,000 bpd (barrels per day) from increased rate of 17,500 bpd per previous agreement. See Sundry 401365782.
Engineer	Form: (04) 403575069 02/01/2024	Results of all mechanical integrity tests to be submitted on Form 21, Mechanical Integrity Test, within 30 days after the test

COGIS - Best Management Practice Results

BMP Type	Source Document	Best Management Practices
Material Handling and Spill Prevention	Form: (02 ) 400404170 5/19/2013	Spill Prevention Control and Countermeasures (SPCC) plans are in place to address any possible spill associated with oil and gas operations throughout the State of Colorado. • Materials and fluids will be stored in a neat and orderly fashion. • Waste will be collected regularly and disposed of at an offsite facility. • Prompt cleanup is required of spills to minimize waste materials entering the stormwater runoff. • Drip pans will be used during fueling and maintenance to contain spills or leaks. • Cleanup of trash and discarded material will be done at the end of the work day. • Cleanup will consist of monitoring the road, location and any other work areas. • Material to be cleaned up includes trash, scrap, and contaminated soil.
Storm Water/Erosion Control	Form: (02 ) 400404170 5/19/2013	Stormwater management plans (SWMP) are in place to address construction, drilling and operations associated with oil and gas development throughout the State of Colorado. BMPs will be constructed as necessary to prevent stormwater from leaving the construction site. BMPs used will vary according to the location, and will remain until the pad is reclaimed.
Planning	Form: (02 ) 400404170 5/19/2013	The Operator participates in the Colorado Oil & Gas Association Voluntary Baseline Groundwater Sampling Program.
