09/02/2015 | 1.Operator required to contact COGCC to discuss Step Rate Test or Injectivity Test criteria for Maximum Surface Injection Pressure determination.
2.Prior approval of Form 4 is required for step rate and injectivity tests.
3.Retrieve water sample(s) from injection zone(s) before stimulating formation. Samples must be analyzed for Total Dissolved Solids at a minimum.
4.For all new drill Underground Injection Control 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.
5.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.
6.Operator must provide all tops of formations encountered from surface to TD on the Form 5 when submitted.

11/27/2017 | On 8/10/2017 (Sundry # 401365725) operator given permission to increase daily injection rate from 15,000 bpd (barrels per day) to 20,000 bpd through October 31, 2017. Operator contacted UIC Lead in last week of October to request extension and was told to submit Sundry with request. Operator stated that their seismic monitoring consultants have not detected any seismic activity in the area. (USGS Earthquake Catalog has no reported seismic in this area.) Operator is hereby given permission to continue injection at an elevated rate of 17,500 bpd and must return to the original 15,000 bpd by April 1, 2018. The 17,500 bpd is a drop from the 20,000 bpd approved in August. |
