There have been no new buildings constructed and no changes to the surrounding land use, well construction plans, or mineral lease description. The well site has been constructed. The Green Teal Fed 34-27-15HN (API: 05-123-46177) and Green Teal Fed 34-27-16HN (API: 05-123-46182) have been drilled. This location is not in a buffer or exception zone, so no notices are required under Rule 305. As per the COGCC Refile Guidance Document dated March 20, 2017, no new plats or directional plans are required as the locations of the proposed wells have not moved. There are also no changes to the Surface & Minerals, Spacing & Formations, casing/cementing program, or Offset Well Evaluation. All previously submitted notices, Surface Use Agreements, and letters are also still valid. The Cultural Distances information is unchanged but has been updated to include School Facility information not submitted with the original permits but included in Google Spreadsheet bulk upload in June 2019. Local Government Information has also been added. BMP’s have been updated to reflect current standards. 402239251 402239251 FORM 2 SUBMITTED 402239251.pdf 082741da-7728-47ae-baad-6f3a5414285d 402239251 1 Drilling/Completion Operations Blowout Prevention Equipment ("BOPE"): A double ram annular preventer will be used during drilling. false 4ea2c067-a937-4b86-aaa7-eb7d0385fac0 402239251 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with an 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 “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. false 7b90931f-e735-4d80-96de-aba765e2ea45 402239251 2 Drilling/Completion Operations Anti-collision: Operator 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 shall be given to all offset operators prior to drilling. false 402239251 1ST 8 1 2 5 1 2 20 16058 2525 16058 0 0 PLANNED 402239251 CONDUCTOR 26 16 43 80 50 80 0 0 PLANNED 402239251 SURF 12 1 4 9 5 8 36 1555 425 1555 0 0 PLANNED 402239251 NIOBRARA NBRR 535-896 1280 Sec 27 & 34 - All Thread was being aborted.
