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. There are also no changes to the Surface & Minerals, Cultural Setbacks, or Spacing & Formations. All previously submitted notices, Surface Use Agreements, and letters are also still valid. Nearest wellbore in proposed unit per manual calculation is the Damfino 0680 7-6H31. Nearest permitted or existing wellbore belonging to another operator per GIS measurement is the South Coalmont 1 (API: 05-057-06244) PA Status. PFZ Comment: The upper shallow section of the North Park is not well defined. We used the depth and lithology components to define two separate sections; one being sand (as North Park FM) which is most likely a possible source of groundwater and the second being a shale (as Coalmont FM) which should not be a source of groundwater. The shale should not be a source of groundwater and has not been found to be a source of groundwater in the USGS dataset. 402725347 402725347 FORM 2 SUBMITTED 402725347.pdf 402725347 403001036 WELL LOCATION PLAT LF@5712645|403001036 804718 402725347 403001624 DIRECTIONAL DATA LF@5712646|403001624 31389 402725347 403001626 DEVIATED DRILLING PLAN LF@5712647|403001626 154711 402725347 403024277 OffsetWellEvaluations Data SURPRISE-DAMFINO 0680 S6 HOP Spreadsheet_20220413 (2).xlsx 42319 cfbe48dd-1d7a-4faf-9562-916ad8d05384 402725347 1 Drilling/Completion Operations Multi Well Open-Hole Logging - Rule 317.p: Alternative Logging Program: One of the first wells drilled on the pad – Damfino 2-06H (API 05-057-06482). The first well drilled on this pad has been logged with open-hole Resistivity Log and Gamma Ray Log from the kick-off point into the surface casing. That info is attached to form 5 Doc#400519230. All proposed wells related to this permit 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 “No open-hole logs were run” and shall clearly identify the well Damfino 2-06H (API 05-057-06482) in which open-hole logs were run. false fed1f3a9-8b09-4f18-82ec-a24f4fb67436 402725347 2 Drilling/Completion Operations Blowout Prevention Equipment ("BOPE"): A double ram annular preventer will be used during drilling. false 402725347 1ST 8 3 4 5 1 2 20 17116 2957 17116 0 PLANNED P110HC false false false 402725347 CONDUCTOR 26 16 42 90 190 90 0 0 PLANNED J55 false false false 402725347 SURF 12 1 4 9 5 8 36 2400 673 2400 0 0 PLANNED J55 false false false 402725347 NIOBRARA NBRR 531-63 1837 All: 31, 6, 7 Thread was being aborted.
