Mallard is proposing amendments to the Mottled Pad location to reduce the disturbance acreage, number of wells, and associated equipment. 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, Cultural Setbacks, Spacing & Formations, or casing/cementing program. There have been no new buildings constructed. The well site has not yet been constructed. This location is not in a buffer or exception zone, so no notices are required under Rule 305. All previously submitted notices and letters are also still valid. The Local Government Information has been updated. The SHL, TPZ, and BHL are unchanged; cultural distances from wells are unchanged but have been updated to include school facility distances. Nearest wellbore in proposed unit from anti-collision survey is the Mottled South 6-2HC. Nearest permitted or existing wellbore belonging to another operator is the Wickstrom 6-12 (API: 05-123-32065) PR Status. Well is a D Sand producer with a top interval of 6816'. The proposed well is a Niobrara with a TVD of 6217'. Producing zones are >150' apart, no 317.s required. Wickstrom 6-4 (API: 05-123-38576) PR Status is also within 150'. It is also a D Sand well with a top interval of 6845'. Producing zones are >150' apart, no 317.s required. 402427239 402427239 FORM 2 SUBMITTED 402427239.pdf 402427239 402515334 OffsetWellEvaluations Data Mottled South Pad 8N59W31 HOP Spreadsheet 2020-10-19.xlsx 43593 402427239 402427237 02A Mottled Pad fb695a5d-0d69-4aa9-81bc-164dddad77c9 402427239 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 25a30bcc-d408-4300-8fb1-5755a34454bd 402427239 1 Drilling/Completion Operations Blowout Prevention Equipment ("BOPE"): A double ram annular preventer will be used during drilling. false 7b44214d-eb6c-4adb-bd16-a7136fca5286 402427239 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 402427239 1ST 8 1 2 5 1 2 20 10715 1450 10715 0 PLANNED false false false 402427239 CONDUCTOR 26 16 43 80 50 80 0 0 PLANNED false false false 402427239 SURF 13 1 2 9 5 8 36 1555 525 1555 0 0 PLANNED false false false 402427239 NIOBRARA NBRR 535-980 640 Sec 6:All Thread was being aborted.
