All previously submitted plats, notices, Surface Use Agreements, and letters are also still valid. Well Location Plat is in COGIS Docs as Doc #401617861. The nearest well in unit per anti-collision is updated to the Mottled South 6-1HN @ 745’. The nearest outside operated well per anti-collision is updated as the Wickstrom 6-5 (API: 05-123- 21315) PR Status @56’. Well is a D Sand producer with a top interval of 6836'. The proposed well is a Niobrara with a TVD of 6235'.

Notice shall be given to all offset operators prior to drilling. false 8f973633-79f7-4c82-ab5f-c7b7d4cfa66f 403265689 1 Drilling/Completion Operations Blowout Prevention Equipment ("BOPE"): A double ram annular preventer will be used during drilling. false 9b248c43-9eb9-4d31-a142-eda5b4f9e15e 403265689 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with open-hole resistivity log with 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 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 403265689 1ST 8 1 2 5 1 2 20 10642 1425 10642 0 PLANNED HCP110 false false false 403265689 CONDUCTOR 26 16 43 80 50 80 0 0 PLANNED N/A false false false 403265689 SURF 13 1 2 9 5 8 36 1650 560 1650 0 0 PLANNED J55 false false false 403265689 NIOBRARA NBRR 535-980 640 7N-59W Sec 6: All Thread was being aborted.
