The other wells within 150' are P&A and do not require 317.s. The Exception Location and Twinning Waiver language is included in the attached SUA, (Page 5, Section 6). Noble Energy shall isolate both the Fox Hills and Upper Pierre Aquifers with surface casing from hydrocarbon bearing zones and exposures to oil based drilling fluid. Noble Energy also agrees to not expose the Upper Pierre Aquifer to oil based mud. 401811288 401811288 FORM 2 SUBMITTED 401811288.pdf 401811288 401839516 SURFACE AGRMT/SURETY DP 131_A21-13_Redacted_NCWYO Recorded SUA.pdf 1482777 401811288 401845756 WELL LOCATION PLAT REDACTED_RAMPART A33-760 Approved 11-8-2018.pdf 1371729 401811288 401861257 DEVIATED DRILLING PLAN Rampart A33-760 APD-Rev 0.pdf 682802 401811288 401861268 DIRECTIONAL DATA Rampart A33-760 APD-Rev 0.xls 133632 401811288 401861548 OffsetWellEvaluations Data Offset Well Evaluation A21-13 Pad.xlsx 37727 401811288 401937462 EXCEPTION LOC WAIVERS DP 131 A21-13 Pad_318A.a, 318A.c exception loc (window, twinning) SUA.pdf 109161 401811288 401937467 STIMULATION SETBACK CONSENT Executed Stim Consent Waiver_Rampart A33-760, 740.pdf 1496953 401811288 401811253 02A A 21-13 Pad e82ca269-5b12-4b2d-aa4a-083541b47d4f 401811288 4 Drilling/Completion Operations If a skid is performed for the subject well, then the only required BOPE tests are for the BOPE connection bonnet seal breaks, as long as a full BOPE test was performed at the beginning of the pad, and as long as all necessary BOPE tests are completed at least every 30 days during the pad operations. false 21caa86d-fd20-40bf-8ad9-30f0439b2a22 401811288 3 Drilling/Completion Operations Anti-collision: Noble Energy 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.

All wells on the pad will have a cement bond log (CBL) 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 type of log and the well (by API#) in which open-hole logs were run. false d7e5e05d-6945-4a25-adfb-d1da4db47aac 401811288 2 Drilling/Completion Operations Bradenhead Monitoring: Noble Energy acknowledges and will comply with COGCC Policy for Braden-head Monitoring during Hydraulic Fracturing Treatments in the Greater Wattenberg Area dated May 29, 2012. false 4cdd3f76-3f07-4523-8ed2-73cd109870f7 401811288 1 General Housekeeping Housekeeping will consist of neat and orderly storage of materials and fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at offsite, suitable facilities. If spills occur prompt cleanup is required to minimize any commingling of waste materials with stormwater runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans will be used during routine fueling and maintenance to contain spills or leaks. Any waste product from maintenance will be containerized and transported offsite for disposal or recycling. There will be no major equipment overhauls conducted onsite. Equipment will be transported offsite for major overhauls. Cleanup of trash and discarded materials will be conducted at the end of each work day. Cleanup will consist of patrolling the roadway, access areas, and other work areas to pickup trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of properly. false 401811288 1ST 8 3 4 5 1 2 17 16956 1865 16956 0 PLANNED 401811288 CONDUCTOR 26 16 65 80 144 80 0 0 PLANNED 401811288 SURF 13 1 2 9 5 8 36 1850 658 1850 0 0 PLANNED 401811288 NIOBRARA NBRR 2240 Thread was being aborted.
