There closest well belonging to another Operator is the 1 Sun State, API 05-005-06575, operated by Bobcat Oil Co. The distances were determined by using the Offset Well Evaluation and the 3D Anti Collission Report, attached with the Directional Plan. A letter was sent to Adams-Araphoe School District 28 in August of 2019 in regard to the proximity to a school property line. No response was received. A copy of the letter is on record with the approved Form 2A. A sundry for the 2A will be submitted to update disposal method to commercial disposal as opposed to reuse/recycle. Crestone Peak is using the API number from the Abandoned Rush 4-65 29-30 3DH for this proposed well on the same pad being drilled in a new DSU. Everything regarding the wellbore has changed. Please use the original SUA that was submitted with the Rush 4-65 29-30 3DH. The location has been built and has 1 Producing well. The mineral beneath the location will be developed. This does not match the approved 2A as it was submitted with wells only going west. A new DSU is now associated with the 2A that runs underneath the location. 402440951 402440951 FORM 2 RESUBMITTED 402440951.pdf 402440951 402491248 FORM 2 REJECTED 402491248.pdf 402440951 402495007 OffsetWellEvaluations Data Rush South Pad COGCC OWE 6-30-20.xlsx 19975 402440951 402495032 LEASE MAP SurfaceMinerals Map wDSU.pdf 609095 402440951 402495038 WELL LOCATION PLAT COTTONWOOD CREEK 4-65 28-27 4DH Well Location Plat.pdf 1062523 402440951 402495040 DEVIATED DRILLING PLAN COTTONWOOD CREEK 4-65 28-27 4DH Directional Plan.pdf 384909 402440951 402495043 DIRECTIONAL DATA COTTONWOOD CREEK 4-65 28-27 4DH PLAN #0 COGCC.xlsm 37911 de52d835-93ec-4f97-af03-2e866752d050 402440951 2 Drilling/Completion Operations Crestone will comply with the “COGCC Policy for Bradenhead Monitoring During Hydraulic Fracturing Treatments in the Greater Wattenberg Area”, dated May 29, 2012. false 6efee000-448b-42b8-918a-3d04816dd114 402440951 6 Drilling/Completion Operations Adequate blowout prevention equipment will be used on all well servicing operations. false 19d8ab77-b3a8-4f36-a118-48399e6c71bf 402440951 3 Drilling/Completion Operations Alternative Logging Program: One of the first wells drilled on the pad will be logged with Open Hole Resistivity Log and Gamma Ray Log from the kick-off point to 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 measuredwhile- 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 openhole logs shall clearly state "Alternative Logging Program - No open-hole logs were run" and shall clearly identify (by API#, well name & number) the well in which openhole logs were run. false a10c1b16-6834-4265-bb5d-d9f51bd8680b 402440951 5 Drilling/Completion Operations Backup stabbing valves shall be required on well servicing operations during reverse circulation.

Pressure testing shall be conducted and the documented results will be retained by the operator for inspection by the Director for a period of one (1) year. Activation of the pipe rams for function testing shall be conducted on a daily basis when practicable. false 1d3a9d4c-4229-455d-ae40-fa952f5d6141 402440951 4 Drilling/Completion Operations No drill stem tests will be performed. false e2741e1f-8daf-4e46-bcc0-11ad95d71102 402440951 1 Drilling/Completion Operations Prior to drilling operations, Crestone will perform an anti-collision scan of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision scan will include definitive MWD or gyro surveys of the offset wells with included error of uncertainty per survey instrument, and compared against the proposed wellpath with its respective error of uncertainty. If current surveys do not exist for the offset wells, the Operator may have gyro surveys conducted to verify bottomhole location. The proposed well will only be drilled if the anti-collision scan results indicate that there is not a risk for collision, or harm to people or the environment. For the proposed well, upon conclusion of drilling operations, an as constructed gyro survey will be submitted to COGCC with the Form 5. false 402440951 1ST 8 1 2 5 1 2 20 18355 2671 18355 2328 0 PLANNED false false false 402440951 CONDUCTOR 24 16 42 99 86 99 0 0 PLANNED false false false 402440951 SURF 13 1 2 9 5 8 40 2328 1253 2328 0 0 PLANNED false false false 402440951 NIOBRARA NBRR 535-1255 1280 Sections 27 & 28 Thread was being aborted.
