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 e5104cfb-259a-4615-a9ec-de42cac75495 402404347 6 Drilling/Completion Operations Backup stabbing valves shall be required on well servicing operations during reverse circulation.

Additionally, mud chillers will be used to control cuttings odor while drilling through hydrocarbon bearing zones. false 884a6f0e-58ee-44f2-b868-a4ab6e73c09d 402404347 2 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 e9b08c6c-109a-49a1-ad28-75e6ba90ced5 402404347 4 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 a3c0a963-8ffd-4935-ab1b-2d7bb89b3574 402404347 5 Drilling/Completion Operations No drill stem tests will be performed. false 402404347 1ST 8 1 2 5 1 2 20 18115 2638 18115 2250 0 PLANNED false false false 402404347 CONDUCTOR 24 16 42 99 86 99 0 0 PLANNED false false false 402404347 SURF 13 1 2 9 5 8 40 2250 1212 2250 0 0 PLANNED false false false 402404347 NIOBRARA NBRR 535-422 1280 All 21,22 T4S-R65W Thread was being aborted.
