06/19/2014 | (1) COMPLIANCE WITH THE MOST CURRENT REVISION OF THE NORTHWEST COLORADO NOTIFICATION POLICY IS REQUIRED. SEE ATTACHED NOTICE.
(2) COGCC CONCURS WITH OPERATORS PROPOSED FIRST STRING CEMENT TOP AT THE GROUND SURFACE. AT A MINIMUM, FIRST STRING (5+1/2" CASING) CEMENT SHALL EXTEND FROM THE FIRST STRING CASING SHOE TO AT LEAST 200’ ABOVE THE SURFACE CASING SHOE TO PROVIDE FULL ISOLATION OF THE COALMONT FORMATION. FIRST STRING CEMENT COVERAGE VERIFICATION BY CBL IS REQUIRED.
(3) The operator shall monitor the production casing pressure and the bradenhead pressure of offset well HEBRON 1-18H (057-06501). The operator shall install pressure gauges on the HEBRON 1-18H well at least 24 hours prior to the operator initiating a treatment on the proposed well. The operator shall monitor the gauges at least once during every 24-hour period until 24 hours after the treatment is completed and shall continue to do so until the pressure stabilizes with allowance for a ten percent daily fluctuation. The pressure gauges shall be capable of monitoring current pressure and also capable of recording the maximum pressure encountered in a 24 hour period. Such gauges shall be reset between each 24 hour period. The pressures shall be recorded and saved for a period of one year. Alternate electronic measurement may be used to record the prescribed pressures. |

400596809
07/18/2014 | Open hole resistivity and gamma logs shall be run to describe the stratigraphy of the entire well bore and to adequately verify the setting depth of surface casing and aquifer coverage. On a multi-well pad, these open hole logs are only required on one of the first wells drilled on the pad and the Drilling Completion Report - Form 5 for every well on the pad shall identify which well was logged.

01/06/2016 | These Conditions of Approval supercede those shown on Form 2 #400958467
1) Operator shall comply with the most current revision of the Northwest Notification Policy.
2) Operator shall provide cement coverage from the production casing shoe (5+1/2" First String) to a minimum of 200' above the surface casing shoe to provide full isolation of the Coalmont Formation. Verify production casing cement coverage with a cement bond log. Changed First String cement top from a null value to 1200' (200' above proposed surface casing shoe depth of 1400'). Operator shall increase cement volume if necessary to accomplish this objective.
3) Operator Agreement, per operator agent email on 1/7/2015: "SandRidge will monitor the production casing and bradenhead pressure throughout the stimulation of Hebron 1-18HR. SandRidge will open the bradenhead of the offset well and plumb to a tank. There is potential of communication in the Niobrara downhole. If the pressure goes up and the surface casing can’t hold or if there is a leak in the casing then the pressure will go to the tank and not the formation." COGCC Monitoring Requirements: The operator shall monitor the production casing pressure and the bradenhead pressure of offset well Hebron 2-07H (057-06499). The operator shall install pressure gauges on the Hebron 2-07H well at least 24 hours prior to the operator initiating a treatment on the proposed well. The operator shall monitor the gauges at least once during every 24-hour period until 24 hours after the treatment is completed and shall continue to do so until the pressure stabilizes with allowance for a ten percent daily fluctuation. The pressure gauges shall be capable of monitoring current pressure and also capable of recording the maximum pressure encountered in a 24 hour period. Such gauges shall be reset between each 24 hour period. The pressures shall be recorded and saved for a period of one year. Alternate electronic measurement may be used to record the prescribed pressures. |

02/16/2016 | These Conditions of Approval supercede those shown on Form 2 #400596809 and previously-approved Form 4 #400964497 for Hebron 01-18HR.
1) Operator shall comply with the most current revision of the Northwest Notification Policy.
2) Operator shall provide cement coverage from the production casing shoe (5+1/2" First String) to a minimum of 200' above the surface casing shoe to provide full isolation of the Coalmont Formation. Verify production casing cement coverage with a cement bond log. Minimum required top of cement is 2300' (200' above proposed surface casing shoe depth of 2500'). Operator proposes to cement the First String to surface.
3) Operator Agreement, per operator agent email on 1/7/2015: "SandRidge will monitor the production casing and bradenhead pressure throughout the stimulation of Hebron 1- 18HR.
