The Colorado Oil and Gas Conservation Commission (COGCC) has established this Policy Regarding Bradenhead Monitoring During Hydraulic Fracturing Treatments (“Treatment”) in the Greater Wattenberg Area (“GWA”) pursuant to COGCC 207.a. (“Policy”). This Policy applies to oil and gas operations in the GWA as defined by the COGCC Rules of Practice and Procedure.
1. At least twenty (20) days prior to initiating a Treatment, the operator (“Operator”) shall provide written notice, via hand delivery, via confirmed receipt email, or via certified mail, return-receipt requested, to all adjacent operators (“Adjacent Operators”) where the Adjacent Operator’s wellbore is located within 300 feet of the Operator’s wellbore and the Adjacent Operator’s wellbore penetrates the productive zone which is to be treated by the Operator. Such notice shall include the anticipated date of the Treatment and shall provide a copy of this Policy.
2. Within seven (7) days of receipt of such notice, the Adjacent Operator shall confirm in writing to the Operator that it will comply with this Policy. If the Adjacent Operator refuses to confirm that it will comply with this Policy, or fails to timely respond to the Operator’s notice, the Operator shall advise the Commission staff of such refusal or failure by email. The Commission may then order the Adjacent Operator’s compliance.
3. The Operator shall monitor the bradenhead pressure of all wells under Operator’s control within 300 feet of the well which is to be treated, provided such other wells penetrate the productive zone which is to be treated.
4. The Operator and Adjacent Operator(s) shall install bradenhead pressure gauges on their respective wells 24 hours prior to the Operator initiating a Treatment. The Operator and Adjacent Operator(s) shall monitor their respective 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. The bradenhead 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.
5. If at any time during the Treatment or the 24-hour post-stimulation period, the bradenhead annulus pressure of the Treatment well or any offset wells subject to this Policy increases by more than 200 psig, the Operator of the well being treated, or the Adjacent Operator(s) of an affected offsetting well, as the case may be, shall verbally notify each other and the Director, as soon as practicable, but no later than twenty-four (24) hours following such incident. Within fifteen (15) days after the occurrence, the Operator or Adjacent Operator(s), as the case may be, shall submit a Sundry Notice, Form 4, giving all details, including corrective actions taken.
