- APPENDIX 2 SUMMARY OF CONDITIONS Conditions generally are requirements in addition to or otherwise expanding upon existing regulations and guidelines. An applicant must comply with conditions or it is in breach of its approval and subject to enforcement action by the ERCB. Enforcement of an approval includes enforcement of the conditions attached to that approval. Sanctions imposed for the breach of such conditions may include the suspension of the approval, resulting in the shut-in of a facility. The conditions imposed on the waste disposal approval are summarized below. Logging CCS is required to run the following logs in the 09-01 well, in accordance with the logging requirements of Directive 051 and as discussed in Section 7.3.
- Cementing top location: A cement top locating log must be run if the production casing is not cemented to surface or cement returns to surface were not obtained and maintained during setting.
- Hydraulic isolation: The minimum logging requirements for a Class Ib well to evaluate hydraulic isolation of the disposal or injection include running a temperature survey and one of the following: radioactive tracer survey, oxygen activation log, or cement integrity log. All required logs must be submitted, accompanied by a detailed interpretation of the log against its specific objective.
- Casing integrity: A full-length casing inspection log must be run on any existing well being converted to injection or disposal service. When a casing inspection log is used to assess the casing integrity and condition, the maximum burst resistance, based on the least wall thickness and minimal yield strength of the casing, must be greater than 1.3 times the maximum allowable wellhead injection pressure (see Section 1.0 of Directive 051). CCS is encouraged to run exterior corrosion logs to optimize its evaluation of the wellbore condition. Monitoring Program The CCS monitoring program must consist of the following:
- Continuously monitoring the tubing-production casing and production-intermediate casing annuli. This includes monitoring any pressure change of both annuli 24 hours a day, seven days a week, 365 days a year. The pressure transmission of both these annuli would be relayed back to the facility SCADA screen. If an alarm condition is triggered, it would activate a call-out system. The monitoring program would be able to signal a process alarm to the operator on shift and at the same time close in a master block valve that would stop injection should the automation detect a pressure change. At that time, CCS would assess and find the reason for the alarm.
- Maintain a positive pressure on the annuli between the tubing-production casing and production-intermediate casing. This includes alarming on high and low pressures to be determined by operating performance and switch performance.
- CCS must work with ERCB staff to initiate a compliance assurance program with respect to its proposed monitoring program of the 09-01 well.
