Unit 4 Disposal/Storage<br />
4.1 Application <strong>for</strong> Class I-IV Disposal<br />
4.1.1 Background<br />
Disposal refers to the injection of fluids <strong>for</strong> purposes other than enhanced recovery or gas<br />
storage. In accordance with the <strong>Oil</strong> <strong>and</strong> <strong>Gas</strong> Conservation Act, Section 39(1)(c), ERCB<br />
approval of a scheme is required <strong>for</strong> the gathering, storage, <strong>and</strong> disposal of water produced in<br />
conjunction with oil <strong>and</strong> gas. Section 39(1)(d) requires ERCB approval of a scheme <strong>for</strong> the<br />
storage or disposal of any fluid or other substance to an underground <strong>for</strong>mation through a<br />
well.<br />
The ERCB classifies disposal wells based on the type of injection fluid. This classification<br />
system is outlined in ERCB <strong>Directive</strong> 051, Section 2.4.<br />
4.1.2 When to Make This Application<br />
If disposal of a fluid is required <strong>and</strong> you are certain that disposal at the proposed location will<br />
not cause an environmental or safety hazard <strong>and</strong> will not result in incremental hydrocarbon<br />
recovery, then you should make an application <strong>for</strong> disposal to the ERCB. As identified in<br />
ERCB General Bulletin (GB) 2000-8, the ERCB will approve a disposal well prior to<br />
completion of <strong>Directive</strong> 051 requirements. However, injection may not commence until the<br />
requirements of <strong>Directive</strong> 051 have been met, submitted, <strong>and</strong> approved by the ERCB.<br />
4.1.3 How the ERCB Processes the Application<br />
An application <strong>for</strong> disposal would likely be approved if the ERCB is satisfied that<br />
• disposal will not impact hydrocarbon recovery,<br />
• the disposal fluid will be confined to the injection <strong>for</strong>mation,<br />
• offset owners within 1.6 km of the disposal well(s) have been consulted <strong>and</strong> have no<br />
objections or concerns to the disposal scheme, <strong>and</strong><br />
• the applicant has the right to dispose into the requested <strong>for</strong>mation.<br />
