Okla. Stat. tit. 82 § 1020.18
When it is shown in an individual proceeding that to require the drilling of a well at the prescribed location should be inequitable or unreasonable and that criteria and conditions established by the Board in rules are met, the Board shall authorize a well location exception and permit the well to be drilled and completed at a location which varies from that previously established. Rules promulgated by the Board shall establish the criteria and conditions under which location exceptions may be authorized. Criteria and conditions for location exceptions may include, but are not limited to, compliance with terms to prevent unreasonable impact on other wells, which terms may include the rate and timing of withdrawal, the level of perforating and the level of sealing the well.
