OGA Guidance for Extended Well Tests and Hydraulic Fracture Plans (link)
This guidance issued by the Oil and Gas Authority (OGA) provides information on extended well tests (EWT) at onshore sites.
OGA may authorise extended periods of test production (extended well tests) from exploration or appraisal wells prior to the approval of a Field Development Plan if it can be demonstrated the licensee will thereby gain technical understanding or confidence in the performance of the field needed to progress towards a development.
If hydraulic stimulation is proposed as part of the EWT, a hydraulic fracture plan (HFP) also must be agreed with OGA. A summary of what may be required for an HFP is included in this guidance.
