The development phase of the oil and gas life cycle covers the period after an economic discovery has been made and details the processes required to take the discovery up to, but before, the production phase.

This is covered by the OGA's field development plan (FDP) process. This covers the Assessment and Authorisation Phases.  Concept Select Documentation is submitted during the Assessment Phase and following a review the OGA should provide a letter of no objection to the selected concept. The project will then move into the Authorisation Phase where an approved field development plan is required before any new field or any significant extension of an existing field can be developed.  

Maximising recovery from clusters of fields, as well as individual fields, coupled with optimal usage of infrastructure will maximise economic recovery and value.

The OGA has developed Area Plans to consider developments, and their infrastructure, holistically rather than on an individual basis, and help to make sure that barriers to regional development are removed and critical infrastructure hubs are protected.

EOR and the use of technology can play a significant role in maximising economic recovery from the UKCS by increasing the volume of recovery, extending field life, creating and maintaining jobs, help stimulate field redevelopments and defer decommissioning activities. These two areas should be reviewed in detail during the Assessment and Authorisation Phases.
