Phase 2 Forties Sandstone Core Facies & Reservoir Quality Database

Following on from the highly successful Phase I study, the Phase 2 Forties Sandstone Core Facies and Reservoir Quality Database describes the core database, depositional facies and fairway characteristics across the study area.

45 cored wells have been reviewed and logged and the resulting facies associations linked to wireline log character within the context of the Ichron deepwater facies scheme. New petrographic and SEM analysis have been undertaken to establish depositional and diagenetic controls on reservoir quality. Conventional core analysis data has also been cross referenced within the database to the facies and petrographic parameters. Palaeogeographic maps have been generated utilising the stratigraphic subdivision outlined in the Phase 1 database.
