Event description

Description

Following the 2017 DEVEX Conference, Dr Doug Boyd of Integrated Sedimentology will lead the DEVEX field trip.

The trip will visit Devonian Old Red Sandstone (ORS) exposures near Arbroath, just over an hour’s drive south of Aberdeen. The exposed sections represent excellent outcrop analogues to the Clair Field’s ORS reservoir. Horizontal and vertical core from the Clair Field will be on display at the conference, allowing comparisons to be explored.

Superbly exposed cliff and foreshore sections along the coastal path running NE of Arbroath allow sedimentological, stratigraphic and structural features of the Old Red Sandstone to be examined. Unconformable and faulted relationships between the Lower ORS and Upper ORS are evident. A wide range of sedimentological textures and structures can be seen, dominantly fluvial but arguably with other non-marine facies too. A variety of fractures and faults are also well developed.

The small scale variability of the ORS sedimentology and the development of faults and fractures will doubtless catalyse consideration of subsurface issues in Devonian reservoired fields, linking back to the Clair cores displayed at the conference. Discussion of scales, of lateral and vertical trends, of matrix and fracture system flow characteristics and interaction, and of modelling approaches, are all likely to develop.
