Focus will be placed on the key development challenges in these marginal marine clastic systems.

Duration and Logistics

A 5-day field course comprising a mix of fieldwork, classroom lectures and practical sessions. Classroom learning and field observations will be supported and reinforced by exercise work. The course will be based in Hunstanton with easy access to the coastal field area. Transport will be by coach.

Level and Audience

Intermediate. The course is intended for geologists and reservoir engineers with a knowledge of petroleum geoscience who are working on marginal marine reservoir systems, particularly those preserving evidence of tidal influence.

Exertion Level

This field course requires an EASY exertion level. The first field day is in a quarry at Leighton Buzzard and involves a walk of about 2km (1.25 miles) to the main quarry face. The remaining field locations on the Norfolk coast are accessed by walks of less than 3.5km (2 miles) along flat sandy beaches and tidal channels that may be muddy and slippery in parts.
