BSRG Workshop

North Sea core workshop at the British Sedimentological Research Group AGM


Wednesday 17thDecember

One of the highlights of this year's conference will be a unique opportunity to view specially selected cores from some of the North Sea's most famous and diverse reservoirs. The PESGB have provided generous sponsorship to ensure that this workshop is a success, with core being brought in from all corners of the United Kingdom (well, almost!).  Cores from many of the classic North Sea plays will be on display, illustrating a wide range of depositional environments and reservoir types. These include Upper Carboniferous deltas and alluvial plains, Permo-Triassic marginal aeolian deposits and dryland rivers, a range of Middle-to-Upper Jurassic deltaic and shallow-marine systems, and Cretaceous-to-Tertiary deepwater fans. The workshop will highlight the tricky business of interpreting sedimentary processes and environments from core data and will emphasise the role that core sedimentology has played, and continues to play, in reservoir characterisation, development and management. Despite new and ever more sophisticated remote-sensing technologies, cores continue to provide the direct samples that are critical to many aspects of reservoir geology, and ultimately to the efficient extraction of hydrocarbon resources.

The workshop has been organised with the co-operation of the British Geological Survey and Fugro Data Solutions and will run on 17th December. It will include presentations by students and academics that put the reservoirs into context, from both a depositional and a commercial standpoint. It is not to be missed.
