Abstract: 3D Modelling and Reservoir Characterisation of the Gryphon Oilfield, U.K. North Sea Basin

TEMPLETON, G., M. ADAMS, A. JOY, Kerr-McGee Oil (U.K.) PLC, 75 Davies Street, London, W1Y 1FA, United Kingdom

The Gryphon oilfield, discovered in 1987, contains 100 MMBBL recoverable of 21° API oil in Early Eocene submarine mass flow sandstones at a depth of approximately 5600 ft subsea. The reservoir is of excellent quality (porosity 30-35% , multi-Darcy permeability, Sw 8%). However the reservoir sands occur in laterally highly discontinuous lenses with high height:width ratios in which stratification is virtually absent.

The field has recently been modelled by Kerr-McGee using non-proprietary 3D reservoir characterisation software.

A number of technical problems had to be overcome during the modelling procedure. However preliminary results from the fluid flow simulator upscaled from the 3D static geological model are encouraging. This poster illustrates some of the technical issues associated with 3D geological modelling of the Gryphon Field and highlights some of the benefits conferred upon the field by the use of this technology.
