UKCS Miller Field Reservoir Quality Prediction: Back to Basics?

C. R. Garland

The Miller Field, located in the South Viking Graben of the UK sector of the central North Sea, produces petroleum primarily from a series of submarine clastic reservoir sequences of Late Jurassic age. The field was discovered in 1983, and the first template well was sunk in 1989. The template wells gave the impression that the reservoir was poorer than described in the original field description, and a reduction in reserves occurred down from 301 to 240 mmbbl in 1991. Subsequently, however, not only have those template wells performed better than expected, but most of the platform wells have exceeded rock quality predicted from the reservoir description.

A programme of low-cost data acquisition via the european Thermie geochemical project, coupled with focused in-house reservoir quality studies, has assisted rock quality mapping for the 1994 reservoir model. Early indications are that this model supports an increase in Miller reserves, and perhaps a reduction in the number of wells. It is hoped that this model is two steps closer to the reality that is the Miller reservoir.
