With the increasing maturity of exploration in the North Sea Basin the challenge for reservoir geology has moved towards the exploitation of smaller and technically more demanding hydrocarbon accumulations, and the maximization of reserves from the established, producing fields. In both cases there is a growing need for more refined geological reservoir interpretation and modelling. This volume addresses some of the challenges reservoir geology faces in the 1990s: the improved prediction, description and modelling of hydrocarbon reservoirs through the use of new techniques and methods, the refined use of existing techniques, and the ever-increasing integration of data derived from a variety of sources, not least outcrops. The papers making up this volume address these problems from a variety of standpoints.
Improved reservoir prediction is discussed by Gibbons et al. who apply a combination of techniques, most notably sequence stratigraphy and petrography, to predict the potential impact carbonate-cemented horizons may have on the development strategy of the Troll Field reservoir (NCS), particularly the siting of horizontal wells. In similar vein Lahann et al. combine the techniques of sedimentology, petrography, inorganic geochemistry and production logging to unravel the controls on porosity and permeability in the Rotliegendes reservoir of the Vanguard Field (UKCS) and to explain the highly variable production rates from different reservoir intervals and wells. Clelland et al. describe how a relatively new technique, quantitative image analysis of pore structure, can surpass the more conventional petrographical methods in determining the controls on permeability in the variably dolomite cemented sandstones of the Jurassic Ribble Member of the Fulmar Field (UKCS); such knowledge leads to a better appreciation of production performance and is, therefore, a potential aid to reservoir management.
