Abstract:
This paper gives the initial results of a two- and three-dimensional (2D and 3D) geological study that aimed at describing reservoir heterogeneities. This study serves as a basis for the conditional simulation of the geometry of a fluvio-deltaic reservoir presented in a companion paper. These two studies should solve the difficult problem of interpolating between wells and thereby the problem of forecasting the extension of sedimentary bodies. The research is being carried out by Inst. Français du Pétrole and Center of Geostatistics, Paris School of Mines. The study was made in the middle Jurassic in Yorkshire, which is very similar to the Brent formation in the North Sea. In the 2D phase, an outcrop consisting of a 1-km [0.6-mile] -long and approximately 30-m [100-ft] -high cliff was described with a photogeological interpretation. The sedimentological representation was carried out by means of several vertical cross sections. In the 3D phase, 36 boreholes were continuously cored and logged behind the cliff over an area of 1 km2 [0.4 sq miles]. The boreholes were about 300 m [985 ft] apart except in one grid where the distance was progressively reduced to 20 m [66 ft]. This phase was designed to follow the evolution of the sedimentary bodies and their physical properties and to compare the correlation that could have been made (1) with fewer boreholes and (2) without the existence of the cliff. These studies provide new tools for understanding and describing the shape and heterogeneities of a reservoir.
