Objective
The software to be validated in terms of economic and technical viability is an integrated computational tool for the simulation and characterization of reservoir pore structure and the prediction of petrophysical and reservoir engineering properties. The proposed project comprises an extension of the project CARE, whose results were assessed positively by the four participating companies and generally by the oil industry as it is presented in the second part of this proposal. This project aims to increase the range of applicability of the initial product offering a cost effective alternative to expensive laboratory testing by extending the analysis of homogeneous porous media to heterogeneous porous media, and by improving the reconstruction technique to include the cases where only drilling cuttings are available. The overall objective of the project is the determination of the transport properties of the porous media using the reconstruction technique and the discrete (network) analysis.
The proposed project, as an extension of the CARE project, aims to demonstrate a software tool that will expand the applicability of the initial product and will reduce the cost of petrophysical and reservoir data acquisition in two ways : First, it will minimize the need of core sample collection (reduction in drilling cost), since the drilling cuttings will be enough for the construction of a 'virtual sample' of the hydrocarbon bearing porous media. In addition, this feature offers great advantages for the cases that core sample are not available (soft formations, damaged cores, etc.). Second, the final product, after the extension of the analysis to heterogeneous and anisotropic porous media and the inclusion of the wettability effects, covers almost all the possible industrial situations, and thus minimizes the need of the costly experimental procedures for the acquisition of the required information. The methodology used for the reconstruction of the heterogeneous porous media from drill cuttings is based on the methodology used by the initial product. The present tool will analyse high-resolution back-scatter SEM images of the pore space to extract geostatistical information that is used to generate a reliable reconstruction of the complex rock-pore system in 3-D. The information content of the resulting data is equivalent to that contained inserial section data of pore casts. By partitioning the "virtual" pore structure to its constituents, it is then possible to obtain detailed 3-D geometrical and topological characterization of the pore space. Pore size distributions and network coordination numbers (connectivities) determined in this step are subsequently used as input to network simulators of single- and two-phase flow thus providing estimates of the petrophysical and reservoir engineering properties of interest.
