Abstract
Set against a background of large uncertainties connected with reservoir description and subsequent recovery evaluation of offshore hydrocarbon fields, a requirement for improved reservoir modelling techniques has become evident. This paper presents a computer program, SESIMIRA, that uses bit-matrices to create high-resolution three-dimensional grids for the three-dimensional modelling of heterogeneous reservoirs. The main objective of the program is to generate reservoir models that clearly preserve a realistic heterogeneity and adequately represent the distribution of important reservoir parameters. The reservoir modelling procedure is applicable to any type of geological setting. The concept is based on the integration of sedimentological, structural and petrophysical data that can be treated both deterministically and stochastically. The user has the option of including any number of facies types, and can require that different conditions (rules) are fulfilled during the modelling process. The current version of SESIMIRA utilizes a Boolean approach to create facies bodies in the reservoir model.
