In this paper we describe a new method to obtain estimations of the geostatistical parameters (GPs) such as the correlation length, lc and the permeability variance sigma2 ln from well test data. In practical studies, the GPs are estimated using geol

Summary Reservoir engineers often have to deal with history-matching problems. This is time-consuming because of the many numerical simulations that have to be run and also because of the size of the models. Optimization, coupled with gradient-based

Detailed reservoir models routinely contain 106–108 grid blocks. These models often cannot be used directly in a reservoir simulation because of the time and memory required for solving the pressure grid on the fine grid. We propose a nested griddi

Advances in computer power and in reservoir characterization allow simulation of pressure transients in complex reservoirs generated stochastically. Generally, interpretation of these transient gives useful information about the reservoir hydraulic p

We have devised a renormalization scheme which allows very fast determination of preferential flow-paths and of up-scaled permeabilities of 2D heterogeneous porous media. In the case of 2D log-normal and isotropically distributed permeability-fields,

The gradual deformation method (GDM) is a geostatistical parameterization technique that generates a sequence of realizations evolving smoothly while preserving the statistical characteristics of the model. Combined with an optimization algorithm, it

We develop a general methodology for history matching that uses the method of local deformation and streamline-based simulation. We generate a geostatistical realization that can obey constraints at wells and other geological information. The history

Geostatistical models provide detailed geostatistical images of the reservoir containing several millions of gridblocks. Reservoir engineers often have to deal with history matching problems: they have to find images that honor production data. This

We attempt to reconstruct the kinematics (deformation and motion) of the Western Alpine Arc between the Mercantour and Aar Massifs. First, we compile a map showing principal extension (X) direction within three major structural units. In the external
