摘要： The invention relates to a method having applications for oil exploration and CO2 storage of determining the three-dimensional distribution of the absolute permeability of a heterogeneous sample. The method includes: determining a 3D porosity map of the sample; carrying out a viscous miscible displacement experiment during which the evolution of the differential pressure on either side of the sample is determined; from this evolution, determining a 1D absolute permeability profile along the sample and constructing a first 3D permeability map from the 3D porosity map; estimating a simulated differential pressure by simulating numerically a viscous miscible test from the first permeability map and from the 1D permeability profile; determining the three-dimensional distribution of the absolute permeability of the sample by modifying at least once the first permeability map so as to minimize the difference between the simulated differential pressure and the differential pressure measured over the course of time.

A geologic model, from which seismic data are simulated in depth, is constructed in depth. The geologic model is made consistent with seismic measurements acquired in time by minimization of an objective function by comparing the seismic measurements with seismic data simulated from the geologic model and converted to time.

摘要： The invention is a method for real-time updating of a geological model using dynamic data while maintaining the coherence thereof with static observations. An initial set of reservoir property maps, obtained from stochastic simulations of a random function, are available. Parameters providing new realizations of the random function when applied to the set are selected. New maps are created using initial values of the parameters. As soon as new dynamic data are available, the parameters are modified to reduce a difference between the simulated data for perturbed models and the measured data. Finally, the reservoir is developed using a modified development scheme to account for the deformed maps.

摘要： The invention is a method of developing a petroleum reservoir employing a technique for selection of the position of the wells to be drilled. A production indicator map is utilized comprising a set of cells each associated with a production indicator defining impact on fluid production of addition of a well in this cell. The production indicator map is constructed by selecting cells from among the set of cells of the map; determining production indicators in the selected cells; and interpolating the production indicators on the set of cells of the map, by an interpolation model accounting for a distance between the cell to be interpolated and the closest well to the cell to be interpolated. The position of the well to be drilled is defined by the cell where the production indicator is a maximum.

摘要： Method for optimizing the development of an underground reservoir, wherein a geological model is updated using dynamic data and well tests.A reservoir model is constructed by performing a geological model scale change. Dynamic data are simulated from this reservoir model. Influence zones are identified within the geological model where the well tests induce a pressure variation during well testing. Well tests are then simulated for each influence zone. An objective function measuring the difference between the simulated data and the measured data is calculated. The geological model is then modified so as to reduce to the maximum the objective function using a geostatistical parametrizing technique. Finally, development of the underground reservoir is optimized by evaluating, by means of a flow simulator, the reservoir production for various production schemes.Application: notably oil reservoir development.
