Abstract: A method of developing a petroleum reservoir from a reservoir model constrained by the production data and seismic attributes. Production data and seismic data are acquired during the development of the reservoir. A first image of a seismic attribute is constructed from the seismic data. Production responses are simulated from a reservoir model using a flow simulator. An image corresponding to the seismic attribute is simulated from the reservoir model. A local dissimilarity map is constructed from the reference seismic attribute image and from the simulated seismic attribute image. The reservoir model is modified to minimize any difference between the measured production data and the corresponding production responses and to minimize local dissimilarities. This model is used to determine an optimal development scheme and the reservoir is developed according to the development scheme.

Abstract: A method of improving a geologic model of a subsurface region. One or more sets of parameter values are selected. Each parameter represents a geologic property. A cost and a gradient of the cost are obtained for each set. A geometric approximation of a parameter space defined by one or more formations is constructed. A response surface model is generated expressing the cost and gradient associated with each formation. When a finishing condition is not satisfied, at least one additional set is selected based at least in part on the response surface model associated with previously selected sets. Parts of the method are repeated using successively selected additional sets to update the approximation and the response surface model until the finishing condition is satisfied. Sets having a predetermined level of cost to a geologic model of the subsurface region and/or their associated predicted outcomes are outputted to update the geologic model.

Abstract: A method for processing seismic data. The method includes performing a plurality of stochastic simulations for one or more rock model parameters to generate one or more anisotropic parameters for a subsurface area of the earth.

Using the joint multi-dimensional probability density functions and measured well log data, the method computes one or more posterior probability density functions. The method then includes deriving one or more anisotropic profiles from the posterior probability density functions and generating a seismic image from the anisotropic profiles.

Abstract: A method of modifying a geological model representative of an underground reservoir is disclosed which respects average proportions of the lithologic facies imposed by a production data calibration process which has application to petroleum reservoir development. A geographical zone Z is defined within the geological model and an average proportion in zone Z allowing the production data to be calibrated is determined for k facies, with an optimization process. The proportions of these facies are modified using a block indicator cokriging method constrained by the average proportions to be respected. A new geological model constrained by the modified facies proportions is simulated and the development of the underground medium is optimized by the simulated model.
