Abstract: A method of simulating a production process on the basis of a continuous fluid model with discrete time evolution is described. The method of simulating makes use of assigning production and processing resources of various stations of the fluid model to various fluids with respect to a priority identifier of the fluids. Division of the station resources to various fluids is further based on a momentary amount of the various fluids. Based on the assignment of the station resources to the various fluids, the time evolution of the fluid amounts are determined without having to perform time and resource consuming optimization. Additionally, assignment of station resources can be manually and temporarily modified by a fluid manipulation means allowing for a universal and dynamic modification of the behavior of particular stations without interrupting or affecting the entire simulation process.

Abstract: The invention relates to a method for determining the zones of a stratified porous medium whose physical properties are known, wherein the front or interface between fluids in place and injected flushing fluids moves in a stationary manner, without using a complete flow simulation. Starting from an a priori defined front form which separates two zones of uniform saturation, assumed to have a stationary displacement, the pressure field is determined independently in each zone. The pressure jump on either side of the front is then evaluated for any point of the interface. If it is zero, the form of the front is such that it can move in a stationary manner in the medium. If the pressure jump is not zero, the user deforms the interface and resumes the process until a stationary form is obtained. This process may not converge. In this case, we consider that a stationary front cannot form through the total thickness of the medium and the medium is divided so as to seek solutions in intermediate zones.

Abstract: A process for constructing a three-dimensional geologic model of a subsurface earth volume wherein resolution scales of multiple diverse data types, including seismic data, are accounted for by generating multiple frequency passband models and combining them together to form the complete geologic model. Preferably, a model is generated for each of a low-frequency passband, a mid-frequency passband, and a high-frequency passband. When integrating seismic data into the modeling process, the seismic-frequency passband constitutes the mid-frequency passband model. The process further contemplates updating tentative frequency-passband models through optimization of assigned rock property values in each tentative model according to specified geological criteria. Such optimization is carried out by perturbation of the rock property values in a manner wherein the frequency content of each model is maintained.

Abstract: The invention allows construction of the architecture of sedimentary layers deposited on a topographic surface as a result of the passage of sedimentary currents, using cellular automata. The topographic surface is discretized into a set of cellular automata. Then, for each current and each automaton, a stationary physical state resulting from an iterative process wherein intermediate physical states are constructed by material and energy exchanges between the automata is determined. These automata are thus constructed so as to be representative of the action of the sedimentary currents on the construction of the sedimentary architecture. A set of geologic variables allowing the architecture of the sedimentary layers to be reconstructed is thus deduced from these stationary physical states. Preferred fields of application of the method are oil exploration and production and reservoir characterization.

Abstract: The present invention is a method and system for simulating fluid flow in a cavity, having relevance to the modeling of viscous flows within thin cavities of complex shapes in which heat exchange with the cavity walls may be a governing factor, as in injection molding of plastic parts. Its automated discretization scheme, in which the model cavity is partitioned into macrocells, each macrocell having substantial contact areas with the model cavity walls, eliminates the need for time consuming and expensive manual model configuration required by some modeling methods.
