Abstract: The present invention is related to a method for reconstructing at least one trace in a seismic image of a common receiver and time domain, the image comprising traces in time domain with seismic data and one or more traces to be reconstructed. A first aspect of the invention is a method that is characterized by a specific use of a convolutional neural network trained under an unsupervised learning approach with a modified receptive field. A second aspect of the invention is a deblending method based on the use of a reconstructing method according to the first aspect of the invention applied to a denoising step of a deblending process allowing a very effective data acquisition while keeping a high quality output data sets after being processed according to the first and/or second aspects of the invention.

Abstract: A computer-implemented method for manipulating a mesh for the discretization of a reservoir domain, the reservoir domain modeled by a geophysical model, a fluid model, or both models. The method includes the use of cells partitioning the reservoir domain wherein each cell includes a numerical mesh. The mesh of the reservoir domain is the union of the meshes located in the plurality of cells. The partitioning of the domain into a plurality of cells allows easy modification of specific regions of the domain wherein re-meshing requirements are limited to those cells housing modified elements and maybe some surrounding cells.

Abstract: The present invention is related to a computer implemented method for manipulating a numerical model of a 3D domain, said numerical model comprising geometrical entities such as layers, fractures, discontinuities, facies, etc., being identified as geometrical entities because they can be defined by its shape. The resulting data storage block is very large. The management of such large data bases or data storage block may be unaffordable as simple operations over one or more geometrical entities require the processing of the entire data base. The method provides an efficient management of the data base by a set of specific lists of indexing keys increasing the speed of access, for instance for writing and reading operations, for one or more determined geometrical entities.

Abstract: A system, method and program product for managing hydrocarbon energy production. A hydrocarbon field modeler models physical characteristics of a hydrocarbon energy field. A load predictor predicts processing workload in modeling the hydrocarbon energy field, and identifying a balanced modeling unit distribution across multiple processors simulating field production. A load distribution unit distributes the modeling units across the processors for a balanced modeling unit distribution. The load predictor and load distribution unit proactively shifts loads to maintain workload balanced throughout the simulation.

Abstract: A method and computer program product for managing hydrocarbon field production, e.g., petro-chemical reservoir production. The hydrocarbon field is modeled using the finite volume method (FVM) model and the finite element method (FEM). Centroids are located in each FVM cell and each FEM element and overlapping cells are identified. After determining the distance between centroids for overlapping cells, fluid characteristics are mapped to the FEM element centroids, weighted inversely for distance between the respective centroids. A permeability/conductivity weighted average is determined for pore pressure and temperature of sub-volumes clustered around each FEM element node. Field production may be adjusted in response to FEM element node characteristics.
