  • Publication number: 20200234163
    Abstract: A method of data room content evaluation and a computer program product therefor. Valuation inputs indicate contents expected to be determined in a data room visit. A score range is selected for each valuation input and prior models are elicited. Conditional probabilities for a likelihood model are estimated interactively. Using estimated conditional probabilities the value of a visit or visits are calculated for subsequent analysis. Then, the value of data room visits may be determined by interactively analyzing estimated conditional probabilities.

  • Patent number: 10571603
    Abstract: The object of the invention is a method implemented in a computer for the numerical simulation of a porous medium that may comprise multiple interacting hydraulic fractures in continuous or naturally fractured medium. The method calculates numerically the propagation of a crack, or set of cracks, for instance under the fluid pressure imposed artificially through a well or perforation in a rock mass. This is accomplished by using the Finite Element Method and the special elements named zero-thickness interface or joint elements in the specialized literature, which are pre-inserted along all potential crack paths in the rock mass (pre-existing natural and artificial fractures plus main potential new fracture paths).

  • Patent number: 10176538
    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.
