  • Patent number: 9874086
    Abstract: A system for building a geological model of oil or other mineral deposit. In particular, the system allows the coefficients of correlation to be determined for a set of well-logging curves and marker depth positions to be established for which the values of correlation coefficient are maximal. A technical result is the improvement of the accuracy of evaluating the parameters that are used to construct a geological model of location of oil or other deposits. The system makes it possible, given a marker, which already has its marks in a group of wells, which is referred to as reference group, to calculate such marks for wells from another group. For any well W where the marker depth is to be determined, wells from the reference group are chosen lying within the specified distance from the well W, and a well with the maximal coefficient of correlation is chosen among them.

  • Patent number: 9733373
    Abstract: The invention generally relates to methods of modeling and building models of oil-and-gas deposits. More particularly, the invention relates to a computer-implemented method, a computerized system, and a computer-readable medium designed for automated identification of surfaces for building a geologic-hydrodynamic model of an oil and gas deposit based on seismic data. A technical result is the improvement of the accuracy of building a geological-hydrodynamic model of an oil-and-gas deposit. The objective of embodiments of the invention is to provide a method, device, and a non-transitory computer-readable medium designed for the implementation of stages accounting for a considerable part of the entire problem of building a geological-hydrodynamic model, namely, automated (that is, requiring the user to participate only in the stage of initial data input) building of a set of surfaces based on input seismic data.

  • Patent number: 9664033
    Abstract: System for building a geological model of oil or other mineral deposit. The system determines functionals represented by the sum of coefficients of correlation for a set of well log curves. A technical result is the improvement of the accuracy of evaluating parameters that are used to build geological model of the location of oil or other deposits. The system makes it possible, given set of markers, chosen as initial solution and to calculate their depths at each well to ensure the best total correlation. For any marker in the set, functional is determined, represented by the sum of correlation coefficients for the set of well log methods for pairs of wells located within specified distance from one another. Partial derivatives are evaluated for this functional, and the vector thus obtained is smoothed and used to search for a larger value of the functional within certain segment along this vector.

In particular, the utility model relates to systems designed for automated identification of surfaces for building a geologic-hydrodynamic model of an oil and gas deposit based on seismic data. A technical result is the improvement of the accuracy in building a geological-hydrodynamic model of an oil-and-gas deposit. The objective of this utility model is to provide a system designed for building a geological-hydrodynamic model, in particular, automated (that is, requiring the user to participate only in the stage of initial data input) construction of a set of surfaces based on input seismic data. The output surfaces can be used, without additional processing, to construct a geological-hydrodynamic grid. The input data for the system are volumes of seismic data attributes P, Q; and seismic volume (optional).
