  • Patent number: 11126762
    Abstract: A data processing system is provided which determines the migration of oil and gas by a basin simulation section and predicts future reservoir performance from current reservoir production measures. The data processing system provides more accurate reservoir rock and fluid property distribution in reservoir locations between well locations where such attributes cannot be measured. The data processing system operates based on physical realities captured from migration by the basin simulation section. The data processing system differs from conventional methods, which use measurements obtained at the wells and interpolate between for regions between the wells using statistical techniques. Results from the data processing system shed more light into reservoir discontinuities among the wells, and yield better distribution of hydrogen sulfide, tar zones (Heavy Oil) within the reservoir.

    Abstract: Earth models of stress conditions in subsurface reservoirs are formed reflecting rock mechanical properties, stress regime and also wellbore stability. A number of variables related to the rock mechanical properties and stress conditions are parameterized. The variability of minimum horizontal stress magnitudes as a product of the relative contributions of the various rock properties and input parameters or variables used to form the model is analyzed. Differences between predicted minimum horizontal stress magnitudes in the formation and an actual measurement obtained from the formation (for example, fracture closure pressure) are determined. The determined differences are the minimized through an optimization methodology to find a best set of parameters suitable to match the minimum horizontal stress to actual formation measurement.

  • Patent number: 10968724
    Abstract: The selection of a candidate formation realization(s) from a plurality of formation realizations may be done with a classification and regression tree (CART) analysis taking into account petrophysical and geological properties. For example, a method may include applying a CART analysis to a plurality of formation realizations using a first formation property as a predictor in the CART analysis, wherein the plurality of formation realizations are for a second formation property and are based on at least one measured formation property, thereby yielding an association between the first and second properties for each of the plurality of formation realizations; analyzing a strength of the association for each of the plurality of formation realizations; and selecting a candidate formation realization from the plurality of formation realizations based on the strength of the association. The identified candidate formation realization(s) may then be used to develop the parameters of subsequent wellbore operations.

  • Patent number: 10954757
    Abstract: An illustrative domain-adaptive hydraulic fracturing simulator includes: a data acquisition module, a simulator module, and a visualization module. The data acquisition module acquires measurements of a subterranean formation undergoing a hydraulic fracturing operation. The simulator module provides a series of states for a model of the subterranean formation by: (a) constructing said model from the measurements, the model representing said current state throughout a modeled domain; (b) determining a core domain of influence within the modeled domain by identifying active fractures; (c) generating a linear set of equations to derive the subsequent state from the current state, the linear set of equations including fluid flow equations for the core domain of influence and excluding fluid flow equations for a region of the modeled domain outside the core domain of influence; and (d) deriving the subsequent state from the linear set of equations. The visualization module displays the series of states.

    Abstract: The present invention relates to a method and corresponding system for generating a computer-aided design (CAD) model from a finite element mesh. The method of the invention begins with selecting one or more mesh-element-faces on a finite element mesh that represents a geometric object to be formed of one or more geometric faces. Next, from the one or more selected mesh-element-faces, respective geometric faces are generated. Finally, any generated geometric faces are stitched together to make a geometric shell of the geometric object that the finite element mesh represents.

    Abstract: Method and system for optimizing production from an oil and gas reservoir includes selecting a geocellular grid representing at least one property of the reservoir, defining a data range for the property that reflects uncertainty regarding which values may be used for the property, defining a first reservoir simulation model, simulating production from the reservoir with the model using the at least one property, comparing the output of the simulated production from the reservoir with a predetermined criteria based on historical data, and modifying the property to a different value within the data range for the property if the predetermined historical criteria is not met. These steps may be repeated for at least two values for the property within the data range. The above may be repeated for a second reservoir model and the outputs of the simulated production for the models may then be ranked according to predefined criteria.

  • Patent number: 10929578
    Abstract: A mechanism is provided in a data processing system for minimizing uncertainty envelopes in trajectories of evolving ensemble members. The mechanism generates a trajectory forecast of each member object of an ensemble based on an initial state-space and a model for predicting trajectories of the member objects to generate a plurality of trajectory forecasts. Each of the plurality of trajectory forecasts has an individual uncertainty envelope. The mechanism applies a classification algorithm on the plurality of trajectory forecasts to identify at least one group of member objects having similar trajectory forecasts, generates a reduced ensemble of member objects including the identified group of member objects, and reconfigures the state-space and the model for predicting trajectories. The mechanism generates an updated trajectory forecast of each member object of the reduced ensemble based on the reconfigured state-space and the reconfigured model for predicting trajectories of the member objects.
