  • Patent number: 10810330
    Abstract: A method of performing aspects of an energy industry operation includes receiving input data at a processing system, the input data describing an assembly for performing the energy industry operation and properties of the formation, the assembly including a downhole component, the processing system configured to estimate production properties based on mathematical models including at least a model of the downhole component and one or more models for simulating fluid flow in the formation. The method also includes, based on the input data, generating a workflow that includes steps for estimating production properties using the models, receiving a selection from a user specifying a type of analysis to be performed and/or a level of complexity of analysis to be performed, customizing the workflow based on the user selection, estimating the production properties based on the models, where estimating is performed according to a procedure specified by the workflow.

  • Patent number: 10345764
    Abstract: A method of performing aspects of an energy industry operation includes simulating an energy industry operation parameter by an analysis module, wherein simulating includes predicting values of the operational parameter via one or more mathematical models of the assembly and a formation region, and estimating an uncertainty range of at least one of the input data and the predicted values of the operational parameter; generating a performance envelope based on the predicted values and the uncertainty range; generating an operating envelope by the analysis module, the operating envelope prescribing minimum constraints on the operational parameter; during the energy industry operation, receiving real time measurements of the operational parameter by a production performance module, and comparing the measured operational parameter to the operating envelope and the performance envelope; and based on the measured operational parameter being outside the performance envelope, controlling the energy industry operation

  • Publication number: 20160040513
    Abstract: A method of estimating saturation conditions of reservoir brines in an underground reservoir includes: receiving data representing a temperature of the brine; determining if the temperature is greater than a preset value; and selecting either a first method or second method, different than the first method, of calculating the saturation conditions based on the determination. The first method is selected when the temperature is greater than the preset value and the second method is selected when the temperature is less than the preset value.

  • Publication number: 20160040532
    Abstract: A method of estimating properties of a reservoir fluid in an underground reservoir includes: calculating the density ? of the mixture containing water; determining component-specific volume shift parameters ci; replacing the component specific volume shift parameter for water with a volume shift parameter cH2O; determining a total volume shift c required from the sum of the component specific volume shifts and the mole fraction of each component in the mixture; determining a corrected molar volume of the liquid and vapor by subtracting the total volume shift c from an equation of state (EOS) calculated molar volume v; and recalculating density ? and compressibility factor Z for the liquid and vapor phases with the corrected molar volume.

  • Publication number: 20160041142
    Abstract: An apparatus for estimating conditions of reservoir fluid in an underground reservoir that includes a sensor for measuring one or more measured parameters of that fluid, the measured parameters including at least one of: temperature, pressure and density of the fluid and a processor. The processor is configured to: receive data representing the one or more measured parameters; determine or receive coefficients for an extended corresponding states (XCS) model, wherein propane is used as a reference fluid in determining the coefficients or was used in the forming of the received coefficients; and solve the XCS model with the coefficients to form estimates of the fluid conditions.
