Patent number: 11954791Abstract: Approaches in accordance with various embodiments provide for fluid simulation with substantially reduced time and memory requirements with respect to conventional approaches. In particular, various embodiments can perform time and energy efficient, large scale fluid simulation on processing hardware using a method that does not solve for the Navier-Stokes equations to enforce incompressibility. Instead, various embodiments generate a density tensor and rigid body map tensor for a large number of particles contained in a sub-domain. Collectively, the density tensor and rigid body map may represent input channels of a network with three spatial-dimensions. The network may apply a series of operations to the input channels to predict an updated position and updated velocity for each particle at the end of a frame. Such approaches can handle tens of millions of particles within a virtually unbounded simulation domain, as compared to classical approaches that solve for the Navier-Stokes equations.Type: GrantFiled: May 23, 2022Date of Patent: April 9, 2024Assignee: Nvidia CorporationInventors: Evgenii Tumanov, Dmitry Korobchenko, Alexey Solovey

Patent number: 11053789Abstract: Estimating a production prediction of a target well includes computing, based on production time series from training wells, a smoothed production history curves. Each smoothed production history curve corresponds to a training well. Based on the smoothed production history curves, a fitting function defined by a set of fitting coefficients is selected. A machine learning process determines, based on a set of well parameters for each training well, a set of predicted fitting coefficients as a function of a set of well parameters of the target well. Estimating the production prediction further includes applying the predicted fitting coefficients to the fitting function to compute a production prediction curve for the target well, and presenting the production prediction curve.Type: GrantFiled: December 29, 2016Date of Patent: July 6, 2021Assignee: Schlumberger Technology CorporationInventors: Gabriel Maher, Daniel D'Souza

Patent number: 11009001Abstract: The invention relates to the field of hydropower scheduling, and relates to a method for multi-objective optimal operations of cascade hydropower plants based on relative target proximity and marginal analysis principle. The invention constructs an optimization model with relative target proximity by introducing positive and negative ideal points of objectives so that a multi-objective optimization is efficiently handled. A strategy for processing complex operation constraints is proposed and coupled with genetic algorithm to solve the model. Thus, optimal solution sets under different weight coefficients of objectives can be determined. Following this, marginal benefit and marginal cost are introduced to represent a relationship between multiple objective values and corresponding weight coefficients.Type: GrantFiled: December 22, 2017Date of Patent: May 18, 2021Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Jianjian Shen, Juntao Zhang, Chuntian Cheng, Wenjing Niu
