Abstract: An example real-time simulation framework for a fluid and granular substance mixture is disclosed. Such a framework may be based on modeling height fields and horizontal velocities of different material phases, which in the context of a water-sand system, may include sand, water, and mixed water. The framework achieves a trade-off between simulation fidelity and performance, providing real-time computation for interactive applications. The example framework formulates the external frictional force and elastoplastic internal force of sand based on horizontal grid and further handles the water/sand coupling via diffusion and momentum exchange. The time updates for the simulation is efficiently performed using a semi-implicit operator splitting discretization scheme and an asynchronous scheme for the fluid and the granular substance.

Abstract: Techniques for simulating fluid flow using a lattice Boltzmann (LB) approach for solving scalar transport equations and solving for total energy are described. In addition to the lattice Boltzmann functions for fluid flow the techniques include modifying a set of state vectors of the particles by adding specific total energy to states of particles that will be advected and subtracting the specific total energy from states of particles that will not be advected over a time interval and performing advection of the particles according to the modified set of states.

Abstract: In some embodiments, the disclosure is directed to a system for simulating multiple components and phases for fluid phase detection. In some embodiments, the system is configured to execute fast iterations under given temperature, pressure, and feed, with liquid phases starting from 100% purity of a corresponding key component. In some embodiments, the system is configured to apply a direct substitution method with relaxation damping for iterations at fixed conditions. In some embodiments, the system is configured to draw a tangent plane from a suspicious phase composition and execute a tangent plane distance analysis at a potentially missed physical phase by estimating 95% to 99.9999% purity of a possible liquid key component. In some embodiments, the system is configured to automatically correct the order of key components for simulations, based on analyses such as tangent plane distance analysis, immiscibility checks, and the exclusion of Henry components.

Abstract: Systems and methods include a computer-implemented method: Historical and forecasted field life data for existing gas wells is received, including pressure and temperature data at different depths of the existing gas wells over the life of the existing gas wells. Using the historical and forecasted field life data for the existing gas wells, a sub-erosion production rates model is generated for in situ estimation of sub-erosion for gas wells. Well parameters for a subject gas well are received. Using the well parameters of the subject gas well, the sub-erosion production rates model is executed to identify high-erosion risk spots in the subject gas well, including using iteratively evaluating results using three different methods. Outputs of the sub-erosion production rates model are provided for presentation to a user in a graphical user interface (GUI).

Abstract: A method for simulating fluid surfaces in real-time in response to user input includes detecting interactive conditions triggering insertion of a heterogeneous mesh sequence in a 3D model sequence for rendering, fetching ones of the heterogenous mesh sequence from a computer memory, inserting the successive members in corresponding representations of the 3D model sequence in a computer memory, and rendering successive video frames from the representations of the 3D model sequence each including a successive member of the heterogenous mesh sequence. A related method for generating a compact heterogeneous mesh sequence for use in rendering corresponding frames of video includes generating a heterogenous mesh sequence modeling response of a fluid surface to physical forces, the heterogenous mesh sequence characterized by position values represented in computer memory by not less than 12 bytes for each vertex thereof, transforming the heterogenous mesh sequence into the compact heterogeneous mesh sequence, at least in part by quantizing the position values to not greater than four bytes, and storing the compact heterogeneous mesh sequence in a computer memory for use in real-time rendering.

Abstract: Differential equations defining physics of a reservoir are modeled as a neural network. Measured data for the reservoir is used as boundary condition to calculate the different equation parameters. The result is a neural ordinary differential equation network that models reservoir characteristics (e.g., inter-well connectivities, response times for injection wells and production wells) using physics that are encoded into the network. The neural ordinary differential equation network provides a solution for the reservoir that is constrained by the physics of the reservoir.

Abstract: A method may include obtaining grid model data for a geological region of interest and well data for various wells in the geological region of interest. A well among the wells may correspond to a simulated well network in a reservoir simulation. The method may further include determining, based on the grid model data and the well data, a first simulation solution for a first constraint rate equation decoupled from the simulated well network and using a first search method. The method may further include determining, based on the grid model data, the well data, and the first simulation solution, a second simulation solution for a second constraint rate equation coupled to the simulated well network and using a second search method. The method may further include performing, based on the grid model data, and the second simulation solution, the reservoir simulation.
