Abstract: In an embodiment, a process may divide elements of a mesh into sub-elements utilizing field nodes. The process may determine if each field node is inside or outside a material point cloud. The process may calculate a distance from each outside field node to a surface of the material point cloud based on a surface vector in a normal direction and a deformed volume of a material point. The process may calculate a distance from each inside field node to the surface of the material point cloud based on a surface vector, in a normal direction and associated with an outside field node closest to the inside field node, that takes into account a deformed volume of a material point. The process may utilize the distances to generate a signed distance field that may be used to perform calculations to simulate a behavior of a physical material/object that exhibit deformations.

Abstract: A geomechanically integrated model of stimulated rock volume (SRV) of subsurface formations in an area of interest for hydrocarbon production is formed. The methodology for forming the model takes into account geomechanical effects of interest and potential significance which occur over different dimensional scales. The methodology incorporates into the model fault perturbations which are present at a regional or seismic scale of from hundreds to thousands of meters, as well as layer stress occurring at a much smaller hydraulic fracture simulation scale of fractions of meters or meters. The methodology accommodates the differing representations of the subsurface grids used in previous models to represent these different geomechanical effects. Complex grid meshing and computer processing are avoided, improving computer operation and saving computer processing time.

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: Systems and methods are provided for managing power usage in mining environments. The amount of power needed to operate a set of electrical machines that are to run simultaneously is determined. Power usage by the electrical machines during a time period can be predicted based on how much power is expected to be needed by each machine. If the predicted power usage exceeds a threshold power usage, power to one or more electrical machines in the mining environment is restricted so that actual power usage in the mining environment does not exceed the threshold power usage during the specified time period. The electrical machines which will have power restricted thereto can be selected based at least in part on relative priorities for the electrical machines in the set. Power can be restricted to machines as a whole (an effective shutdown), or to specific operations of the machines.

Abstract: Methods for determination of surface leak rates in an injection well after determining a presence of a surface leak based on visual identification of a leak typically associated with abnormal decrease in surface injection pressure. An injection well performance model is generated based on a reservoir pressure of the injection well, a fluid injection pressure, and properties of an injection fluid. The injection well performance model is calibrated using a shut-in bottomhole pressure and injection data measured prior to the determining of the presence of the surface leak. A production well model is generated from the injection well performance model. For each pressure value between the pressure of the injection well measured at the surface and a shut-in wellhead pressure (SIWHP), the production well model is executed to determine a flow rate of the surface leak.
