    Abstract: A system for notching a target wellbore in a subsurface formation includes a notching tool and a wellbore modelling system in communication with the notching tool. The wellbore modelling system includes a simulated notch, a simulated wellbore, a computational mesh, and a data processor. The simulated notch and the simulated wellbore are digitally positioned in the computational mesh of the wellbore modelling system. The simulated notch extends from the simulated wellbore. The data processor is communicatively coupled to the simulated notch, the simulated wellbore, and the computational mesh, and is operable to execute an iterative process. The wellbore modelling system is configured to communicate the target notch shape, the target cutting depth, or both, to the notching tool for notching the target wellbore with the target notch shape, the target cutting depth, or both.

    Abstract: This specification describes a simulation system that performs simulations of physical environments using a graph neural network. At each of one or more time steps in a sequence of time steps, the system can process a representation of a current state of the physical environment at the current time step using the graph neural network to generate a prediction of a next state of the physical environment at the next time step. Some implementations of the system are adapted for hardware GLOBAL acceleration. As well as performing simulations, the system can be used to predict physical quantities based on measured real-world data. Implementations of the system are differentiable and can also be used for design optimization, and for optimal control tasks.

    Abstract: The invention discloses a full wellbore pressure calculation method, device and computer-readable storage medium for fracturing horizontal wells, includes steps: collect basic parameters, establish fully implicit numerical model of formation flow; solve the full implicit numerical model under an inner boundary condition of a constant gas production rate; calculate wellbore pressure change of each fracturing section of horizontal well; calculate the bottom-hole pressure of each fracture initiation point; repeat steps until the variables converge, the bottom-hole flow pressure and the bottom-hole pressure at each fracture initiation point are obtained at this time step; the wellbore pressure and wellhead casing pressure are calculated at this time step. The method is for predicting the variation law of full wellbore pressure and wellhead casing pressure by using production data in the absence of bottom-hole pressure test data, and has practical value for accurate prediction of production performance of gas reservoir fracturing horizontal wells.

    Abstract: An estimated gas leak flow rate can be determined using a teaching set of concentration profiles, a regression model implemented by a machine-learning subsystem, and a subset of attributes measured within an environment. The teaching set of concentration profiles can include gas flow rates associated with relevant attributes. The regression model can be transformed into a gas leak flow regression model via the machine-learning subsystem using the teaching set. The subset of attributes measured within the environment can be applied to the gas leak flow regression model to determine other attributes absent from the subset of attributes and an estimated gas flow rate for the environment. A gas leak attenuation action can be performed in response to the estimated gas flow rate.

    Abstract: A sewage pipe network real-time simulation method based on water supply Internet of Things data drive. The method involves an offline module and a real-time online module, wherein the offline module integrates a sewage pipe network model and a water supply pipe network hydraulic model, corrects historical water consumption of each node of the water supply pipe network hydraulic model, establishes a correction single-objective optimization model of the sewage pipe network model, and determines a transfer coefficient between the water consumption of each node and an inflow of an inspection well; and the real-time online module realizes the real-time simulation of hydraulic parameters of the sewage pipe network model. The method fills a vacancy in the field of sewage pipe network real-time simulation, and important technical support is provided for the management of sewage pipe network systems, and the method has good value in promotion and practical engineering application.

    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.
