Abstract:
Strain information may define strain of a material to stress. The strain of the material may be decomposed into classical strain, hysteretic strain, and residual strain. The classical strain, the hysteretic strain, and the residual strain may be used to facilitate modeling of the material. For example, the classical strain, the hysteretic strain, and the residual strain of a rock may be used to facilitate modeling of a subsurface region that includes the rock such as a reservoir simulation to predict hydrocarbon recovery.

Abstract:
A method is described for estimating seismic velocity from seismic data by training a neural network using a subset of a seismic dataset and the velocity model; estimating a second velocity model using the neural network and a second subset of the seismic dataset; and displaying the second velocity model on a graphical user interface. The method may be executed by a computer system.

Application number: 17/363,590

Abstract:
A disclosed pulsed-power drilling system may include a controller that receives and analyzes feedback from downhole components reflecting changing conditions or performance measurements associated with a pulsed drilling operation to determine that an operating parameter of the drilling operation should be modified. The controller may output a control signal to cause an adjustment of a configurable downhole component, such as mechanical, electrical, or hydraulic component that affects the operating parameter, while the drill bit remains in the wellbore. The controller may adjust a segmented transformer of a pulse-generating circuit, changing the number of primary winding switches that are fired, or the timing of the firing of the switches, to modify characteristics of the generated pulses. Adjusting a downhole component may affect the drilling rate, the drilling direction, the flow of drilling fluid, a pulse rise time, a pulse repetition rate, or a rate of penetration for the drilling operation.
