In some aspects, a number of subsystem models is accessed by a computer system. Each subsystem model represents dynamic attributes of a distinct physical subsystem in a subterranean region. At least one of the number of subsystem models represents dynamic attributes of a mechanical subsystem in the subterranean region. A discrete fracture network (DFN) model representing a fracture network in the subterranean region is accessed at the computer system. The DFN model includes junction models. Each junction model represents interactions between a respective set of subsystem models associated with the junction model. Junction variables of the junction model can be defined based on dynamic attributes of the respective set of subsystem models associated with the junction model. A stimulation treatment for the subterranean region can be simulated by operating the DFN model including the junction variables.

Estimate active-adjacent borehole interference severity

Номер: CA3103969C
Автор: Dinesh Ananda Shetty, Shahab Jamali, Srividhya Sridhar, William Owen Alexander Ruhle
Принадлежит: Halliburton Energy Services Inc

This disclosure presents processes to determine whether a leak-off event is occurring during the treatment stage of an active borehole. The leak-off event data, such as the severity or magnitude of the potential leak-off, can be communicated to other systems to adjust the treatment stage, the fluid composition, the fluid pressure, or the fluid flow rate. Diverter material can be added to the fluid. The monitoring of the leak-off event can occur over a time interval, such as the time of the treatment stage and periodic adjustments to the treatment stage can be implemented. The leak-off event can be identified when a fluid pressure slope indicates an overall increase in pressure in an adjacent borehole or if the amount of fluid entering an adjacent borehole exceeds a leak-off threshold.

Real time parent child well interference control

Номер: CA3097884C
Автор: Dinesh Ananda Shetty, Srividhya Sridhar, William Owen Alexander Ruhle
Принадлежит: Halliburton Energy Services Inc

When a child well is hydraulically fractured near the depleted reservoir volume surrounding a previously produced parent well, it is economically efficient to deliver proppant to the formation volume and fractures not reached by the parent well. A fracture length, which is the distance fluid travels from the child well to the depleted region, is calculated as a function of fracture stage. From identified trends in fracture length, fracture length for future stages can be predicted. Based on predicted fracture length, the slurry or treatment volume to cause well interference can be estimated. Proppant concentration or fracturing stage design can be adjusted so that the well interference volume is larger than the treatment volume and proppant is efficiently delivered to the child well fractures.

Real time parent child well interference control

Номер: US11753917B2
Автор: Dinesh Ananda Shetty, Srividhya Sridhar, William Owen Alexander Ruhle
Принадлежит: Halliburton Energy Services Inc

When a child well is hydraulically fractured near the depleted reservoir volume surrounding a previously produced parent well, it is economically efficient to deliver proppant to the formation volume and fractures not reached by the parent well. A fracture length, which is the distance fluid travels from the child well to the depleted region, is calculated as a function of fracture stage. From identified trends in fracture length, fracture length for future stages can be predicted. Based on predicted fracture length, the slurry or treatment volume to cause well interference can be estimated. Proppant concentration or fracturing stage design can be adjusted so that the well interference volume is larger than the treatment volume and proppant is efficiently delivered to the child well fractures.

Complexity index optimizing job design

Номер: CA3131425C
Автор: Dinesh Ananda Shetty, Harold Grayson Walters, Neil Alan STEGENT, Robert Douglas Hillard
Принадлежит: Halliburton Energy Services Inc

Selecting a fracing-plan-to-apply to optimize a complexity index includes identifying a set of controllable input variables that defines a fracing plan. Initial values for the set of controllable input variables are defined. The initial values of the set of controllable input variables are processed to produce an initial stimulated geometry. A complexity estimator is applied to the initial stimulated geometry to produce an initial complexity index, which is evaluated to identify at least one variation from the initial values, which is processed to produce a variation stimulated geometry for each of the at least one variation from the initial values. The complexity estimator is applied to the at least one variation stimulated geometry to produce a variation complexity index for each of the at least one variation from the initial values. The fracing-plan-to-apply is selected from among the initial values and the at least one variation from the initial values.

Принадлежит: Halliburton Energy Services Inc

Systems and methods generally relate to monitoring, evaluating, and controlling fracture geometry during a hydraulic fracturing operation, in real time. A method comprises measuring a signal representing a condition in a wellbore; inputting the signal into a model for estimating a dimension of a dominant fracture; determining the dimension of the dominant fracture; determining a target dimension for the dominant fracture; and minimizing a difference between the dimension of the dominant fracture and the target dimension in real time, by adjusting at least an injection pressure or flow rate of a hydraulic fracturing fluid into the wellbore.

A method of forming a sintered ζ-phase tantalum carbide can include assembling a particulate mixture including a tantalum hydride powder and a carbon source powder. The particulate mixture can be sintered to form a tantalum carbide having at least 70 wt. % of a ζ-phase with at least about 90% densification. After sintering, the tantalum carbide can be cooled to substantially retain the ζ-phase.

Higher order simulation of hydrocarbon flows of hydraulic fracture treatments

Номер: US09856726B2
Автор: Avi LIN, Dinesh Ananda Shetty, Uma Balakrishnan
Принадлежит: Halliburton Energy Services Inc

Higher order simulation of hydrocarbon flows associated with complex fractures produced in the hydraulic fracturing process in a well system may be used to obtain high fidelity results while minimizing a cost of computation. The higher order simulation of hydrocarbon flows may provide efficient and stable simulation algorithms that avoid any artificial boundary treatment inconsistent with the governing equations, while maintaining a uniform order of accuracy. In particular, a re-normalization technique implements higher-order finite difference/finite volume discretization near the boundary of the complex fractures. The simulation of hydrocarbon flows may be used to determine a production activity for the well system.

Принадлежит: Halliburton Energy Services Inc

In some aspects, a grid-point-spacing ratio is computed for a one-dimensional fluid flow model. The one-dimensional fluid flow model represents a flow path for well system fluid in a subterranean region, and the grid-point-spacing ratio is computed based on a parameter of the flow path. Grid points for the one-dimensional flow model are generated based on the grid-point-spacing ratio.
