E21B 33/03

Abstract:

An apparatus includes a valve coupled to a pressure-containing component of a wellhead assembly. The pressure-containing component can include a hollow body, a bore within the hollow body, and an access passage that is in the hollow body and is in fluid communication with the bore. The valve can include a sealing element that is positioned along the access passage and is selectively moveable between closed and open positions to control fluid flow through the access passage. During operation, the sealing element may be moved between the closed and open positions without actuating the sealing element through an outer end of the access passage. Additional systems, devices, and methods are also disclosed.

Abstract:

Fracturing systems with frac valves for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a bore to convey fracturing fluid, a seal disposed within the bore, and an actuator coupled to control movement of the seal. The actuator can be disposed within the bore so as to move the seal between a closed position in which the seal blocks fracturing fluid flow through the bore and an open position that allows fracturing fluid flow through the bore. Additional systems, devices, and methods for fracturing are also disclosed.

International Classification:

G06F 30/20
G06F 30/17
G06T 7/00

Abstract:

A virtual integration test system includes a computer configured to receive data indicative of measured dimensions of as-built components. The computer is also configured to perform a motion mechanics simulation on at least two deformation-uncritical components of the as-built components and perform a deformation mechanics simulation on at least one deformation-critical component of the as-built components. The motion mechanics simulation and the deformation mechanics simulation are performed concurrently within a simulation environment. In addition, the computer is configured to determine interface and integration compatibility of the as-built components based on the motion mechanics simulation and the deformation mechanics simulation, and to output an output signal indicative of the interface and integration compatibility of the as-built components.

Abstract:

Fracturing fluid delivery systems having components with sacrificial liners or sleeves are provided. In one example, a fracturing system includes a flexible fracturing fluid conduit coupled to a wellhead assembly. The flexible fracturing fluid conduit includes a flexible body, a rigid end joined to the flexible body, and a bore extending through the flexible body and the rigid end for conveying fracturing fluid to the wellhead assembly. The flexible fracturing fluid conduit also includes a rigid sacrificial sleeve installed in the rigid end and within the bore. In another example, a fracturing system includes a fracturing fluid delivery apparatus coupled to a wellhead. The fracturing fluid delivery apparatus includes a pressure-containing component having a rigid body with a bore for conveying fracturing fluid. The pressure-containing component has a sacrificial liner provided through the bore along an interior surface of the rigid body. Additional systems, devices, and methods are disclosed.

F16K 3/30

Abstract:

Fracturing systems with frac valves having gates for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a cavity transverse to a bore. A gate is positioned in the cavity and is movable between open and closed positions to selectively block flow through the bore. The gate includes a seal assembly positioned to seal against a sidewall of the cavity to surround the bore and block flow through the frac valve when the gate is in the closed position. The seal assembly can be actuated between a less-energized state and a more-energized state following movement of the gate within the cavity from the open position to the closed position. Additional systems, devices, and methods for fracturing are also disclosed.
