Abstract: What is described is a system and method for offline cementing of a casing hanger and a casing placed in a wellbore of a well. The system includes an isolation sleeve/cementing spool that is configured for engaging the casing hanger, where the isolation sleeve has at least one access port in fluid communication with an annulus formed by the casing in the wellbore. A dummy hanger is housed within the isolation sleeve and is configured for coupling with the casing hanger and is further in fluid communication with the casing. A valve is configured for coupling to the isolation sleeve and is configured to be in fluid communication with the dummy hanger. A quick connector is coupled to the valve and enables quick coupling of a cementing head.

Abstract: This disclosure presents a latch back pressure valve for use with a wellhead assembly. The latch back pressure valve includes a body and at least one seal extending circumferentially around the body. A plurality of extendable latches are supported by the body and configured to engage with corresponding locking grooves. A poppet is configured to be displaced to open a passageway through the body. A hold-down ring is configured to engage a miming tool such that rotation of the miming tool causes the plurality of extendable latches to an extended position.

Abstract: A system for delivering hydraulic fracturing fluid to a wellbore is provided. The system includes a first frac tree connected to a first wellbore and a second frac tree connected to second wellbore. The system further includes a zipper module and a first single straight-line connection between the zipper module and the first frac tree. The system also includes a second single straight-line connection between the first frac tree and the second frac tree.

Abstract: An annular seal for installation in an annular groove defined at an interface between first and second wellhead component is disclosed. The seal has an annular body with first and second legs that define an annular channel at the inside diameter face of the annular body. The annular channel is configured to define a pressure cavity within the annular groove between the first and second wellhead component. The outside diameter face of the annular body has a tapered profile in cross-section, and the first and second legs have enlarged ends configured for engaging the inside diameter wall of the annular groove.

Abstract: A system for supplying fracturing fluid to a fracturing tree coupled to a wellhead comprising: a zipper module having a lower block with a first opening configured to receive the fracturing fluid, the lower block being independently rotatable at a swivel assembly around a vertical axis relative to the lower block; an upper block with a second opening configured to dispel the fracturing fluid, the upper block being independently rotatable at a swivel connection around the vertical axis; an internal flow path between the upper block and the lower block; and a fluid conduit between the zipper module and the fracturing tree comprising at least one pipe, wherein the at least one pipe defines a first straight flow path between the zipper module and the fracturing tree.

Abstract: A method and apparatus according to which a hydraulic fracturing fluid is communicated to a wellhead, the apparatus including a fracturing tree connected to the wellhead and into which the hydraulic fracturing fluid is adapted to flow, a fluid conduit connected to the fracturing tree and through which the hydraulic fracturing fluid is adapted to flow before flowing into the fracturing tree, the fluid conduit defining a straight fluid flow path, and a zipper module connected to the fluid conduit and out of which the hydraulic fracturing fluid is adapted to flow before flowing through the fluid conduit. The hydraulic fracturing fluid flows along the straight fluid flow path of the fluid conduit upon flowing out of the zipper module, and continues to so flow along the straight fluid flow path until the hydraulic fracturing fluid flows into the fracturing tree.
