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: 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.
