    Abstract: An illustrative modular manifold disclosed herein includes, among other things, a low-pressure manifold comprising a frac fluid outlet valve, wherein a fracturing fluid is adapted to be supplied from the low-pressure manifold via the frac fluid outlet valve to a suction side of a frac pump, and a high-pressure manifold comprising at least one frac fluid inlet valve, wherein the high-pressure manifold is adapted to receive, via the frac fluid inlet valve, a fracturing fluid discharged from the frac pump. In this example, the modular manifold also includes a support structure for mechanically supporting the low- and high-pressure manifolds and a plurality of height-adjustable support legs operatively coupled to the support structure.

    Abstract: A system for transferring fluid from a pump to a manifold, the manifold having a plurality of fluid inlets. A first pump truck includes a first pump having a first fluid outlet. A first flexible pipe couples the first fluid outlet to a first fluid inlet. The first flexible pipe is self-supporting and forms an arch extending over the first pump truck. The first pump truck may include a second pump having a second fluid outlet and a second flexible pipe may couple the second fluid outlet to a second fluid inlet. A second pump truck may include third and fourth pumps having third and fourth fluid outlets, respectively, that may be coupled to third and fourth fluid inlets by third and fourth self-supporting flexible pipes.

    Abstract: A wireline pressure control string for use in performing wireline operations on a hydrocarbon well is disclosed. The wireline pressure control string includes a pumpdown assembly having a pumpdown sub and at least one pumpdown valve. The pumpdown sub includes a body and a through bore which extends axially through the body and is fluidly connectable to the well bore. The pumpdown valve includes an inlet which is fluidly connectable to a pumpdown fluid source and an outlet which is fluidly connected to the through bore. The wireline pressure control string may also include a connector positioned below the pumpdown assembly for releasably securing the wireline pressure control string to the wellhead assembly. In certain embodiments, the pumpdown valve may be connected to the pumpdown fluid source with a flexible flowline.

    Abstract: A pipe assembly includes a flexible pipe segment and at least one end fitting. The at least one end fitting includes an end casing coupled to the flexible pipe segment and a seal housing removably coupled to the end casing. The end casing defines a seal housing-receiving bore extending longitudinally through the end casing, and the seal housing is positioned within the seal housing-receiving bore. The seal housing defines at least one seal bore extending from an axially distal surface of the seal housing, and one or more sealing elements are seated in a respective one of the at least one seal bore. The end casing is couplable to a counterpart fitting, and the seal housing and/or the one or more sealing elements are configured to define a sealing interface with the counterpart fitting.

    Abstract: An illustrative modular manifold system includes, among other things, two or more modular pump manifolds, a low-pressure header, and a main high-pressure manifold. Modular pump manifolds may include a low-pressure manifold for supplying fracturing fluid or water to pumps, a high-pressure manifold for supplying fracturing fluid or water to one or more wells and a bleed-off/prime-up manifold. Each modular pump manifold of the modular manifold system is configured to be fluidly isolatable from the other modular pump manifolds. Each isolated modular pump manifold is configured to be flushed with water, bled off and primed up independently of the other modular pump manifolds. After the bleed off, maintenance procedures may be performed on pumps associated with the isolated modular pump manifold. The modular pump manifolds that are not isolated may continue in active fracing stage operations while a modular pump manifold is isolated.
