Abstract: A composite fracturing tree includes an operating valve and a master valve in fluid communication with the operating valve. The master valve includes an inlet portion in fluid communication with the operating valve, an outlet portion, and a gate portion. The gate portion is disposed between the inlet portion and the outlet portion. The gate portion is moveable between a flow position and an occluding position. In the flow position, the gate portion permits flow between the inlet portion and the outlet portion. In the occluding position, the gate portion prevents flow from the inlet portion to the outlet portion. The gate portion is actuated from the flow position to the occluding position with a closing force and from the occluding position to the flow position with an opening force. The master valve allows for the closing force to reduced compared to conventional fracturing valves.

Abstract: A replaceable subsea filter uses a hot-stab style connection. The filter has a flow path located along a central axis. At a distal end of the of the filter, the flow path locates inside a subsea receptable, typically associated with a reservoir or sea chest for a hydraulic actuator. At a proximal end, the flow path opens into an annulus around the stab-connecter, the annulus being separated from the surrounding waters by annular filters.

Abstract: Изобретение относится к добывающей отрасли и может быть использовано при добыче углеводородов, воды, кислотно-щелочных и солевых растворов и иных жидкостей газлифтным способом. Технический результат заключается в обеспечении стабильно высокой точности регулирования расхода агента без уменьшения межсервисных периодов времени эксплуатации и возможности оптимизации соотношения расход агента/добыча флюида при многоскважинной эксплуатации. Технический результат достигается тем, что автоматизированная система повышения эффективности работы скважин газлифтного способа эксплуатации содержит для каждой скважины узел регулирования, установленный на входе в затрубное пространство скважины, и узел контроля параметров добычи флюида, установленный на выходе из насосно-компрессорной трубы скважины, а также по меньшей мере один блок управления, функционально связанный со всеми узлами регулирования и контроля параметров. Заявляемая автоматизированная система повышения эффективности работы скважин газлифтного способа эксплуатации обеспечивает возможность различных режимов подачи газлифтного агента в каждую скважину и позволяет увеличить общий объем добычи флюида при минимальном расходе агента.

Abstract: A well tubing system (100) includes a well tubing (114) extending from a wellhead (104) and disposed in a wellbore (102), and multiple capillary tubes (120) coupled to the wellhead and extending from the wellhead into an annulus formed between an outer surface of the well tubing and a wall of the wellbore. The multiple capillary tubes provide a sealing fluid to the annulus, and extend to a respective multiple depths in the wellbore, where the multiple depths are different from each other. The capillary tubes guide the sealing fluid from the wellhead into the annulus, and provide the sealing fluid to the annulus.

Abstract: A subsea tree assembly with a flow monitoring and measuring apparatus includes a production wing valve block coupled to a production wing branch, the production wing valve block including a wing block connector, and a fluid processing module including a frame, a module connector including an inlet and an outlet, and a fluid flow loop coupled between the inlet and the outlet, wherein the module connector is fluidicly coupled to the wing block connector. A production fluid flow goes from the production wing valve block and returns to the same block via the wing block connector, the module connector, and the fluid flow loop. A flow monitoring and measuring apparatus for a subsea tree assembly includes a module frame, a module connector connectable to a production wing valve block, the module connector including an inlet and an outlet, and a fluid flow conduit forming a loop from the outlet of the module connector back to the inlet of the module connector.

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: A sealing assembly for use in a wellbore tool includes thermoplastic materials arranged in a lattice structure to provide a bulk elasticity on the order of elastomeric materials. The lattice structure permits an energizing element of the sealing assembly to deform sufficiently in the elastic range of the thermoplastic materials to provide repeatable sealing capabilities. The lattice structure may be constructed by additive manufacturing processes to include voids therein, which allow the thermoplastic members of the lattice to flex and bend. The energizing element may thereby exhibit a greater elasticity in bulk than the elasticity of the thermoplastic materials themselves. The lattice structure may be enclosed in an outer cover constructed of a polymeric, elastomeric or other material to facilitate the interaction between the seal assembly and the corresponding sealing surfaces of a downhole wellbore tool.
