摘要： 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 running tool such that rotation of the running tool causes the plurality of extendable latches to an extended position.

摘要： Provided is a downhole fracturing tool assembly, a well system, and a method for fracturing a well system. The downhole fracturing tool assembly, in one aspect, includes a fracturing port cover coupleable to an interior of a wellbore casing having one or more fracturing ports therein. The downhole fracturing tool assembly, according to this aspect, further includes a fracturing port cover actuator coupled to the fracturing port cover, the fracturing port cover actuator operable to move the fracturing port cover between a first position sealing the one or more fracturing ports from an interior of the wellbore casing and a second position exposing the one or more fracturing ports to the interior of the wellbore casing, and fracturing port cover electronics coupled to the fracturing port cover actuator proximate the fracturing port cover, the fracturing port cover electronics operable to activate the fracturing port cover actuator.

摘要： The invention relates to the valve block (100) developed for use in the geothermal industry, which allows geothermal fluid to be brought to the surface from the bottom of the well. Developed for use in geothermal hot water wells that have lost their artesian flow capability and whose well bottom pressures have fallen, the valve block (100) of the invention restores the production and well Artesian flow capability and increases the flow and production amount in wells where the surface flow amount has decreased.

摘要： A downhole tool for transmitting rotation to a casing string includes a tool body (402) having a bore (536) extending from a first end to a second end. The downhole tool also includes a cam (530) positioned within the tool body (402), the cam (530) being axially translatable along an axis (500) of the bore (536). The downhole tool further includes a recess (522), formed in an outer diameter of the cam (530). The downhole tool includes a locking mechanism (524), positioned at least partially within the tool body (402). The locking mechanism (524) includes a tool key (518). The locking mechanism (524) also includes a biasing member (526), the biasing member (526) driving the tool key (518) toward the retracted position.

摘要： A valve useful in an inflow control device for downhole use in an oil and gas well completion equipment is disclosed. The valve may have a flexible canopy that prevents fluid flow between the base pipe and the formation when flow travels in a first direction and permits fluid flow between the base pipe and the formation when flow travels in a second direction.

摘要： An apparatus includes a cylindrical housing having a hinge, a flapper attached to the hinge, and a slidable element is within the cylindrical housing, wherein the flapper can rotate from a first flapper position to a second flapper position. The slidable element is slidable from a first slidable position to a second slidable position and engages with the flapper at the first slidable position to prevent the flapper from moving to the second flapper position. The flapper is movable to the second flapper position when the slidable element is disengaged from the flapper. The apparatus also includes a latching mechanism attached to the slidable element movable from a first latching mechanism position to a second latching mechanism position. The slidable element is at the first slidable position when the latching mechanism is at the first latching mechanism position and at the second slidable position when the latching mechanism is at the second latching mechanism position.

摘要： Embodiments of an equalizing device for use with a safety valve and a safety valve are provided herein. In one embodiment, the equalizing device includes at least a tubular having a central bore extending axially there through, the tubular having a ball seat. The equalizing device may further include a ball positioned proximate the ball seat, the ball configured to move from a first position engaged with the ball seat to a second position disengaged from the ball seat to equalize pressure across the safety valve, and an arced ring positioned radially outside the ball, the arced ring configured to keep the ball engaged with the ball seat when in the first position and maintain the ball radially outside the ball seat when in the second position.
