Abstract: A packing system for a pump includes a packing stack comprising a packing, wherein the packing is cylindrical and compressible such that the packing can fill a void volume in a reciprocating element bore of the pump; one or more springs; and a terminal component configured for sealing a terminus of the reciprocating element bore, wherein the one or more springs are positioned between the terminal component and the packing to provide a force on the packing that maintains compression of the packing within the void volume.

Abstract: A discharge valve assembly configured to control fluid flow out of a chamber of a pump fluid end of a pump, wherein the discharge valve assembly comprises a controllable holding system (CHS), wherein the CHS is controllable to hold the discharge valve assembly in an open configuration.

Abstract: A flow exchanger (FE) system comprising: a supplement pump receiving a supplement first fluid stream and outputting a pressurized supplement first fluid stream; a flow splitter comprising a flow restrictor, wherein the flow splitter receives the pressurized supplement first fluid stream and outputs a power stream and a treatment stream; a main flow manifold, wherein the treatment stream enters the main flow manifold subsequent to passing through the flow restrictor; and an FE cylinder filled downstream with a second fluid and having a fluid interface separator (FIS), wherein the power stream enters the FE cylinder upstream; wherein the power stream engages and pushes FIS downstream, thereby providing for a second fluid stream entering the main flow manifold; wherein a second fluid stream VFR=a power stream VFR; and wherein the main flow manifold provides for a manifold output fluid stream VFR=a pressurized supplement first fluid stream VFR.

Abstract: An actuatable wellbore isolation assembly including a housing defining an axial flowbore and including a mandrel portion, a first end portion, and a second end portion; a radially expandable isolating member positioned circumferentially about the housing; a sliding sleeve circumferentially positioned about the mandrel, the sliding sleeve being movable from a first position, in which the sliding sleeve retains the isolating member in a narrower non-expanded conformation, to a second position, in which the sliding sleeve does not retain the isolating member in the narrower non-expanded conformation; and an actuator assemblage configured to allow movement of the sliding sleeve from the first to the second position. In an exemplary embodiment, the actuator assemblage includes a biasing chamber having a biasing member disposed therein, wherein the biasing member is configured to apply a force to the sliding sleeve to move the sliding sleeve from the first to the second position.

Abstract: Embodiments of the hybrid tool string include coiled tubing and jointed tubing, as well as a means typically located at the connection of the coiled and jointed tubing for sealing the fluid flowpath through the bore of the hybrid tool string. Embodiments of the hybrid tool string may use a pressure-activated valve tool attached in series between the coiled tubing and the jointed tubing, which allows for sealing of the bore by application of pressure. Embodiments of the pressure-activated valve tool may use a flapper in conjunction with a sleeve to seal the bore. The novel hybrid tool string may be used to service a well.
