Abstract: A single conduit lift pump is disclosed that only requires a single fluid conduit for both the driving fluid and the pumping action of the pump in a well bore. Fluid pressure communicated to the pump by the single fluid conduit drives the pump to load a resilient member. The fluid pressure is cycled off to allowing the lift of fluid by action of the resilient member upon the single fluid conduit. The single fluid conduit makes this pump suitable for downhole operations for the oil and gas production industries in wells that have substantial water cut that inhibits the production of gas.

Abstract: A pressure actuated seal carrier assembly includes a seal carrier with a body with an inner and an outer projection that are integral with the body and opposite to one another. An inner groove with a first seal is formed in the inner projection, and an outer groove with a second seal is formed in the outer projection. As pressure enters the cavity, the projections are forced radically outward and inward, which maintains contact with the mating surfaces, thus excluding any no extrusion gaps between the seal carrier and the walls of the pressurized space. A spacer is located in the cavity to maintain space between the grooves and bear the axial load.

Abstract: Apparatuses and methods to communicate with a zone below a subsurface safety valve (104, 204, 404) independent of the position of a closure member (106) of the safety valve. The apparatuses and methods include deploying a subsurface safety valve (104, 204, 404) to a profile located within a string of production tubing. The subsurface safety valve (104, 204, 404) is in communication with a surface station through an injection conduit (150,152; 250,252; 450; 452) and includes a bypass pathway (144, 244, 444) to inject various fluids to a zone below.

Abstract: A Christmas tree is used between production tubing elevation and flow line elevation. The tree has a lower portion, an intermediate portion, and an upper portion. The intermediate portion is positioned between the production tubing elevation and the flow line elevation and has an axial dimension configured to substantially maintain the axial dimension between the elevations. The intermediate portion has first and second shut-off valves for closing fluid communication of the axial bore. A hanger is positioned in the axial bore of the intermediate portion between the first and second shut-off valves. The hanger defines a bore and a port. The port communicates a side of the hanger with the lower end of the hanger. The coil tubing attaches to the port at the lower end of the hanger, and the port at the side of the hanger communicates with the feed line of the intermediate portion.

Abstract: A method for removing particles Particles are removed from a high pressure flow stream entails by flowing the high pressure flow stream into an inlet of a high pressure trap and flowing the flow stream from the inlet into a tube in the high pressure trap. The tube is adapted to accelerate the flow stream. The flow stream leaves the tube and de-accelerates as the stream flows into a chamber. The method continues by contacting the The flow stream with contacts a plate wound helically around an outside surface of the tube. The plate creates a cyclonic effect with in the flow stream to remove particles from the flow stream. The particles are collected in a reservoir. The remaining Remaining particles are removed by flowing the flow stream towards a side outlet over the plate. The methods end by collecting the The remaining particles are collected in a the reservoir forming collected particles and dumping the . The collected particles are periodically dumped from the reservoir.
