摘要： A ball dropper assembly includes a main body, a sealing piston, and a magazine assembly. The main body includes a main bore, angle bore, and transverse bore formed therethrough. The transverse bore is fluidly coupled to the main bore through the angle bore. The sealing piston is positioned within the transverse bore. Seal rings are positioned between the main body and the sealing piston on either side of the angle bore. The magazine assembly includes a magazine body and a carrier piston. The magazine body is mechanically coupled to the main body. The carrier piston has a carrier hole formed therein and is mechanically coupled to the sealing piston.

摘要： A fluid transfer system for use with a valve tree at a well, the valve tree having a wellhead axis, may comprise a header having a header flow axis and a coupler connected to the valve tree and the header and providing fluid communication between the valve tree and the header, the coupler having a coupler flow axis. The sum of the direction changes for a fluid flowing from the header into the valve tree may be less than 225°. The coupler may include a coupler inlet, which may be at substantially the same elevation as the header flow axis. The coupler may be connected to the header such that the coupler flow axis intersects the header flow axis or such that the coupler axis passes between the header axis and the surface of the earth. An angle between the coupler flow axis and the wellhead axis may be acute.

摘要： A fluid transfer system includes a valve tree, the valve tree having a master valve having a flow axis and a header. The fluid transfer system further includes a coupler disposed between, connected to, and in fluid communication with, the valve tree and the header. The coupler has a fixed length and includes a coupler multi-path flow connector in fluid communication with the valve tree. The coupler also includes a flow control valve having a flow axis, the flow control valve directly coupled to the coupler multi-path flow connector and in fluid communication with the header.
