Abstract: A setting tool disposed on tubing runs a packer into casing. During a setting process, a plug is engaged on a seat of an intensifying piston disposed in the tool. Tubing pressure applied against the seated plug moves the intensifying piston, which produces intensified pressure on fluid in a first volume of the intensifying piston communicated to a second volume of a setting piston. In response, the setting piston moves on the tool toward the packer's packing assembly. At some point in the process, the seated plug can be released from the seat. Additionally in the process, the second volume can fill with actuation fluid drawn through a fill valve from an annular space between the setting tool and the casing. The intensifying piston can then be reset as the actuation fluid is communicated from the second volume to the first volume.

Abstract: A gas lift device includes a housing, a valve, and a nozzle. The housing defines a chamber and defines an inlet and an outlet in communication with the chamber. The valve in the chamber permits fluid communication from the inlet toward the outlet and prevents fluid communication in the reverse. The nozzle disposed in the chamber has a converging section, a throat, and a diverging section, which extend along a longitudinal axis of the chamber. A surface of the converging section converges inwardly from the chamber to the throat to funnel fluid communication from the inlet to the throat. A flow restriction of the throat restricts the fluid communication from the converging section to the diverging section. A surface of the diverging section diverges outwardly from the throat toward the outlet. Vanes extend inwardly in the diverging section and spiral about the longitudinal axis.

Abstract: An equivalent circulating density (ECD) reduction tool can include a positive displacement fluid motor, and a fluid pump configured to be driven by the fluid motor. The fluid pump can include a fluid inlet and a fluid outlet disposed on respective opposite sides of an external flow restriction.

Abstract: A flowback tool is used on a top drive for delivering fluid flow to a tubular, such as a drillpipe or casing. A mechanical stroke on the tool has a mandrel with a mud saver valve and has a barrel. The mandrel connects to a quill of the top drive and has a coupling that can be threaded with the tubular's box connection. The barrel disposed on the mandrel can be moved by a cam engagement as the mandrel is rotated. When prevented from rotating, the barrel can thereby move in a stroke direction along an axis. An annular seal on the barrel is configured to sealably engage with the tubular. A clutch disposed on the barrel can prevent rotation of the barrel when the clutch is engaged with a portion (bail) of the top drive. However, a toque threshold of the clutch allows for slippage during operations.
