  • Retrieval of multi-component plunger in well plunger lift system
    Patent number: 10689956
    Abstract: A plunger lift method can include introducing a plunger sleeve and a plunger closure into a well, engaging the sleeve with the closure, securing the sleeve and closure to each other in a flow passage of the well, and then retrieving the sleeve and closure from the well. A plunger lift system can include a plunger sleeve configured for reciprocal displacement in a flow passage of the well, a plunger closure configured to block flow through a flow path of the sleeve and being displaceable in the flow passage separate from the sleeve. A plunger retrieval device may displace with the sleeve in the flow passage and secure the closure against displacement away from the sleeve. Another plunger retrieval device may be positioned in a lubricator, whereby the plunger retrieval device engages the closure and secures the closure against displacement away from the sleeve in the lubricator.
