  • Patent number: 10900308
    Abstract: A system for activating a downhole tool may include a mandrel, a first piston disposed about the mandrel and defining a piston chamber therebetween, a flow restrictor positioned in the piston chamber and separating the piston chamber into an upper chamber located uphole of the flow restrictor and a lower chamber located downhole of the flow restrictor, and a second piston disposed in the upper chamber. The flow restrictor may define at least one orifice extending axially therethrough and, a damping fluid may reside in the piston chamber downhole from the second piston.
    Type: Grant

  • Patent number: 10822888
    Abstract: A method of protecting a nipple profile of a downhole tool that forms a portion of a tubing string and that is exposed to through-tubing completion operations includes securing a single-trip protective sleeve to the tool so that the sleeve covers the nipple profile of the tool during the completion operations and dissolving the single-trip protective sleeve so that it breaks away from the nipple profile to expose the nipple profile for use.

  • Patent number: 10590738
    Abstract: A flow control assembly includes a housing defining flow port that place an interior of the housing in fluid communication with an exterior of the housing, and a sliding sleeve defining sleeve ports and movably positioned within the interior between a first position, where fluid communication between the interior and the exterior via the flow ports is prevented, and a second positon, where fluid communication between the interior and the exterior is facilitated through the sleeve ports and the flow ports. A piston and a slip device are movably arranged within a piston chamber defined between the housing and the sliding sleeve. The piston has a first end exposed to an interior pressure and a second end exposed to an exterior pressure via chamber ports defined in the housing. A biasing device is also positioned within the piston chamber.

  • Patent number: 10161214
    Abstract: A system and method for selective isolation of multiple wellbore intervals that can include an isolation mandrel interconnected in a tubing string, where the isolation mandrel includes an entry bore, a transition chamber, and an exit bore, the transition chamber being positioned between the entry and exit bores, and the transition chamber being radially enlarged relative to the entry and exit bores. An isolation device, with a predetermined length, is displaced through the tubing string to the isolation mandrel, where the length of the isolation device relative to a length of the isolation mandrel can determine if the isolation device passes through the isolation mandrel or lands in the isolation mandrel.
