摘要： An actuation system and method, the system including a tubular having a passage, and an assembly disposed with the tubular. The assembly includes a degradable restriction, the restriction only partially blocking the passage prior to being degraded. The assembly is configured to receive and prevent further movement of a restrictor through the tubular prior to the restriction being degraded. The assembly is further configured to release the restrictor when the restriction is degraded.

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A running string and setting tool that creates relative movement deliver the plug and pull on its lower end while holding the top stationary against a backing plate. The container is pulled into itself as the radial dimension grows for the set. There can be a mandrel that remains in position and can lock to the backing plate or alternatively there can be no mandrel or a removable mandrel. The porous container can be removed in a variety of ways to let the solid material escape to be removed with fluid circulating in the wellbore. Alternatively the mandrel can be undermined to let the solid material escape for recovery.

摘要： A frac plug mandrel assembly has an inner core that permits flow that is surrounded by a thin wall tube that distributes compressive loading, such as that applied by the set sealing element to the core. The core is a cylindrically shaped insert for inside the tube and allows flow until a ball or plug is landed on a seat to close off the flow through the core. The core can have a star pattern with a series of radially extending segments from a solid hub or a cylindrical shape of a honeycomb or other porous structure that has the requisite strength to resist collapse from compressive loading of the set sealing element while still allowing sufficient flow area for fluid displacement.

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A swage is moved through a passage in the container to enlarge the passage and move the container to a borehole wall. The passage is then closed such as with a flapper valve or by moving in a mandrel into the expanded passage and lodging the mandrel in the expanded passage. Various release techniques are described.
