Abstract
A flow transported obturating tool for actuating a valve in a wellbore includes a housing including a radially translatable engagement assembly, a core slidably disposed in the housing, an interrupt member disposed radially between the core and the housing, a bore sensor disposed in the housing and in engagement with the interrupt member, and a biasing member disposed in the housing and in engagement with the interrupt member.
Claims17
A flow transported obturating tool for actuating a valve in a wellbore, comprising:
- a housing comprising a radially translatable engagement assembly;
- a core slidably disposed in the housing;
- an interrupt member disposed radially between the core and the housing;
- a bore sensor disposed in the housing and in engagement with the interrupt member;
- and
- a biasing member disposed in the housing and in engagement with the interrupt member:
- wherein the interrupt member includes a first position permitting relative movement between the core and the housing, and a second position that restricts relative movement between the core and the housing:
- wherein a central axis of the interrupt member is offset from a central axis of the core when the interrupt member is disposed in the first position, and wherein the central axis of the interrupt member is aligned with the central axis of the core when the interrupt member is in the second position.
