Flapper on Frac Plug That Allows Pumping Down a New Plug |
| abstract |
A zonal isolation device comprising a sealing element comprising a deformable material and an inner bore; a support ring movably disposed within the inner bore of the sealing element; a rotatable sealing component coupled to the support ring and configured to engage a sealing surface of support ring, wherein the rotatable component blocks fluid flow through the zonal isolation device in a fully closed position, allows unrestricted fluid flow through the zonal isolation device in a fully open position, and allows restricted fluid flow through the zonal isolation device when held by a propping component in an intermediate or partially open position; a wedge engaged with a downhole end of the sealing element; an anchoring assembly engaged with the wedge; and an end element adjacent the anchoring assembly. |
