(54) | A Downhole Plug |
(57) A downhole plug for plugging and method of controlling fluids within a borehole in
an oil and/or gas well. The downhole plug has a body having a throughbore for the
passage of fluids. The plug also has a mechanical anchoring device that can radially
expand an anchoring member on an outer surface of the body to lock the body in a fixed
axial position within the borehole and an annular sealing device that can radially
expand a sealing member on the outer surface of the body to seal an annulus formed
between the outer surface of the body and an inner surface of the borehole. The plug
also has a throughbore plugging device that can change configuration between a first
open configuration in which the throughbore of the body permits the passage of fluid,
and a second closed configuration in which the throughbore resists the passage of
fluid.
