Abstract: Systems and methods include a plug activated mechanical isolation device that controls fluid flow inside a tubular in a wellbore. The device includes a sleeve for coupling to the tubular, and the sleeve includes an internal bore and port for fluid flow therethrough. A channel element is positioned in the internal bore and includes an internal channel and an orifice for fluid flow between the internal channel and internal bore. The channel element is attached to the sleeve via a breakable attachment portion, and the orifice is aligned with at least one port of the sleeve. The channel element is slidable within the sleeve, upon breakage of the breakable attachment portion with a force, to move the orifice out of alignment with the port of the sleeve so that a portion of the channel element covers the port of the sleeve to block fluid flow through the port.

Abstract: Systems and methods include a mechanical isolation device that comprises a sleeve, which includes a port for fluid flow between an internal bore of the sleeve and an inside of a tubular. A receiver positioned in the internal bore includes a first orifice at a first axial location on the receiver, and a second orifice at a second axial location on the receiver. The second orifice is either aligned or un-aligned with the port of the sleeve. The receiver is slidable within the sleeve to: (i) move the first orifice into alignment with the port and either move the second orifice out of alignment with the port or keep the second orifice out of alignment with the port; and (ii) move the first orifice out of alignment with the port so that a portion of the receiver covers the port to block fluid flow between the internal bore of the sleeve and the port.

Abstract: An apparatus, system, and method of use that enables control of fluid flow in a wellbore drill string with a pilot. The apparatus comprises a pusher rod with a bore for fluid flow contacting a rotatable ball with an internal bore comprising at least one pilot, wherein the seat between the pusher rod and the interior of the tubular prevents fluid flow. Pressure changes on the pusher rod rotate the bore of the ball in and out of contact with the bore of the pusher rod, to enable or prevent fluid flow, respectively. A method of use opens the ball by exerting pressure and/or force on the pusher rod to enable fluid through the ball by aligning the internal bores. Fluid flow is stopped by pressure exerted on the bottom of the ball causing the ball to rotate whereby the internal bore of the pusher rod is connected to the exterior surface of the ball. An accumulator can control the operations of the valve by selectively exerting pressure and/or fluid flow on the pusher rod.

Abstract: A system and method for controlling fluid flow inside a tubular in a wellbore includes a tubular comprising an internal bore and a latch profile on an inner surface of the tubular. A receiver is positioned within the internal bore of the tubular at the latch profile so that the tubular and the receiver form a unit for insertion into the wellbore. An interior of the receiver defines a fluid flow channel, and the fluid flow channel includes an internal taper. A float valve is provided for dropping into the wellbore and the receiver. The float valve includes an external taper at an external surface of the float valve, and the external taper abuts against the internal taper of the receiver so that the float valve in the receiver blocks the fluid flow channel.

Abstract: An apparatus, system, and method of use that enables control of fluid flow in a wellbore drill string with a pilot. The apparatus comprises a pusher rod with a bore for fluid flow contacting a rotatable ball with an internal bore comprising at least one pilot, wherein the seat between the pusher rod and the interior of the tubular prevents fluid flow. Pressure changes on the pusher rod rotate the bore of the ball in and out of contact with the bore of the pusher rod, to enable or prevent fluid flow, respectively. A method of use opens the ball by exerting pressure and/or force on the pusher rod to enable fluid through the ball by aligning the internal bores. Fluid flow is stopped by pressure exerted on the bottom of the ball causing the ball to rotate whereby the internal bore of the pusher rod is connected to the exterior surface of the ball. An accumulator can control the operations of the valve by selectively exerting pressure and/or fluid flow on the pusher rod.
