Title:
WELLBORE VALVE, WELLBORE SYSTEM, AND METHOD OF PRODUCING RESERVOIR FLUIDS
Document Type and Number:
WIPO Patent Application WO/2011/106579
Kind Code:
A3
Abstract:
A wellbore valve (200) includes a valve body (201) having an inlet port (210), an outlet port (216), and an axial bore. A screen (202) is mounted on the valve body and positioned in a flow path (206) between an exterior of the valve body and the inlet port for filtering a fluid flowing into the inlet port along the flow path. A valve member (220) is disposed in the axial bore. The valve member is movable relative to the valve body between a first valve position where the valve member opens up the inlet port to the axial bore and closes off the outlet port from the axial bore and a second valve position where the valve member closes off the inlet port from the axial bore and opens up the outlet port to the axial bore.
