Abstract:
1. Apparatus for selectively controlling fluid flow downhole in conjunction with a progressive cavity pump (PCP), the apparatus comprising: a body member having a throughbore formed therein; at least one bypass port formed in the body member; a rotatable member arranged for insertion and rotation within the throughbore of the body member thereby creating first and second annular portions, wherein the rotatable member is located in use vertically above the PCP and is coupled to a rotor thereof such that rotation of the rotatable member rotates the rotor of the PCP; a moveable member; wherein the moveable member is moveable between a first configuration which defines a first fluid flow path between the first and second annular portions and a second configuration which defines a second fluid flow path between the first annular portion and the at least one bypass port; and wherein the moveable member translates from the second configuration to the first configuration when the PCP is activated and remains in the first configuration whilst the PCP remains in operation.
