Abstract: An integrated wellhead assembly is provided to enable free flow production and artificial lift production from a well without requiring removal and/or reconfiguration of the wellhead assembly. The wellhead assembly includes an upper portion and a lower portion forming an integrated assembly. The upper portion includes a flow tee and at least one set of rams. The lower portion includes a shoulder to receive a hanger. The upper portion may seal the bore of the wellhead assembly and provide full bore access to the bore of the wellhead assembly.

Abstract: A downhole moineau pump assembly includes a stator with a rotor extending through the stator. The rotor and stator sealingly engage each other at spaced intervals to form a series of annular spaces. A primary inlet is provided for fluids to enter a first of the series of annular spaces. A surface mounted top drive unit rotates the rotor. As the rotor rotates, fluids are drawn through the primary inlet and up the series of annular spaces between the rotor and the stator. A portion of the rotor is hollow with a central flow passage extending from a secondary inlet spaced from the primary inlet to the primary inlet. A portion of the fluids being pumped to surface are diverted into the secondary inlet and pumped under pressure down the central flow passage of the rotor to the primary inlet, thereby washing accumulated solids form the primary inlet.
