Abstract: A fluid management system positioned in a wellbore for recovering a multiphase stream from the wellbore. The system comprising a downhole separator configured to produce a carrier fluid having a carrier fluid pressure and a separated fluid having a separated fluid pressure, an artificial lift device configured to increase the carrier fluid pressure to produce the turbine feed stream having a turbine feed pressure, a turbine configured to convert fluid energy in the turbine feed stream to harvested energy, the conversion fluid energy from the turbine feed stream to harvested energy produces a turbine discharge stream having a turbine discharge pressure less than the turbine feed pressure, and a pressure boosting device configured to convert the harvested energy to pressurized fluid energy, the conversion of harvested energy to pressurized fluid energy produces a pressurized fluid stream having a pressurized fluid pressure greater than the separated fluid pressure.

Abstract: A tubing hanger assembly for use in a wellhead assembly that includes tubing hanger member, a retainer that lands in the hanger member, and slip assembly landed in the retainer that supports a string of composite tubing and an electrical submersible pump assembly (ESP). The tubing and ESP are disposed in a wellbore formed beneath the wellhead assembly. The slip assembly is non-marking and includes grit on its inner surface rather than teeth.

Abstract: A system for displacing fluid inside of a tubular member includes at least one peristaltic pump. Each peristaltic pump includes an elongated core member with a longitudinal axis located within the tubular member. A flexible member surrounds, and is concentric to, the elongated core member. The flexible member has a plurality of circular bands disposed along a length of the flexible member, each circular band being moveable between a contracted condition with a minimal radius and an expanded condition with a maximal radius. An outer membrane covers the circular bands, forming a first fluid cavity between an outer surface of the outer membrane and an inner surface of the tubular member. The outer membrane is operable to generate peristaltic waves in the first fluid cavity by selectively moving each circular band between the contracted condition and the expanded condition.

Abstract: A method of homogenizing a production fluid from an oil well having one or more wellbores includes separating gas from the production fluid in a vertical or horizontal section of a well casing at a first location spaced from a heel portion of a wellbore, and injecting the separated gas into the production fluid at a second location spaced from the heel portion of the wellbore and provided downstream of the first location.

Abstract: A system for and method for homogenizing the liquid and the gas and including providing a tube arrangement, first breaking up and separating the slugged gas from the liquid at a first location, and then gathering it into holding location—i.e., an annulus section of the flow tube—where it is re-introduced in controlled amounts into the liquid downstream of the first location. Various alternative gas/liquid separation devices are incorporated into the system which devices may be located either in a vertical wellbore or a horizontal wellbore, depending upon the particular well characteristics.

Abstract: A system and method for improving the flow characteristics of gaseous slug-laden liquid hydrocarbon wells, particularly from horizontal, of similar boreholes. The invention provides a system and method which essentially homogenizes the liquid and the gas, utilizing a unique flow tube arrangement and a sequence of steps by first breaking up and separating the slugged gas from the liquid at a first location, and then gathering it into holding location—i.e., an annulus section—where it is re-introduced in controlled amounts into the liquid downstream of the first location. The gas is re-introduced into the liquid flow in such pre-determined and controlled quantities as to promote better pressure and flow characteristics of the hydrocarbon liquid product. Various alternative gas/liquid separation devices are incorporated into the system of the invention, which devices may be located either in a vertical wellbore or a horizontal wellbore, depending upon the particular well characteristics.
