Abstract: Embodiments of the disclosure pertain to a system for production of a hydrocarbonaceous fluid, the system having a tubing string deployed within a wellbore; a first pump system having a pump assembly operably engaged with a motor; and a control system operably engaged with the first pump system. The pump assembly includes a housing with a stator and rotor disposed therein. The first pump system is operable to aid in production of the hydrocarbonaceous fluid from the wellbore to a production facility.

Abstract: A pump assembly comprising a stator and a rotor having vanes of opposite handed thread arrangements is described. A radial gap is located between the stator vanes and the rotor vanes such that rotation of the rotor causes the stator and rotor to co-operate to provide a system for moving fluid longitudinally between them. The operation of the pump results in a fluid seal being is formed across the radial gap. The described apparatus can also be operated as a motor assembly when a fluid is directed to move longitudinally between the stator and rotor. The presence of the fluid seal results in no deterioration of the pump or motor efficiency, even when the radial gap is significantly greater than normal working clearance values. Furthermore, the presence of the radial gap makes the pump/motor assembly ideal for deployment with high viscosity and/or multiphase fluids.

Abstract: A method of pumping a hydrocarbon fluid from a wellbore (4) and a hydrocarbon completion (1) implementing the methodology is described. The method comprises deploying a tubing string (7) and a first pump system (15), in fluid communication with the tubing string, within a wellbore. The first pump system is employed to generate a production fluid (17) by heating the hydrocarbon fluid as it is pumped into the tubing string so as to form a counter current heat exchanger between the production fluid within the tubing string and the hydrocarbon fluid located within the wellbore. The counter current heat exchanger provides a means for preheating the hydrocarbon fluid before it reaches the first pump system. As a result the viscosity of the hydrocarbon fluid is reduced thus making it easier to pump to the surface. The method finds particular application within horizontal, high angle or vertical wells in heavy or extra heavy oil fields.

Abstract: There is described a computer system for determining the relevance of stored content to particular users and for facilitating the provision of relevant content to individual users. The computer system comprises a content engine comprising user profile information, representative of interests and/or attributes of individual users, and a processor for determining a correlation between content and said user profile information to determine content most relevant to a particular user.
