Abstract: Disclosed is a tubing system for transporting a gas-liquid flow from a well to a production platform or processing facility. It includes a dual pathway section between the well and the production point having a first tubing portion and a second tubing portion. The second tubing portion includes a plurality of parallel channels so as to divide the multi-phase flow into a plurality of flows through individual channels. This is done to reduce flow slippage of the lower viscosity portion of the flow, which may lead to inefficiencies in flow characteristics, and often, undesirable cyclical variations in pressure and fluid volume. This is especially useful in inclined portions of the petroleum flow pipe system and along hilly terrain. The first round tubing portion is used for transporting the gas-liquid flow as well as for maintenance purposes, such as for pigging, fishing or coiled tubing operations.

Abstract: A method and apparatus to reduce the axial thrust in rotary machines such as compressors, centrifugal pumps, turbines, etc. includes providing additional peripheral restrictive means (7) attached at the peripheral portion of the disk forming the subdividing means (4) on the side facing the rotating rotor (2). An additional ring element at the periphery of the subdividing means forms additional radial (11) and axial restrictive means (15). Such peripheral restrictive means (7, 11 and 15) function as sealing dams, which combined with the outward flow induced by the rotating impeller, form self-pressurizing hydrodynamic bearings in the axial and radial planes, improving rotordynamic stability. Additionally, a stationary ring element in the center of the cavity forms a seal with the rotor, reducing leakage to suction.

Abstract: During production of hydrocarbons, an oil-gas flow from a well bottom to a well-head is subdivided into a plurality of individual oil-gas flows which flow in a plurality of individual passages (2, 3) located side-by-side with one another.
