    摘要： A process for the recovery of hydrocarbon such as bitumen/EHO from a hydrocarbon bearing formation in which are situated an upper injection well and a lower production well, the method comprising the steps: preheating an area around and between the wells by circulating hot solvent through the completed interval of each of the wells until sufficient hydraulic communication between both wells is achieved; injecting one or more hydrocarbon solvents into the upper injection well at or above critical temperature of the solvent or solvent mixture, thereby causing a mixture of hydrocarbon and solvent to flow by gravity drainage to the lower production well; and producing the hydrocarbon to the surface through the lower production well. A non-condensable gas may be injected into the solvent chamber created by the hydrocarbon solvent.

    摘要： A method and apparatus controls a compressor, where the compressor inlet gas may contain water and/or non-aqueous liquid. The method includes the steps of measuring temperature at the compressor inlet and/or outlet side, measuring pressure at the compressor inlet and outlet side in order to determine a compressor pressure ratio, measuring fluid mixture density at the compressor inlet and/or outlet side, measuring individual volume fractions of gas, water and non-aqueous liquid at the compressor inlet and/or outlet side, measuring fluid velocity at the compressor inlet and/or outlet side, and determining individual flow rates of gas, water and non-aqueous liquid on the basis of the measured individual volume fractions of gas, water and non aqueous liquid and the fluid velocity at the compressor inlet and/or outlet side.

    摘要： A process for the recovery of hydrocarbons from a hydrocarbon bearing formation and in which are situated an upper injection well and a lower production well is presented. The region between the wells is preheated by circulating hot solvent through at least part of both of the wells until hydraulic communication between both wells is achieved. Solvent is injected into the upper injection well at or above its critical temperature and the solvent is pentane or a mixture of butane and pentane. A hot solvent chamber is created consisting of solvent vapour and liquid. Bitumen and solvent are mixed at the boundary of the solvent chamber so formed. The hydrocarbon and solvent are caused to be mixed to drain downwards by gravity and sideways by pressure gradient towards the lower production well. The mixture is produced to the surface through the lower production well.

    摘要： Separation device or unit for separating liquid from an inlet flow which mainly contains gas, has a container or a pipe section with an outlet for gas from the container or the pipe section, an outlet for liquid from the container or pipe section and an inlet for the inlet flow to the container or pipe section. The device has a flow manifold arranged to receive and direct the inlet flow towards a porous pipe body extending towards the gas outlet and arranged to receive all or most of the inlet flow. Part of the flow is flowing through the tubular body to the gas outlet, while the remaining flow is flowing through the tubular body's porous wall, and an annular space including the volume between the tubular body and the container wall or pipe section is open for gas flow towards the gas outlet.
