摘要： Embodiments of the present invention generally relate to a cable suspended pumping system. In one embodiment, a method of producing fluid from a reservoir includes deploying a pumping system into a wellbore to a location proximate the reservoir using a cable. The pump assembly includes a motor, an isolation device, a pump, and a power conversion module (PCM). The method further includes setting the isolation device, thereby rotationally fixing the pumping system to a tubular string disposed in the wellbore and isolating an inlet of the pump from an outlet of the pump; supplying a DC power signal from the surface to the PCM via the cable; and supplying a second power signal to the motor, thereby operating the pump and pumping reservoir fluid from the reservoir to the surface.

摘要： A method of unloading liquid from a reservoir includes deploying a pumping system into a wellbore to a location proximate the reservoir using a cable. The pumping system includes a motor, an isolation device, and a pump. The method further includes setting the isolation device, thereby rotationally fixing the pumping system to a tubular string disposed in the wellbore and isolating an inlet of the pump from an outlet of the pump; supplying a power signal from the surface to the motor via the cable, thereby operating the pump and lowering a liquid level in the tubular string to a level proximate the reservoir; unsetting the isolation device; and removing the pump assembly from the wellbore using the cable.

摘要： The invention provides a separator for the removal of solids from a drilling liquid, the separator comprising a tube settler (4) through which the drilling liquid can flow and beneath which a particle collection container is arranged for collecting solids separated from the liquid in the tube settler, wherein the solids collection container is a transportable container that is separate or separable from the tube settler. The invention further provides a process for the removal of solids from a drilling liquid using a separator, in which process a drilling liquid comprising solids is set to flow through a tube settler in order to allow the solids to settle out, thereby obtaining a solids depleted drilling liquid and an accumulation of solids. The invention also provides for the use of a separator comprising a tube settler to remove solids from a drilling liquid.
