Abstract: The present application relates to a system and method for real-time monitoring and failure prediction of electrical submersible pumps. The design includes generating a failure prediction value with a management system by calculating a percentage change of the respective first measurement values and the corresponding user-supplied stable operating values, the failure prediction value representing likelihood of failure of the electrical submersible pump.

Abstract: A method for downhole oil-water separation, according to one or more aspects of the present disclosure, comprises disposing a oil-water separation system in a wellbore, the system comprising a first separator connected in hydraulic series with a second separator; separating a well fluid in the first separator into a first injection stream and a first production stream; discharging the first injection stream to an inlet of the second separator; separating the first injection stream in the second separator into an output injection stream and a second production stream; and injecting the output injection stream from the wellbore into an injection formation.

Abstract: A downhole device having an oil/water separator having a well fluid inlet, an oil stream outlet conduit, and a water stream outlet conduit; a removable flow-restrictor located in at least one of the water stream outlet conduit or the oil stream outlet conduit.

Abstract: 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.

Abstract: Embodiments of the present invention generally relate to an electric submersible pumping system for dewatering gas wells. In one embodiment, 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.

Abstract: A downhole device having an oil/water separator having a well fluid inlet, an oil stream outlet conduit, and a water stream outlet conduit; a removable flow-restrictor located in at least one of the water stream outlet conduit or the oil stream outlet conduit.

Abstract: A technique is provided for processing well fluid downhole. The technique utilizes equipment for separating a well fluid downhole into a water component and an oil component. The separation of water and oil can be controlled by selecting an appropriately sized flow restrictor for use in limiting the flow of one or both of the water and the oil. Additionally, a sensor system is used to monitor a well characteristic that enables adjustment of the downhole fluid processing based on well characteristic data from the sensor system.
