20090056939 | FLOW CONTROL DEVICE AND METHOD FOR A DOWNHOLE OIL-WATER SEPARATOR - 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. | 03-05-2009 |
20090242197 | FLOW CONTROL SYSTEM AND METHOD FOR DOWNHOLE OIL-WATER PROCESSING - 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. | 10-01-2009 |
20100288493 | CABLE SUSPENDED PUMPING SYSTEM - 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. | 11-18-2010 |
20100288501 | ELECTRIC SUBMERSIBLE PUMPING SYSTEM FOR DEWATERING GAS WELLS - 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. | 11-18-2010 |
20110000675 | FLOW CONTROL DEVICE AND METHOD FOR A DOWNHOLE OIL-WATER SEPARATOR - 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. | 01-06-2011 |
20110146977 | TWO-STAGE DOWNHOLE OIL-WATER SEPARATION - 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. | 06-23-2011 |
20110297391 | COMPACT CABLE SUSPENDED PUMPING SYSTEM FOR DEWATERING GAS WELLS - 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 multi-section motor, an isolation device, and a pump. The method further includes supplying a power signal from the surface to the motor via the cable and sequentially operating each section of the motor to mimic a multi-phase motor, thereby driving the pump and lowering a liquid level in the tubular string to a level proximate the reservoir. | 12-08-2011 |
20110300008 | COMPACT CABLE SUSPENDED PUMPING SYSTEM FOR LUBRICATOR DEPLOYMENT - A method of installing or retrieving a pumping system into or from a live wellbore includes connecting a lubricator to a production tree of the live wellbore and raising or lowering one or more downhole components of the pumping system from or into the wellbore using the lubricator. | 12-08-2011 |
20120210926 | DC POWERED ROV AND UMBILICAL - A method of operating a remotely operated underwater vehicle (ROV) includes launching the ROV from a vessel into water; supplying a direct current (DC) power signal to the ROV from the vessel via an umbilical; and sending a first command signal to the ROV from the vessel via the umbilical while supplying the DC power signal. | 08-23-2012 |
20120211229 | CABLE DEPLOYED DOWNHOLE TUBULAR CLEANOUT SYSTEM - Embodiments of the present invention generally relate to cable deployed downhole tubular clean out system. In one embodiment, a method of cleaning a tubular string disposed in a wellbore includes connecting a cable to a BHA. The BHA includes a motor and a cleaner. The method further includes supplying a power signal to the BHA through the cable, thereby operating the motor to rotate the cleaner; deploying the BHA into the tubular string and the wellbore using the cable; and cleaning a deposit from an inner surface of the tubular string using the rotating cleaner. | 08-23-2012 |
20130192824 | COMPACT CABLE SUSPENDED PUMPING SYSTEM FOR DEWATERING GAS WELLS - A motor includes two or more sections.

20140158347 | METHODS AND APPARATUS FOR SENSING IN WELLBORES - Methods and apparatus for sensing wellbore conditions in artificial lift wells using low profile sensors that are installed on down hole production equipment that makes them easier to install and retrieve. In one embodiment, low profile sensors are installed on a rod string making their insertion and removal much easier than it would be if they were mounted on production tubing. The sensors can be attached directly to the rod string or can be attached to a cable that is attached to the rod string. The sensors can transmit their data electrically through the cable or through the rod string. Alternatively, the sensors can transmit their data acoustically through the rod string. | 06-12-2014 |
