Patent number: 9447677Abstract: 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.Type: GrantFiled: November 26, 2013Date of Patent: September 20, 2016Assignee: ESP COMPLETION TECHNOLOGIES L.L.C.Inventors: Lance I.

Patent number: 8006757Abstract: 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.Type: GrantFiled: February 25, 2009Date of Patent: August 30, 2011Assignee: Schlumberger Technology CorporationInventors: Matthew R.
