20100047089 | HIGH TEMPERATURE MONITORING SYSTEM FOR ESP - An electric submersible pump device, comprising an electric motor having stators and coils; a pump coupled with the electric motor; a thermocouple or RTD for measuring temperature of the motor windings. | 02-25-2010 |
20100164303 | Submersible motor with ferrofluid gap - A technique enables reduction in electrical power losses during operation of a submersible motor. The technique utilizes a submersible motor comprising a housing that encloses a stator and a rotor. A ferrofluid is located in the housing in a sufficient quantity to fill the gap between rotor and stator. The ferrofluid has substantially improved properties that facilitate a reduction in electrical power supplied and thus a greater efficiency in operation of the motor. | 07-01-2010 |
20100200291 | COMPLETION SYSTEM HAVING A SAND CONTROL ASSEMBLY, AN INDUCTIVE COUPLER, AND A SENSOR PROXIMATE TO THE SAND CONTROL ASSEMBLY - A completion system for use in a well includes a first completion section and a second section. The first completion section has a sand control assembly to prevent passage of particulates, a first inductive coupler portion, and a sensor positioned proximate to the sand control assembly that is electrically coupled to the first inductive coupler portion. The second section is deployable after installation of the first completion section. It includes a second inductive coupler portion to communicate with the first inductive coupler portion, to enable communication between the first completion section's sensor and another component coupled to the second section. | 08-12-2010 |
20100236774 | COMPLETION SYSTEM HAVING A SAND CONTROL ASSEMBLY, AN INDUCTIVE COUPLER, AND A SENSOR PROXIMATE TO THE SAND CONTROL ASSEMBLY - A completion system for use in a well includes a first completion section and a second section. The first completion section has a sand control assembly to prevent passage of particulates, a first inductive coupler portion, and a sensor positioned proximate to the sand control assembly that is electrically coupled to the first inductive coupler portion. The second section is deployable after installation of the first completion section. It includes a second inductive coupler portion to communicate with the first inductive coupler portion, to enable communication between the first completion section's sensor and another component coupled to the second section. | 09-23-2010 |
20110260715 | VALVE POSITION SENSOR - A valve position sensor of a sliding sleeve of a flow control valve comprising a sleeve displacement converting means for converting a sleeve displacement into a radial displacement, and a measuring means for detecting the radial displacement and correlating the radial displacement to the position of the sliding sleeve within the flow control valve. | 10-27-2011 |
20140102796 | Method And Apparatus For Protecting Downhole Components With Inert Atmosphere - Methods and systems are provided that enable the removal or reduction of moisture and any other volatile substances within downhole tools. A purging gas can be allowed to flow into the downhole tool, where it begins to interact with and dry the moisture present as well as dilute the gaseous environment therein. Then purging gas then can exit the tool, thereby removing the moisture and any other potentially polluting or corrosive gases in the tool. A vacuum pump and desiccant jar assembly also can be used to further remove moisture from the tool. | 04-17-2014 |
