|20100244595||HEAT TRANSFER THROUGH ELECTRICAL SUBMERSIBLE PUMP MOTOR - The motor of an electrical submersible pump generates a significant amount of heat that can be removed by transferring it to the well production fluid. Grooves in the stator and motor housing facilitate more rapid heat transfer from the rotor and stator, through the motor lubricant, to the motor housing. Increased heat transfer to the motor housing facilitates increased heat transfer to the production fluid on the outside of the motor housing.||09-30-2010|
|20100150739||HEAT TRANSFER THROUGH THE ELECTRICAL SUBMERSIBLE PUMP - The motor of an electrical submersible pump generates a significant amount of heat that can be removed by transferring it to the well production fluid. The motor housing may have turbulators that increase the turbulence of the production fluid to increase the rate of heat transfer. The turbulators are designed for manufacturability and maintenance.||06-17-2010|
|20100089657||SPACER RING FOR ELASTOMERIC SEAL - A roller cone bit is provided that includes a companion ring positioned adjacent to the seal, wherein the companion ring is formed of a porous material that is compatible with the fluid lubricating the interface between the roller cone and the bearing pin.||04-15-2010|
|20100071959||THREADED CONE RETENTION SYSTEM FOR ROLLER CONE BITS - An apparatus and method for retaining a roller cone on a bearing pin of a drillbit body.||03-25-2010|
|20100065280||GAS RESTRICTOR FOR HORIZONTALLY ORIENTED PUMP - An inlet apparatus for a submersible well pump.||03-18-2010|
|20090152007||OPTIMIZING DRILLING PERFORMANCE USING A SELECTED DRILLING FLUID - To improve drilling performance, a drilling fluid is selected based on one or more criteria and to have at least one target characteristic. Drilling equipment is used to drill a wellbore, and the selected drilling fluid is provided into the wellbore during drilling with the drilling equipment. The at least one target characteristic of the drilling fluid includes an ability of the drilling fluid to penetrate into formation cuttings during drilling to weaken the formation cuttings.||06-18-2009|
