| 20110088952 | Drill Motor Enhancement - Enhancements to a drill motor include a bearing pack assembly, a balancing piston, a recording transducer package (RTP), and a latch rod assembly for a drill motor to improve performance and reliability of a drill motor. The bearing pack assembly includes a bearing housing coupled to an end cap and a drive shaft extending into the end cap and the bearing housing. The bearing pack assembly also includes a thrust bearing disposed within the bearing housing, wherein the thrust bearing separates the drive shaft and the bearing housing, and a bearing sleeve disposed within the bearing housing, wherein a radial bearing is placed between the bearing sleeve and the drive shaft. The balancing piston includes a first and second hydrodynamic seal. The recording transducer package is self powered and gathers data from a plurality of sensors in the downhole tool. The latch rod assembly include a latch head is coupled to the rotor of a drill motor, wherein the latch head is larger than the opening in the bottom end of a top sub. | 04-21-2011 |
| 20110011594 | Mud Pulse Telemetry System - A mud pulser tool to be positioned into a downhole environment is disclosed. The mud pulser tool includes a control valve that is selectively opened to allow fluid to flow through the mud pulser tool or selectively closed to restrict the fluid flow, wherein the control valve is selectively opened or closed to produce a mud pulse signal transmitted through the fluid. The mud pulser tool also includes a sensor system to measure a pressure drop across the control valve. In one example, the mud pulser tool includes a control system to selectively open or close the control valve to adjust the pressure drop to produce a selected pressure drop across the control valve. | 01-20-2011 |
| 20100332137 | CASING DETECTION - A system and method for detecting casing is provided. In one example, a method for detecting drill casing in a downhole environment includes the steps of generating a plurality of plots of a magnetic field vector (MIN) at a series of depths; and monitoring the plots to detect proximity to the well casing. | 12-30-2010 |
| 20090115625 | MWD data transmission - An MWD data transmission system and method for determining and transmitting the environmental properties of the downhole borehole assembly (BHA) to surface data receivers via mud pulse telemetry, EM telemetry, or both mud pulse telemetry and EM telemetry based on one or more determined properties of the downhole environment. | 05-07-2009 |
