Abstract: 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.

Abstract: A lens accessory for a video game sensor device and a method of adjusting a sensing distance of a video game sensor device. A lens accessory for a video game sensor device includes a first lens configured to cover an infrared light emitter of the video game sensor device, a second lens configured to cover an infrared light receiver of the video game sensor device, and a body portion coupling the first lens and the second lens together, the body portion being removably attachable to the video game sensor device, and the first lens and the second lens having a magnification for adjusting a sensing distance of the video game sensor device.

Abstract: A system and method for transmitting mud pulse signals in a downhole environment is disclosed. In one embodiment, a mud pulser system includes a valve (32), a wire (26) comprising shape memory alloy (SMA), and operable to have a first shape at a first temperature and a second shape at a second temperature; a thermal energy source (18) to heat the wire (26) from the first temperature to the second temperature; and a valve poppet (32) coupled to the wire, wherein the valve poppet is extended to close the valve when the wire is in the first shape and wherein the valve poppet is retracted to open the valve when the wire is in the second shape.

Abstract: 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.
