Title: Directional drilling system and apparatus
Inventor: CHANDLER ROY L
IPC: E21B47/022
Filed: 1999-06-04
Granted: 2007-10-09
Abstract: The apparatus, in one embodiment, has guide housing (113) with a shaft (101) extending through the guide housing (113) with a drill bit (105) coupled to its forward end (101F). The shaft (101) may be moved to a forward drilling position or to a rearward shifting position relative to the guide housing (113). A cam is located inside of the guide housing. A cam follower (131) is coupled to the shaft. In the shifting mode, the cam follower (131) is disengaged from the cam. A clutch (261) is provided for coupling the cam to the shaft when the shaft is in the shifting position such that the cam follower may be rotated with the shaft relative to the cam to allow the cam follower to engage the cam when the shaft is moved to the forward drilling position. In the forward drilling position of the shaft, the clutch releases the cam from the shaft and the cam follower engages the cam to allow straight drilling to occur or to cause the axis of said guide housing to shift relative to the axis of the shaft to cause the direction of drilling by the shaft and drill bit to change.

Abstract: A downhole system includes a deflector with a reaction surface that is engageable to a mill. The deflector is coupled to a motion mechanism that is activable to move the deflector generally along a longitudinal direction. During operation, the mill is engaged to a surrounding downhole structure, and the mill is rotated. As the mill cuts an opening in the downhole structure, the motion mechanism moves the deflector, which allows the mill to move with the deflector. A smooth motion is provided by the motion mechanism to enable a more accurate cutting of the downhole structure (e.g., casing or liner).

Title: Capacitance measuring systems
Inventor: DAVIS ANDREW CERI
IPC: G01R27/26
Filed: 2002-09-03
Granted: 2012-12-18
Abstract: It is known to measure the capacitance of a probe in a capactive fuel-gauging system by means of a reference capacitor. In the present invention the probe and reference capacitors are charged in opposite senses from respective dc voltage sources via switches operated in antiphase. Two further switches alternately discharge the capacitors to a 0 volts rail. The outputs of the probe and the reference capacitor are connected to a summing node, which is connected to an amplifier via a pair of switches operated in antiphase to rectify the output. The amplifier connects to a processor, which controls the relative outputs of the voltage sources and provides an output indicating the value of the probe.
