摘要： An apparatus for use in a wellbore is provided, which in one embodiment includes a drilling motor and a steering unit placed about a shaft between a lower section of a stator in the motor and a drill bit. The steering unit includes a substantially non-rotating member and a force application member on the non-rotating member configured to radially extend the force application member from the non-rotating member. In another embodiment, the steering unit may include, rotating member configured to rotate a drill bit, a steering member configured to orient the drill bit along a selected direction, a first steering device configured to orient the steering member in the wellbore, and a second steering device configured to maintain orientation of the steering member when drilling the wellbore.

摘要： An apparatus energizes a consumer of a pressurized fluid using a high pressure source and a low pressure source. The apparatus may include a fluid circuit in fluid communication with the consumer. The fluid circuit may have a first and a second reservoir. In one arrangement, the fluid circuit may have a flow control device in pressure communication with the first pressure source and the second pressure source, the flow control device being configured to cycle a pressure applied to the first and the second reservoirs using the first pressure source and the second pressure source. In some arrangements, the fluid circuit may include a flow device configured to flow fluid from a second branch to a first branch of the reservoir, and a flow control device in fluid communication with the flow device, the flow control device being configured to cycle a pressure applied to the flow device.
