Abstract: A stepped reflector on the outside of a bottomhole assembly produces two reflections in response to excitation of a transducer. The velocity of the fluid in the borehole is estimated using the two reflections. Alternatively, a change in the gas content of the borehole fluid is estimated from changes in the electrical impedance of a transducer in contact with the borehole fluid.

Abstract: Devices and methods are described for establishing an effective annular seal about between an active pressure differential device (170) and a surrounding wellbore sidewall (90). The invention provides a means of selectively activating such a seal during drilling operations or other operations wherein drilling mud is flowed through the drill string and returns through the annulus. The annular seal assembly may include an inflatable packer element and a hydraulic inflation system. The hydraulic inflation system uses the fluid pressure provided by drilling mud that is returning to the surface via the annulus to inflate the packer element and set the seal. The hydraulic inflation system also buffers and regulates the fluid pressure setting the packer element to avoid overinflation of the element. In other aspects, the seal assembly may comprise a set of mud cups that are set against the borehole sidewall using a pressure differential across the seal assembly or a spring-biased seal element.

Abstract: An acoustic transducer on a downhole tool sends an acoustic wave through a sensor plate in contact with drilling fluid. Vibrations of the sensor plate are indicative of the impedance of the borehole plate that may be associated with gas influx. A processor analyzes the vibrations and uses an estimated Q of the vibrations to determine gas influx.

Abstract: The present invention provides a drilling system that utilizes the drilling fluid in a borehole to drive an apparatus to generate a high-pressure jet of fluid to facilitate the drilling operation. A pressure intensifier disposed between a drilling motor and the drill bit generates high pressure fluid jet. The drilling motor rotates the pressure intensifier. Fluid enters a high pressure chamber in the pressure intensifier at selected location during each rotation. A piston in the pressure intensifier discharges the fluid from the high pressure chamber to the drill bit bottom at a high pressure. An electrically-operated pulse frequency control device generates fluid pulses of at least two frequencies, each such frequency defining a bit of a binary system.
