    Abstract: A system, method and device may be used to monitor conditions in a borehole. Well tubing and casing act as a conductive pair for delivering power to one or more downhole active sensors. At the surface, power and signal are isolated so that the same conductive pair may act to transmit the sensor signals to the surface. In an embodiment, the sensor signals are RF signals and the surface electronics demodulate the RF signals from the sensor power.

    Abstract: A pressure sensor for sensing pressure of a fluid includes a tubular housing that has a first capacitor plate segment and a second capacitor plate segment. Each of the first capacitor plate segment and the second capacitor plate segment includes a respective substantially planar inner surface. The pressure sensor also includes an anvil positioned within the tubular housing. The anvil and the tubular housing function as opposite terminals of a variable capacitor. A first capacitor plate side of the anvil and the first capacitor plate segment face each other and have a first gap therebetween. A second capacitor plate side of the anvil and the second capacitor plate segment face each other and have a second gap therebetween. Capacitance of the variable capacitor changes in response to a first change in a size of the first gap and a second change in a size of the second gap.

    Abstract: A method and apparatus for recovering fine solids from a liquid feed suspension is disclosed. The apparatus has an operating cycle including a concentration part of the cycle in which solids present in the feed suspension are concentrated and a backwash part of the cycle in which supply of feed suspension to the concentrator is interrupted, the concentrator comprises a shell (11), and a plurality of elastic, hollow, microporous, polymer fibers (12) being fixed at their ends within the shell (11). Pressurized feed suspension is supplied to the outside of the fibers during said concentration part of the cycle and the filtrate may be withdrawn from the fiber lumens during the operating cycle. During the backwash cycle the concentration part of the cycle is terminated by ceasing supply of feed to said exterior surface of the fibers (12). The shell (11) is then sealed and the remaining filtrate removed from the lumens. A source of fluid under pressure is then applied to said lumens before, at the same time as, or just after opening the shell (11) to atmosphere, to cause explosive decompression through the walls of the fibers (12) whereby the fluid under pressure passes through said walls. The pressure level in said lumens is maintained at a predetermined value for a sufficient time following said decompression to cause substantial portions of solids lodged within and/or on the fiber walls to be dislodged. The dislodged contaminant matter is then washed away by the application of a flow of liquid over the surface of the fiber walls; and the concentration part of the operating cycle is recommended by introducing the supply of feed suspension to said exterior surface of said fibers (12).

    Abstract: An improved method and apparatus for offshore drilling is described which is particularly useful for drilling in deep water from a floating surface vessel. Drilling fluid is introduced into a drill string extending from the vessel into a wellbore in the floor of the body of water. In order to maintain a controlled hydrostatic pressure within the riser, drilling fluids are diverted from the lower end of the riser and are either discharged into the body of water or pumped to the surface through a return conduit adjacent the riser.
