    摘要： An electronic noise filtration system for use in improving the signal to noise ratio of acoustic data transmitted from a downhole transducer in a measurement while drilling system. Signals from a pair of receiving acoustic transducers located in the mud flow path directed downhole are input to a differencing amplifier. The RMS output of the amplifier is converted from an analog to a digital signal and then processed by a computer programmed with a least mean squares technique for minimizing the signal. The input from one receiving transducer is routed through a delay line wherein a programmable clock controls the timing of the signal delay. The delay time is controlled and adjusted by the computer's calculation of the frequency with which the clock should drive the delay line to minimize the difference between the two received transducer signals. This function minimizes ambient noise in the acoustic transmission line formed by the column of drilling fluids when no data transmissions are being made. Computer analysis and adjustment of the delay time effectively maximizes filtration of acoustic noise due to mud pump pulses and or reflections of noise from the pump thereof without limitation to the geometrical configuration or other noise related variables.

    摘要： A disclosed downhole telemetry system employs an array of near-field electromagnetic communication devices to relay information along a tubular in a borehole. In some embodiments, the devices are permanently attached to pipe joints without requiring any structural modification of the pipe joints. As the pipe joints are strung together in the normal fashion to form a tubular, the devices automatically establish a wireless communications path between an uphole terminus device and any downhole sensors or tools. The devices can include built-in sensors to provide distributed sensing of parameters such as temperature and pressure. In some embodiments the device array incorporates redundancy to minimize the chance of a communications network failure. The device array has applications for logging-while-drilling, production testing, well completion, reservoir monitoring, and well control.

    摘要： Borehole data presentation systems and methods that facilitate communication of volumetric logging data to a surface processing system for presentation to a driller or other user interested in visualizing the formations surrounding a borehole. The disclosed systems optionally tailor the telemetry stream to match the chosen display technique, thereby maximizing the logging system utility for the driller. Variable opacity of certain data regions or certain data discontinuities greatly facilitates data comprehension, particularly when true three-dimensional display technologies are employed. Holographic or stereoscopic display technologies may be employed to show the three-dimensional dependence of measured formation properties such as resistivity, density, and porosity. Alternatively, the radial axis can be used to represent a formation parameter value, thereby enabling cylindrical cross-plots of multiple measurements. The user can control viewing position and orientation to more fully explore the three dimensional representation.

    摘要： Treating a subterranean formation includes injecting a magnetically permeable material into the formation and energizing the magnetically permeable material using electromagnetic radiation. The magnetically permeable material reacts to the electromagnetic radiation by producing heat. In some embodiments, a fracturing fluid is made magnetically permeable, injected into the formation to fracture the formation, and heated in response to electromagnetic radiation applied to the magnetically permeable material. In some embodiments, electromagnetically heated material is caused to explode. In some embodiments, the magnetically permeable material is tracked or monitored for fluid or fracture propagation. A system includes a fluid treatment tool disposed on a tubing string for injecting magnetically permeable material and an electromagnetic wave generator disposed on the tubing string proximate the fluid treatment apparatus for applying electromagnetic radiation to the magnetically permeable material.
