摘要： In one embodiment, a wellbore power generation method includes causing a fluid to flow through a downhole turbine, and causing the turbine to rotate a generator. At least one of a turbine configuration and a flow rate of the fluid is selected to cause the downhole turbine to operate near its runaway speed, such that changes in load applied to the generator do not substantially affect a rotation rate of the downhole turbine.

摘要： A drill has a tubular outer housing and a tubular inner housing. The inner housing is movable between extended and retracted positions. A pneumatic motor with a chuck mounts to the inner housing. Air pressure is delivered to annular pistons to cause the inner housing to extend and retract. Also, an annular hydraulic chamber with a variable orifice bypass controls the rate of feed. A processor records the total number of holes being drilled as well as recording the time duration for each hole.

摘要： In one embodiment, a wellbore completion method includes disposing an expandable screen into a well bore and disposing a fluid into an annular space between a wall of the wellbore and the expandable screen. The fluid contains a plurality of near neutrally-buoyant particles. The method further includes radially expanding the screen, whereby the near neutrally-buoyant particles exert a force against the wall of the wellbore.

摘要： In the computer interpretation of seismic data, the critical first step is to identify the general class of an unknown event. For example, the classification might be: teleseismic, regional, local, vehicular, or noise. Self-organizing neural networks (SONNs) can be used for classifying such events. Both Kohonen and Adaptive Resonance Theory (ART) SONNs are useful for this purpose. Given the detection of a seismic event and the corresponding signal, computation is made of: the time-frequency distribution, its binary representation, and finally a shift-invariant representation, which is the magnitude of the two-dimensional Fourier transform (2-D FFT) of the binary time-frequency distribution. This pre-processed input is fed into the SONNs. These neural networks are able to group events that look similar. The ART SONN has an advantage in classifying the event because the types of cluster groups do not need to be pre-defined. The results from the SONNs together with an expert seismologist's classification are then used to derive event classification probabilities.
