摘要： A downhole receiver for gathering seismic and sonic data from inside a borehole includes a substantially tubular housing adapted for axial connection to a tool string, and one or more sensors. A damping element is provided to flexibly couple each sensor to the tubular housing. An actuator extends the one or more sensors substantially radially with respect to the tubular housing to clamp the sensors against the wall of the borehole. In selected embodiments, the sensors may be one or multiple component geophones, accelerometers, hydrophones, vibrometers, or the like.

摘要： A downhole tool for gathering formation data from inside a borehole includes a substantially tubular housing adapted for axial connection to a drill string and multiple sensors coupled to the tubular housing. The sensors include a first pair of sensors aligned along a first axis and adapted to measure a spatial derivative along the first axis, a second pair of sensors aligned along a second axis and adapted to measure a spatial derivative along the second axis, and a third pair of sensors aligned along a third axis and adapted to measure a spatial derivative along the third axis. In selected embodiments, the spatial derivatives are used to differentiate seismic or sonic compression and shear waves measured in a downhole environment.

摘要： Concealed carry bib-overalls for providing concealed pockets for placing firearms for concealed carry transport. The concealed carry bib-overalls may comprise a pair of overalls and one or more concealed pockets. The pair of overalls may be a garment comprising a bib which is adapted to extend vertically in front of a user's abdomen. The bib may be held upright by suspenders. The suspenders may be adapted to couple to the top of the bib after passing over a user's shoulders. The concealed pockets may be located on the rear of the bib where the concealed pockets may be hidden from view. The one or more concealed pockets may be adapted to conceal a handgun. A user may produce the handgun from within the concealed pockets by releasing a gap fastener and extracting the handgun through one or more access gaps.

摘要： An apparatus and method for seismic measurement-while-drilling comprises at least one of a downhole seismic receiver or a downhole seismic source deployed in a telemetry drill string. Preferably both a downhole receiver and a downhole source are deployed in the drill string, the source and receiver being fixed at a pre-determined distance from each other. As drilling progresses into a subterranean formation, a first seismic shot is performed at a first level, producing a model characteristic of the subterranean formation, and at least one subsequent seismic shot is performed at at least one subsequent level, producing at least a second model characteristic of the subterranean formation. The first and at least the second model are used in combination to evaluate the subterranean formation and to evaluate the progress of the drill string relative to the formation.
