Abstract: A gel-filled seismic streamer containing a hydrophone housing which isolates a hydrophone element from shear waves and mechanical forces but sensitive to pressure waves. In one embodiment, the gel-filled streamers contains a hydrophone housing with an air pocket at each end for isolating a pressure sensitive hydrophone element from mechanical noise generated by cable movement during seismic data acquisition operations. The hydrophone housing further provides and a protective case to isolate a pressure-sensitive hydrophone element from shear waves. An inlet formed in the protective hydrophone housing enables pressure waves to be communicated to the pressure sensitive hydrophone element inside of the housing. An alternative hydrophone housing for deployment inside of a streamer is also disclosed which fixably positions a positioning hydrophone or seismic hydrophone within the housing using rubber supports.

Abstract: A gamma densitometer window comprises a plate of non-metallic, preferably gamma transparent, material. The window further comprises a metallic frame member fitted around the outer edge of the plate and adapted to pre-load the plate with a compressive stress that is sufficiently high such that the sum of the compressive stress, tensile stress and shear stress components generated in the plate under high-pressure conditions is always compressive. The window is fabricated by shrink fitting the metallic frame member around the outer edge of the plate at a shrink-fit temperature such that the metallic frame member applies a compressive stress to the plate at any temperature below the shrink-fit temperature.

Abstract: A method of measuring the permittivity and/or conductivity of a multiphase fluid flowing through a conduit is provided. The method includes the steps of measuring the signal from a first electromagnetic transmitter to a first electromagnetic receiver separated by a first distance, measuring the signal from the first electromagnetic transmitter to a second electromagnetic receiver separated by a second distance, measuring the signal from a second electromagnetic transmitter to the first electromagnetic receiver separated by a distance substantially equal to the second distance, measuring the signal from the second electromagnetic transmitter to the second electromagnetic receiver separated by a distance substantially equal to the first distance, and wherein the first and second distances are substantially different. This is followed by the step of combining the four signals to obtain a measurement of the phase-shift and amplitude-attenuation substantially independent of the gain values applied to the receivers and transmitters to provide an estimate of the mixture permittivity and/or conductivity of the multiphase fluid.

Abstract: An acoustic emitter for coupling in series in a marine seismic streamer is provided with an annular housing and an annular piezoelectric emitting element positioned coaxially within the housing. This form of construction permits the electrical or electro-optical transmission line which normally runs along the axis of the streamer to pass through the center of the emitting element, while also permitting the emitter to be spooled with the streamer.
