Abstract: Processing electronics provide flow data acquisition and telemetry for multiphase flow tomographic ultrasonic transceiver arrays. The processing electronics forms pulse drive signals to cause a tomographic pulse sequence to be emitted. Selected ones of an array of the ultrasonic transceivers emit ultrasonic energy in the tomographic pulse sequence for travel through the multiphase flow. The selected transmitting transceiver is isolated while transmitting it, and the remaining the transceivers are enabled to receive measures of the emitted pulse is after travel through the multiphase flow.

Abstract: Systems and methods for determining characteristics of a fluid in a subterranean well include providing a production pipe extending into the subterranean well to convey the fluids from within the subterranean well to an earth's surface. An x-ray source is located on a first side of the production pipe. An x-ray beam is directed into the production pipe, into the fluids, and out of an opposite side of the production pipe as a resulting beam, with the x-ray source. A level of attenuation of the resulting beam is detected with an attenuation detector located on an opposite side of the production pipe. A fluorescence spectra of the resulting beam is detected with a scattered fluorescence detector located on the opposite side of the production pipe. A fluorescence peak of the resulting beam is detected with a peak fluorescence detector located on the opposite side of the production pipe.

Abstract: Processing electronics provide flow data acquisition and telemetry for multiphase flow tomographic arrays. The processing electronics convert sensed flow condition data obtained by ultrasonic transceiver tomography arrays into a serial digital data to minimize both the number of external feedthroughs and also the bandwidth required for transmission. The processing electronics also sends the full measured waveforms from each of the transceivers in the tomographic arrays.

Abstract: Tomographic reconstruction is performed of cross-sectional images of downhole or surface multiphase flows containing water (brine), oil, and gas phases. Measures are obtained of digital transmission (or analog attenuation) and also of analog transit time to form two views of the same cross sectional flow in a location of interest in a flow conduit. The measures are then merged by synthesizing a composite image of the multiphase flows. Rather than performing a complex tomographic reconstruction requiring a large number of calculations, measures are also obtained directly from the tomographic pattern which can be used to reconstruct an approximation of the cross sectional flow by the superposition of circles of variable position, radius and density representing flow patterns.

Abstract: Ultrasound tomography arrays and vortex shedding devices are provided which measure average flow velocity through Doppler shift of the fluid as well as cross sectional multiphase fluid composition in pipe or tubing conduits. Multiple tomographic arrays in conjunction with correlation of sensed flow patterns in time provided determination of flow velocity as well as cross sectional multiphase fluid composition. The tomographic arrays may be arranged in a skewed or slanted plane to measure velocity fluctuations downstream of a vortex shedding device where the period and amplitude of the fluctuations is correlated with the mass flow of the fluid. Additionally, the tomographic arrays provide the relative composition of the multiphase fluid. The multiple arrays together with correlation to determine velocity fluctuations downstream of a vortex shedding device where the period and amplitude of the fluctuations is correlated with the mass flow of the fluid.

Abstract: A system and method for downhole data communication using an infrasound wave generator and receivers. The infrasound waves have a low frequency and a wavelength that is much larger than the transverse dimensions of the well. When the infrasound waves are directed down the well, the well will act as a wave guide for low frequency excitations. The receivers are operatively connected to inflow valves and other downhole equipment, and receive the infrasound waves. If the waves are of a predetermined frequency, the receivers command the valves to open or close, or otherwise control downhole equipment. The infrasound waves can also be used to probe well geometry and to identify fluid properties within the well.
