Apparatus and method for well services fluid evaluation using x-rays United States Patent 07542543

07542543 is referenced by 11 patents and cites 52 patents.

A method and apparatus for determining the density and phase fractions of well services fluids is shown including an x-ray generator, a sample cell, and a radiation detector. Radiation is passed through the sample cell and fluid and the attenuated radiation signal is used to evaluate the fluid. In one embodiment, a reference radiation detector measures a filtered radiation signal and controls the acceleration voltage and/or beam current of the x-ray generator using this information. The apparatus may be permanently affixed for long term monitoring or temporarily clamped on to a pipe in production.
