Abstract: Systems for examining a material comprising: an electromagnetic radiation source; a dielectric contrast analysis structure comprising: a bulk dielectric substance; a plurality of receptacles in the bulk dielectric substance for receiving the material; and an electromagnetic radiation detector, wherein the dielectric contrast analysis structure is between the electromagnetic radiation source and the electromagnetic radiation detector. Wherein the plurality of receptacles are substantially parallel with one another and are disposed in a dielectric contrast analysis structure that is disposed in a pipe. Wherein the dielectric contrast analysis structure comprises: a bulk dielectric substance having a first end, a second end, and the plurality of receptacles disposed within the bulk dielectric substance, wherein a flow path of the material through the receptacles is from the first end of the bulk dielectric substance to the second end of the bulk dielectric substance.

Abstract: Methods and apparatus for examining a material are provided. One example method generally includes disposing the material in a dielectric contrast analysis structure, wherein the dielectric contrast analysis structure comprises a bulk dielectric substance and a plurality of receptacles in the bulk dielectric substance, wherein the material is disposed in one or more of the plurality of receptacles; exposing the dielectric contrast analysis structure to incident electromagnetic radiation; detecting resultant radiation from the exposed dielectric contrast analysis structure; and analyzing the detected resultant radiation to estimate at least one of a phase fraction and a phase distribution in the material. One example system generally includes an electromagnetic radiation source; a dielectric contrast analysis structure comprising a bulk dielectric substance and a plurality of receptacles in the bulk dielectric substance for receiving the material; and an electromagnetic radiation detector, wherein the analysis structure is between the radiation source and the detector.

Abstract: A method for estimating a flow rate of a material (e.g., a multiphase fluid) may include: flowing the material through one or more of a plurality of receptacles of a dielectric contrast analysis structure that includes: a bulk dielectric substance and the plurality of receptacles in the bulk dielectric substance; exposing the dielectric contrast analysis structure to incident electromagnetic radiation; detecting and analyzing a resultant electromagnetic radiation from the exposed dielectric contrast analysis structure to yield a phase fraction in the material and a phase distribution in the material; measuring a differential pressure across the dielectric contrast analysis structure; and estimating the flow rate of the material using the differential pressure, the phase fraction, and the phase distribution in the material.

Abstract: Embodiments of an invention disclosed herein relate to methods for performing formation evaluation of a formation or formation's surrounding to identify and characterize the abundance and morphology of non-ionic conductor grains, “c-grains”, within the formations that are evaluated by formation evaluation (FE) tools. The methods and related systems as disclosed herein are directed to correcting any existing FE logs that can be adversely affected by the presence of c-grains in the detection volume of FE tools, and/or obtaining new FE information that is unavailable by the application of existing FE methods.
