    Abstract: Methods, systems, devices, and products for estimating at least one parameter of interest of a volume of interest of an earth formation using nuclear radiation based measurements. Logging tools include a limited aperture collimated radiation beam source, detectors, and at least one processor configured to take measurements. The source is configured to emit a beam of radiation radially from the logging tool into an elongated volume of interest outside the wellbore such that the beam penetrates a plurality of zones of the volume of interest. Each zone represents a range of radial depths corresponding to a respective infrastructure component associated with the wellbore, such as nested tubulars. Each detector has a unique angle of detection and is configured to generate measurement information in response to spatially coherent backscattered gamma rays. Each detector is associated with scattering events at one of the plurality of zones.

    Abstract: Evaluating a fluid, including transmitting a light beam through the fluid to a detector while oscillating a path length traveled through the fluid by the light beam at a first frequency of oscillation; measuring a time-dependent intensity of incident light at the detector responsive to an interaction of the light beam with the fluid to produce a time-dependent intensity signal; filtering the time-dependent intensity signal to recover a path-dependent signal oscillating at the first frequency and indicative of an absorbance property of the fluid; and estimating a parameter of interest of the fluid using the path-dependent signal. The time-dependent intensity may be indicative of the true absorbance at multiple wavelengths of the fluid or fluids over the maximum path length difference so as to permit quantification of the percentages of each of these fluids. Filtering may include frequency filtering alone or using a phase-sensitive lock-in amplifier.

    Abstract: Methods, systems, devices, and products for taking a downhole measurement are presented. The method may include cooling a sensor in a borehole intersecting an earth formation using an electrocaloric material associated with the sensor, wherein the sensor is responsive to a downhole parameter. The method may further include applying an electric field to the electrocaloric material to generate a giant electrocaloric effect. The method may include selecting dimensions, composition, and Curie temperature of the electrocaloric material and characteristics of the electric field sufficient to reduce the nominal temperature of the sensor by at least 20 degrees Celsius, which may result in the sensor being proximate to a target temperature within the nominal operational temperature range of the sensor.

    Abstract: A method and system for evaluating both fluid type and fluid flow downhole by applying thermal energy in a flow of the fluid, and monitoring downstream temperature over time to generate a temperature profile. The type of fluid being evaluated can be determined by comparing the measured temperature profile to profiles over time of known fluids because these profiles depend upon these fluids' thermal diffusivities and flow rates. Further, stratified flow in a deviated wellbore can be analyzed by conducting the fluid evaluation at different radial locations in the flow stream so that the presence of water, liquid hydrocarbons, and gas can he identified. The system can include a pivoting arm that selectively spans the wellbore diameter, and which includes multiple thermal sources, each with corresponding thermal sensor, that are spaced along the arm. A frame can be provided for each of the sources and sensors, which is automatically self-oriented along the direction of fluid flow like a weather vane.
