Abstract: Methods, systems, devices, and products for manufacturing an electrical assembly, such as a completed downhole circuit board, for use in well logging. Methods include attaching an electrical component to a printed circuit board by mechanically fastening the electrical component to the printed circuit board. Methods may include using a laser to attach a plurality of legs to contact surfaces. Methods may include applying light from the laser to a material of the printed circuit board to produce heat, including mitigating reflection of the light from the material. Methods include forming a connection between a first electrical component of the electrical assembly and a second electrical component of the electrical assembly by causing heating of an additive manufacturing material by applying light from a laser. The connection may be at least one of: i) an electrical connection; ii) a structural connection; iii) an electrical insulation.

Abstract: Methods, systems, and devices for determining a parameter of interest of downhole fluid using an acoustic assembly comprising a single solid acoustic transmission medium having a face immersed in the downhole fluid. Methods include using characteristics of a plurality of acoustic pulse reflections from a solid-liquid interface at the face of the solid acoustic transmission medium to estimate the parameter of interest in near real-time. The characteristics may comprise a corresponding reflection amplitude and the corresponding unique angle of reflection for each acoustic pulse reflection. Methods may include generating a two dimensional data set from measured characteristics, generating a curve by performing data fitting on the two dimensional data set, and using the reciprocal slope of the curve to estimate the parameter of interest. Methods may include estimating time-dependent values for the parameter of interest substantially continuously while the acoustic assembly is on a single logging run in the borehole.

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.
