    Abstract: A frac plug system, downhole tool and method of securing a frac plug system in a wellbore in a formation. A mandrel includes a first end and a second end. A setting assembly is coupled to the mandrel at the first end, and an anchor is arranged at the second end of the mandrel and receptive to the setting assembly. The anchor is settable to engage the wellbore. A bottom sub is arranged at the second end of the mandrel and includes a first member movable relative to the mandrel. A gas generates a pressure to shift the first member along the mandrel to move the anchor against the setting assembly, securing the setting assembly in the wellbore via radial deployment of the anchor. The mandrel is separated from the bottom sub to leave the setting assembly and the anchor in the wellbore.

    Abstract: A shank assembly includes a neck portion, a shank portion defining a cylindrical aperture extending therethrough, and an anchor tube secured to the neck portion and extending through the shank portion, the anchor tube and the shank portion defining an annular cavity therebetween, and an electronics module disposed within the annular cavity. The annular cavity is formed to maximize space for electronics while maintaining structural integrity of a crown and shank of an earth-boring tool. A method includes disposing the anchor tube of a shank assembly through the cylindrical aperture and securing the anchor tube to a neck portion of the shank assembly, disposing the electronics module within the annular cavity, and disposing the shank portion and anchor tube of the shank assembly at least partially within a crown of the earth-boring tool such that annular cavity extends into the crown in an axial direction a distance that is between about 10% and about 80% of an overall axial length of the crown.

    Abstract: A method of in situ ultrasonic flow meter validation includes receiving data characterizing first signal diagnostics and data characterizing a first speed of a first acoustic signal through a gas mixture along a first path in a pipe. The first speed of the first acoustic signal is detected by a first channel of an ultrasonic flow meter including a first pair of transducers that are separated by a first path length of the first path. The gas mixture is configured to flow along a flow path in the pipe. The method also includes determining a status associated with the ultrasonic flow meter based on the data characterizing the first signal diagnostics and/or a difference between the first speed of the first acoustic signal and an independently calculated speed of sound. The speed of sound is calculated based on one or more properties of the gas mixture.

    Abstract: Methods, systems, devices, and products for hydrocarbon tubular evaluation. Methods comprise conveying the logging tool in the tubular with a carrier; inducing with a transmitter a horizontal shear (SH) wave; identifying higher order SH mode signals received at a plurality of offset receivers responsive to a higher order SH mode engendered by the horizontal shear (SH) wave; estimating a dominant frequency for higher order SH mode from the higher order SH mode signals; estimating a group velocity for the higher order SH mode from the higher order SH mode signals; and estimating a tubular parameter using the dominant frequency and the group velocity. The tubular parameter may be at least tubular thickness. The method includes estimating the tubular parameter independent of the fundamental horizontal shear wave mode (SHO).

    Abstract: A method of analyzing a well sample for a well treatment additive includes contacting the sample with functionalized metallic nanoparticles that contain metallic nanoparticles functionalized with a functional group including a cyano group, a thiol group, a carboxyl group, an amino group, a boronic acid group, an aza group, an ether group, a hydroxyl group, or a combination including at least one of the foregoing; irradiating the sample contacted with the functionalized metallic nanoparticles with electromagnetic radiation at a selected energy level; measuring a Raman spectrum emitted from the sample; and determining presence, type or concentration of the well treatment additive in the sample from the Raman spectrum.
