Abstract: A reaming tool vacuum assembly comprising: a reaming tool comprising a reaming bit, the reaming bit comprising: a tip end; a base end; a plurality of flutes tapered toward the tip end; a plurality of apertures positioned between the plurality of flutes, wherein the plurality of apertures define a plurality of openings to an interior chamber of the reaming bit; a first rigid tube positioned in the interior chamber of the reaming bit, wherein the reaming bit is rotatable around a longitudinal axis of the first rigid tube and independent of the first rigid tube; and a vacuum to provide suction in the interior chamber of the reaming bit via the first rigid tube.

Abstract: An instrument and method for analyzing a gas leak. The instrument can obtain a time series of spectra from a scene. The instrument can compare spectra from different times to determine a property of a gas cloud within the scene. The instrument can estimate the column density of the gas cloud at one or more locations within the scene. The instrument can estimate the total quantity of gas in the cloud. The instrument can estimate the amount of gas which has left the field of view of the instrument. The instrument can also estimate the amount of gas in the cloud which has dropped below the sensitivity limit of the instrument.

Abstract: An infrared (IR) imaging system for determining a concentration of a target species in an object is disclosed. The imaging system can include an optical system including a focal plane array (FPA) unit behind an optical window. The optical system can have components defining at least two optical channels thereof, said at least two optical channels being spatially and spectrally different from one another. Each of the at least two optical channels can be positioned to transfer IR radiation incident on the optical system towards the optical FPA. The system can include a processing unit containing a processor that can be configured to acquire multispectral optical data representing said target species from the IR radiation received at the optical FPA. One or more of the optical channels may be used in detecting objects on or near the optical window, to avoid false detections of said target species.

Abstract: A ball valve assembly for a fracturing (frac) fluid end. The ball valve assembly includes a seat that is adapted to engaged with the frac fluid end inside of at least one chamber defined by the frac fluid end. The ball valve assembly also includes a seal that is operably engaged with the seat to prevent fluid from escaping around the seat. The ball valve assembly also includes a ball valve that is operably engageable inside of the seat. During operation, the ball valve is moveable between a seated position and a disengaged position relative to the seat via at least plunger of the frac fluid end to allow the fluid to travel from an intake chamber of the frac fluid end towards a discharge chamber of the frac fluid end.
