An acoustic sand monitor system includes an exciter assembly and a receiver that are configured to be coupled to an accumulator vessel. Separating equipment separates sand from a fluid stream produced by a well. The accumulator vessel collects the sand separated from the fluid stream. The exciter assembly causes vibrations of the accumulator vessel and the receiver measures audio signals generated by the vibrations of the accumulator vessel. A control system analyzes the audio signal to determine the amount of sand collected in the accumulator vessel.

An optical strain gauge system measures strain on the exterior surface of a pipe to identify areas of wear on the interior surface of the pipe. The optical strain gauge system comprises an optical sensing interrogator and at least one optical fiber. The optical sensing interrogator comprises a light source and a light sensor. The at least one optical fiber includes fiber Bragg gratings along the length of the optical fiber. The optical fiber is arranged on the exterior surface of the pipe with the fiber Bragg gratings forming a two-dimensional array of points at which strain measurements are obtained. The two-dimensional array of strain measurement points provides an accurate assessment of the strains on the exterior of the pipe which can be used to identify areas of wear on the interior surface of the pipe.

A test apparatus for qualifying compositions used to reduce scale deposition in fluid, e.g., wax deposition in crude oil, is disclosed. The test apparatus includes a first reservoir capable of holding a first fluid, and a second rotatable reservoir disposed within the first reservoir, the second reservoir capable of holding a second fluid. The apparatus includes a fluid inlet through which the second fluid enters the second reservoir, and a fluid outlet through which the second fluid exits the second reservoir, wherein a bottom surface of the second rotatable reservoir is configured to be at least partially submerged in the first fluid so that precipitate from the first fluid can be deposited thereon.
