Abstract: Techniques described herein relate to a method for identifying downhole conditions during a drilling operation using a vibratory separator. The method includes calibrating a sensor system attached to the vibratory separator by periodically measuring the G-force acting on the vibratory separator functioning under steady-state operating parameters. The method also includes determining the relationship between the G-force acting on the vibratory separator and the flow rate and rate of penetration (ROP) for the drilling operation by measuring the G-force acting on the vibratory separator functioning under different non-steady-state operating parameters. The method further includes determining an expected total basket weight for each G-force measurement using the G-force/flow rate/ROP relationship, monitoring a current total basket weight of the vibratory separator functioning under current operating parameters, and identifying a downhole condition if the current total basket weight is greater or less than the expected total basket weight for the current operating parameters.

Abstract: An intrinsically-safe sensor system, as well as a method for assembling the intrinsically-safe sensor system and a method for monitoring sound corresponding to a source using the intrinsically-safe sensor system, are provided herein. The intrinsically-safe sensor system includes a number of sensors, including a microphone, as well as a processor for processing sensor data obtained from the sensors. The intrinsically-safe sensor system also includes a memory component for storing the sensor data obtained from the sensors, a power source, a communication connection for communicably coupling the intrinsically-safe sensor system to a remote computing system, and a connector including internal and external connection regions for internally and/or externally connecting one or more additional devices to the intrinsically-safe sensor system on demand. The intrinsically-safe sensor system further includes an enclosure, as well as potting material for encapsulating an internal region of the intrinsically-safe sensor system that resides within the enclosure.
