Shaker vibration and downhole cuttings measurement analysis and processing

A method comprising:

• performing a downhole operation in a borehole;
• capturing, during the downhole operation, downhole particles and drilling mud at the surface from the borehole into a screen of at least one shaker;
• shaking the screen to emit vibrations to separate the downhole particles from the drilling mud;
• defining a vibration limit for a normal operating condition of the at least one shaker;
• setting a vibration fault threshold based on the vibration limit for the normal operating condition;
• monitoring, using at least one sensor, the vibrations over time;
• in response to the vibrations exceeding the vibration fault threshold, determining there is a fault condition for the at least one shaker;
• determining a measured volume of the downhole particles on the screen at a time corresponding to when the vibrations are monitored;
• in response to determining a difference between the measured volume and a projected volume of anticipated downhole particles exceeds a volume error threshold and in response to the vibrations not exceeding the vibration fault threshold, outputting, determining that a downhole condition occurring based on the measured volume;
• monitoring number of revolutions per unit of time of a motor of the at least one shaker causing the shaking;
• and
• in response to determining the number of revolutions per unit of time exceed a revolution threshold and in response to the vibrations exceeding the vibration fault threshold, determining that the fault condition comprises a fault in the motor.

A system comprising:

• a shaker screen onto which downhole particles and fluid from a borehole are to be placed, the downhole particles a product of a downhole operation;
• at least one shaker to vibrate the shaker screen to separate the downhole particles from the fluid;
• at least one sensor on the at least one shaker to monitor vibrations of the at least one shaker over time, wherein the at least one sensor comprises at least one of a strain gauge and a multi-axis accelerometer;
• a device to,
• define a vibration limit for a normal operating condition of the at least one shaker;
• set a vibration fault threshold based on the vibration limit for the normal operating condition;
• set a vibration maintenance threshold based on the vibration limit for the normal operating condition;
• trigger an alarm for predictive maintenance of the at least one shaker, in response to the vibrations exceeding the vibration maintenance threshold;
• and
• determine there is a fault condition for the at least one shaker, in response to the vibrations exceeding the vibration fault threshold.
