Shaker fluid level automatic control

A shaker used for separating used drilling mud at a well-site, the shaker comprising:

• a screen layer disposed within the basket to provide filtering, the screen layer defining an above screen layer to retain cuttings and other debris and a below screen layer for filtered mud fluid;
• at least two motors providing vibratory action to the basket, each of the at least two motors having a motor weight;
• one or more sensors to collect a set of run-time measurements for the shaker while the shaker is in operation, the set of run-time measurements reflecting a motor speed for each of the at least two motors or at least one of a shaker vibration dominant frequency, a shaker current inclination, and a misalignment of motor weights;
• and
• a controller programmed with instructions representative of actions based on an empirical model derived previously from an operational shaker, the actions to provide run-time adjustments of the shaker to affect a beach position on the screen layer.

• one or more sensors to collect a set of run-time measurements for the shaker while the shaker is in operation, the set of run-time measurements reflecting using one or more accelerometers associated with the screen layer to obtain high frequency vibrations associated with the screen layer that are indicative of the beach position;
• and
• a controller programmed with instructions representative of actions based on an empirical model derived previously from an operational shaker, the actions to provide run-time adjustments of the shaker to affect a beach position on the screen layer.
