Vacuum-based filtration is a viable alternative to shale shakers ///

The first line of defense in replenishing drilling fluids and separating rock particles during drilling operations is the solids control system. Foremost among such systems are shale shakers, where, through G-force vibrations, solids are filtered out for overboard discharge or treatment. The cleaned mud is then incorporated back into the active fluid system and reused to continue drilling the well. Yet, shale shakers today come with a number of limitations. The high G-forces, for example, tend to break down the drilled solids into fine particles, reducing the amount of solids removed and increasing the solids content in the drilling fluids. High volumes of mud are also lost, leading to increased drilling waste. In addition, shale shakers often result in a poor working environment, with personnel exposed to high noise levels and vibrations, as well as oil and vapor emissions.
