The circulating system pumps drilling mud in and back out of the well hole. Drilling mud is stored in several steel mud tanks on the ground beside the rig.

Effective rotary steerable drilling systems overcome most of the problems with steerable motors by providing continuos pipe rotation while drilling. This is accomplished, with the tool reported on in this paper, with a non-rotating steerable sleeve containing three extendable pads that push against the borehole wall.

Shale shakers, often referred to as “oilfield shakers’ in the industry. Shale shakers are part of a Solids control System used in oil and gas drilling operations to Separate the Solid material removed from the well bore. Cuttings, referred to as “solids”, by the drilling operations from the drilling fluid, commonly referred to as “mud”.

A simple and economical surface solids control method to complement the downhole systems becomes necessary when we desire to reduce viscosity, yield point, gel strength, total solids, concentration of drilled solids, and low micron-size material. This aim will be achieved when we are able to partially reject the undesirable materials from the drilling fluid system.
