Evaluate The Efficiency Of Solids Control Equipment

The volume and type of solids in a drilling mud system can adversely affect mud properties, reduce penetration rates, cause damage to drilling equipment, and increase total drilling costs. Efficiency controlling the solids content of the mud system is an important phase of an efficient and cost-effective drilling program. The three basic methods of removing solids are dilution and/or displacement of whole mud, settling and mechanical solids-control equipment.

Solids Control Through Economic Evaluation of Mechanical Equipment

Proper application and utilization of mechanical solids control equipment enables the driller to maintain the desired drilling fluid properties which in turn makes it possible for the drilling operation to be carried out in an efficient and possible for the drilling operation to be carried out in an efficient and economical manner.

Optimization of the Solids Control Equipment System

The combination of fast drilling, gumbo clay, and conventional solids control equipment operations can create a variety of issues:

  • High losses of drilling fluid through the solids control units.
  • High volume of dilution.
  • High volumes of fluid processed requiring strictly regulated disposal to protect the environment.
  • Continuous plugging of the mesh in the solids control units.
  • Increase in the consumption of screens.
  • Fluid overflow due to plugging of the screw conveyors.
  • Poor supervision of the solids control units.
  • Increased operating costs.

Solids Control Equipment: Shaker, Mud Cleaner, Desilter, etc.

Control of drilled solids from the mud is one of the major functions of a drilling fluid circulating system. Several types of solids control equipment are used to accomplish this task, including screening equipment( shale shaker ), hydrocyclones ( mud cleaner, decanter, desilter ), and decanter centrifuges.
