THE EVALUATION AND SIZING OF MUD/GAS SEPARATOR

A mud/gas separator (poor boy degasser) sizing worksheet will assist drilling personnel with the sizing calculations. The worksheet provides a quick and easy evaluation of most mud/gas separators for a specific well application. A brief discussion of other mud/gas separator considerations is provided, including separator components, testing, materials, and oil-based-mud considerations. This paper reviews and analyzes existing mud/gas separator technology and recommends separator configuration, components, design considerations, and a sizing procedure. A simple method of evaluating mud/gas separation within the separator vessel has been developed as a basis for the sizing procedure.

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.
