WHAT IS THE PURPOSE OF A DRILLING MUD?
The purpose of a drilling mud can be broken into nine basic functions:

RIG PREPARATION FOR DRILLING OIL-BASED MUD
Oil-based drilling fluids have long been recognized as a sound technical answer to problems encountered in deep-hot holes and, more recently, to stabilize boreholes with thick intervals of reactive clay formations. However, oil-based mud product development was slowing down until the introduction of low toxicity base oils in the late seventies created a need for new investigations. This innovation sparked a resurgence of oil mud research and development which has resulted in oil-based mud (OBM) systems being used routinely in many active drilling areas worldwide.

Mixing System for Fracturing Fluid
The mixing system makes possible improvements and presents case histories of field applications.
Fracturing operations have been improved by
(1) Mixing fracturing slurries under microprocessor control,
(2) Applying new baffle and agitator design concepts, and
(3) Using new methods for achieving rapid material wetting.
