chemicals used in oil-field operations

Chemicals Used in Oil-Field Operations

Drilling fluids usually contain water as the primary component. However, oil-based muds may be used for high temperature operations and for drilling highly water-sensitive formations. Oil-based muds are of two types, oil-external emulsions containing as much as 50% water in the internal phase or an oil-based fluid containing little if any water.
