Oil-Water Ratio (OWR) Change
Oil-Water Ratio (OWR) refers to the proportion of oil to water in drilling fluids. When water enters an oil-based mud, the OWR decreases, and to raise the OWR, additional oil must be added.
This property is crucial for maintaining the stability of weight material particles in suspension during drilling operations.
