Drilling Fluids laboratories may also do the following tests:

Rheological Testing: Measures the flow properties of drilling fluids essential for predicting performance under various pressure and temperature conditions Testing
Filtration Rate Testing: Determines the ability of the fluid to prevent fluid loss to the formation crucial for maintaining well stability Testing
Lubricity Testing: Assesses the lubrication properties of the fluid which helps in reducing wear and tear on the drilling equipment Testing
Corrosion Testing: Evaluates the potential of drilling fluids to cause corrosion on drilling equipment ensuring material compatibility and longevity Testing
