Drilling fluids have a continuous liquid phase and are modified with various chemical additives, both liquid and solid, to align the performance of the drilling fluid to the drilling conditions. However, all fluid types must possess some common characteristics. More than one WBF system is typically used when drilling the same well because various formulations of fluids are required to be able to accurately meet the technical physiochemical properties required in each section of the well. The fluid composition may also need to be continually modified within each hole section.
