Viscosity is a measure of a fluid’s resistance to flow and is an important factor to consider in mining operations and drilling. This article discusses how to increase the viscosity of drilling mud.
Things That Increase The Viscosity of Drilling Mud
- Additives: Various additives can be used to increase the viscosity of drilling mud, such as polymer fluids, lignite, bentonite, and other chemical agents. These additives improve the hole-cleaning properties of the drilling fluid, as well as its plastic viscosity and gel strength.
- Shear: Increasing the shear of drilling mud by using mud pumps and drill bits can also increase its viscosity. Shear thins the drilling fluid, which improves its ability to carry cuttings out of the hole and aids with fluid loss control, proper lubrication between the drill bit and formation, and drill cuttings transport.
- Temperature: Generally, as the temperature increases, so does the viscosity of the mud. This is especially important in hot climates or at higher depths, where increasing the viscosity of drilling mud is crucial for an effective and efficient operation.
- Salinity: Introducing solids, such as salts, into the fluid changes its volumetric properties, making it thicker. The more salt added to the drilling fluid, the denser it becomes. For muddy waters with higher salinity, drilling companies must adjust the amount of oil or gas in the drilling mud. Increasing the concentration of saline content in a water-based drilling fluid can enhance its ability to carry drill cuttings out of wells.
