Water-Base Muds

    Drilling Muds A water-base drilling fluid is one that has water as its continuous or liquid phase. The types of drilling fluids are briefly described in the following sections. Freshwater muds are generally lightly treated or untreated muds having a liquid phase of water, containing small concentrations of salt, and having a pH […]

Oil-Base and Synthetic-Base Muds

Drilling Mud Tests The field tests for rheology, mud density, and gel strength are accomplished in the same manner as outlined for water-based drilling mud. The main difference is that rheology is tested at a specific temperature, usually 120◦F or 150◦F. Because oils tend to thin with temperature, heating fluid is required and should be reported on the […]

Drilling Fluids

Drilling Fluid Definitions and General Functions Results of research has shown that penetration rate and its response to weight on bit and rotary speed is highly dependent on the hydraulic horsepower reaching the formation at the bit. Because the drilling fluid flow rate sets the system pressure losses and these pressure losses set the hydraulic […]
