    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 lines. Freshwater muds are generally lightly treated or untreated muds having a liquid phase of water, containing small concentrations of salt, and having a pH ranging from 8.0 to 10.5. Oil-Base Muds differs from water base muds, Fresh water muds include the following types. Spud Muds These muds are prepared with available water and appropriate concentrations of bentonite and/or premium commercial clays. They are generally untreated chemically, although lime, cement, or caustic soda is occasionally added to increase viscosity and…

    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 API Mud Report. see our Drilling Fluids Books section Sand Content Sand content measurement is the same as for water-base drilling mud except that the mud’s base oil instead of water should be used for dilution. The sand content of oil-base mud is not generally tested. HPHT Filtration The API filtration test result for oil-base drilling…

    Drilling Fluid Definitions and General Functions

      Drilling Fluid Definitions and General Functions Results of research has shown that penetration rate and its response to weight on Drilling 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 horsepower across the bit, it can be concluded that the drilling fluid is as important in determining drilling costs as all other “controllable” variables combined. Considering these factors, an optimum drilling fluid is properly formulated so that the flow rate necessary to clean the hole results in the proper hydraulic horsepower to clean…
