Drilling fluid types PetroWikiWater-Based FluidsDrill-In FluidsOil-Based FluidsSynthetic-Based Drilling FluidsAll-Oil FluidsPneumatic-Drilling FluidsSpecialty ProductsWater-based fluids (WBFs) are used to drill approximately 80% of all wells. The base fluid may be fresh water, seawater, brine, saturated brine, or a formate brine. The type of fluid selected depends on anticipated well conditions or on the specific interval of the well being drilled. For example, the surface interval typically is drilled with a low-density water- or seawater-based mud that contains few commercial additives. These systems incorporate natural clays in the course of the drillin...
The Application of Polymer Mud System in Drilling
The structure of polymer mud system was formed by the interaction between particles, the bridging role between polymer molecules and particles and the interaction between polymer molecules as well. The structural strength mainly depends on the strength of the bridging role between particles and polymer molecules. Under the condition of high shear stress, the bridging role is destroyed so as to

Most Non-Dispersed Polymer Muds are composed of water with varying quantities of bentonite and polymers. Polymers are added to the system to build viscosity either through flocculation of the solids or by viscosifying the water phase. They are also added to provide filtration control. Some of the more commonly used Non-Dispersed Polymer Muds are:
PHPA mud Schlumberger Oilfield Glossary
A class of water muds that use partially-hydrolyzed polyacrylamide (PHPA) as a functional additive, either to control wellbore shales or to extend bentonite clay in a low-solids mud.As a shale-control mud, PHPA is believed to seal microfractures and coat shale surfaces with a film that retards dispersion and disintegration. KCl is used as a shale inhibitor in most PHPA mud designs.
In geotechnical engineering, drilling fluid, also called drilling mud, is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells.One of the functions of drilling mud is to carry cuttings out of the hole.
