Drilling fluids are defined as the fluid used to lubricate the drill string, line the well bore, flush drill cuttings to the surface and create enough hydrostatic weight to prevent blowouts. Composition of a drilling fluid can be catagorized into
- Water-based
- Brine-based
- Oil-based
- Synthetic-based
The mud cools the rapidly rotating bit; lubricates the drill pipe as it turns in the wellbore; carries drill cuttings to the surface; and serves as a plaster to prevent the wall of the borehole from crumbling or collapsing. It also provides the weight or hydrostatic head to prevent extraneous fluids from entering the wellbore and to control down hole pressures that may be encountered.
Chemteck drilling fluid additives include:
- Corrosion Inhibitors
- Scale Inhibitors
- Sulfide Scavengers
- Polymers & Viscosifiers
- Foaming Agents
- Defoamers
- Clay/Shale Stabilizers
- EPA Registered Biocides
- Environmentally Safe Lubricants
- Flocculants
- Mud Thinners & Dispersants
- Lost Circulation
- Weighting Material
- Fluid Loss Reducer
- Alkalinity Control
