Drilling fluids
A fluid for every ground
Polymer drilling fluids and additives from ProAction Fluids, from sticky clay to sand, gravel and rock. Six products that work together — start from one base fluid and add what the ground calls for.
Synthetic polymer HDD fluid
TurboBore
A one-product drilling fluid: no recipe and no other additives needed. Best suited to sand and rocky soil.
View drilling fluids→
Soil stabiliser and viscosifier
ProDrill
Multi-polymer blend that builds viscosity and binds clay and other low-density solids, so the cuttings leave the bore cleanly. The base of the ProBore series.
View drilling fluids→
Water-based, hydrocarbon-free
ProDrill ECO
The water-based version of ProDrill, with no oil or hydrocarbons — for jobs where oil-based carrier fluids are not allowed.
View drilling fluids→
Drilling detergent and water conditioner
ProDyne
Non-foaming detergent that softens hard water and keeps sticky clay from clinging to the bit, the rods and the tooling.
View drilling fluids→
Clay control additive
ClayLock
Clay inhibitor that stops reactive clays from swelling and grabbing the pipe and the tooling.
View drilling fluids→
Liquid viscosifier, lubricant and filtration control
GeoSweep LQ
Liquid multi-polymer blend for dense, permeable ground from sand to rock: disperses quickly, carries coarse cuttings out and seals the bore wall.
