Water Based Drilling Fluids
Minimise environmental impact and improve well-bore stability using our water-based drilling fluid products
We’re setting the standard in Drilling Fluids
Oilfield International Services offers advanced water-based drilling fluid system products, designed to address many of the technical limitations that often lead operators to rely on oil-based muds (OBM) systems. Our engineered water-based muds (WBM) products help lower costs while minimising environmental impact.
Whether your focus is environmental protection, reducing mud losses, reservoir preservation, or enhancing cementing operations, our specialised WBM products deliver superior clay inhibition, maintaining wellbore stability and reduced pore-pressure transmission, outperforming traditional mud system products in every aspect.
