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.

Product List

OIS Coding Fluid System Function OIS Brand Name Chemical Product Description (Write Up)
OIS WBM 001 WBM pH Control CAUSTIC SODA Caustic Soda (Sodium Hydroxide) flakes are predominantly used in water based drilling fluids, playing a critical role of manipulating the pH levels and maintaining wellbore stability.
OIS WBM 002 WBM pH Control SODA ASH Soda Ash is another pH control product which is predominantly used in water based drilling fluids, removes calcium, softening the water and raising the pH, the combination of treating out hardness and raising pH, allows for maximum hydration of products.
OIS WBM 003 WBM pH Control SODIUM BICARBONATE Sodium Bicarbonate is used to treat soluble calcium in water based drilling fluids as a source of bicarbonate ions, which precipitate calcium and reduce pH. Sodium Bicarbonate is most commonly used to treat a cement contamination.
OIS WBM 004 WBM pH Control CITRIC ACID Citric Acid is used to reduce pH in water based drilling fluids, by precipitating soluble calcium and sequester iron and other metal poly-cations.
OIS WBM 005 WBM Viscosifier VEN–XAN VEN–XAN, XCD Polymer is primarily used as a viscosifier in drilling and completion fluids, it can be used as a viscosity modifier for both fresh water and salt saturated water based fluid systems.
OIS WBM 006 WBM Viscosifier VEN–GUM 3500 VEN–GUM (3500 CPS) is commonly used as a viscosifier in water based drilling fluids, this is fast hydrating and eco friendly viscosifier derived from purified Guar Gum.
OIS WBM 007 WBM Viscosifier VEN–GUM 5000 VEN–GUM (5000 CPS) is commonly used as a viscosifier in water based drilling fluids, this is fast hydrating and eco friendly viscosifier derived from purified Guar Gum.
OIS WBM 008 WBM Filtration Control / Viscosifier VEN–PAC HV (API–13A) VEN–PAC HV (API–13A) – Polyanionic Cellulose High Viscosity is used in water based drilling fluids for a variety of applications, such as filtration control, viscosity and shale inhibition.
OIS WBM 009 WBM Viscosifier / Filtration Control VEN–PAC R (65% or 98%) VEN–PAC R (65% or 98%) Polyanionic Cellulose Regular is used in water based drilling fluids for a variety of applications, such as filtration control, viscosity and shale inhibition.
OIS WBM 010 WBM Filtration Control / Viscosifier VEN–PAC LV (API–13A) VEN–PAC LV (API–13A) Polyanionic Cellulose Low Viscosity is used in water based drilling fluids for a variety of applications, such as filtration control, viscosity and shale inhibition.

Oilfield International Services possesses extensive experience in drilling and completion fluids, having successfully executed numerous projects for major oil and gas operators across the globe.
