Comprehensive OBM &
Non-Aqueous Drilling Fluid Solutions

Engineered Drilling Fluids for Complex Drilling Challenges

Comprehensive OBM / Non-Aqueous Drilling Fluid Solutions

At Oilfield International Services, our non-aqueous drilling fluid products are engineered to meet the full spectrum of operational demands — from conventional mineral oil-based fluids to advanced synthetic-based formulations. These invert emulsion systems are designed to perform reliably under a wide range of pressures, temperatures, and complex wellbore formations.

By dispersing water in a continuous oil phase, our non-aqueous products offer exceptional stability in the presence of high electrolyte concentrations, soluble gases, and elevated temperatures — making them ideal for technically challenging wells.

Pushing Toward More Sustainable Alternatives

In parallel, we’re committed to evolving our portfolio of water-based drilling fluid products. Our specialists work closely with clients to identify opportunities where these more environmentally responsible systems can be used without compromising performance — reducing environmental impact while maintaining operational efficiency.

OIS Coding Fluid System Function OIS Brand Name Chemical Product Description
OIS OBM 001 OBM / NON-AQUEOUS Alkalinity –Emulsion Stability Lime Hydrated Lime is used in Oil Based fluid systems as a source of calcium and alkalinity. Excess Lime provides an alkalinity buffer in the fluid system.
OIS OBM 002 OBM / NON-AQUEOUS Viscosifier VEN-VIS CL VEN-VIS CL is an amine treated bentonite, specifically functioning as a viscosifier for OBM fluid systems.
OIS OBM 003 OBM / NON-AQUEOUS Viscosifier VEN-MOD LER VEN-MOD LE is a rheology modifier, designed to provide high viscosity at low shear rates, improving formation cuttings carrying capacity and weighting material suspension characteristics.
OIS OBM 004 OBM / NON-AQUEOUS Viscosifier VEN-MOD FLT VEN-MOD FL specifically targets flat rheologies, providing properties such as high shear thinning, temperature stability and viscosity control, leading to excellent hole cleaning.
OIS OBM 005 OBM / NON-AQUEOUS Thinner VEN-THIN VEN-THIN is an additive used in an OBM fluid system to reduce the viscosity and gel strength thickening properties of OBM, without the requirement for dilution or changing OWR.
OIS OBM 006 OBM / NON-AQUEOUS Emulsifier VEN-MUL P VEN-MUL P is a multi-purpose primary emulsifier product, with a liquid blend of selected emulsifiers, wetting agents and gelling agents.
OIS OBM 007 OBM / NON-AQUEOUS Emulsifier VEN-MUL S VEN-MUL S is a multi-functional secondary emulsifier product, with wetting agent and filtration control properties.
OIS OBM 008 OBM / NON-AQUEOUS Emulsifier VEN-MUL DR VEN-MUL DR is a multi-purpose and multi-functional one drum single component emulsifier.
OIS OBM 009 OBM / NON-AQUEOUS Emulsifier VEN-MUL HT VEN-MUL HT is a multi-purpose and multi-functional one drum high temperature single component emulsifier.
OIS OBM 010 OBM / NON-AQUEOUS Fluid Loss Control VEN-TROL VEN-TROL is a fluid loss control product, which also provides thermal and emulsion stability.
OIS OBM 011 OBM / NON-AQUEOUS Wetting Agent VEN-WET VEN-WET is a primary wetting agent and secondary emulsifier in OBM fluid systems.
OIS OBM 012 OBM / NON-AQUEOUS Pipe Freeing Agent VEN-SOL VEN-SOL is a mutual solvent which has a wide range of applications, increases both the solubility of hydrocarbons and wettability in OBM fluid systems. Can be used in a stuck pipe context when spotted around the area of concern.
