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. |
