Emulsions, The Silent Foe of Oilfield Formations

Emulsions are like tiny troublemakers that can form when crude oil and aqueous acid mingle. They consist of oil droplets suspended in water. While that might sound harmless, in the world of oil and gas, it's a recipe for disaster. Emulsions can block the pores in the formation, creating formation damage. And they're not easy to get rid of because some compounds in crude oil stabilize these emulsions.

Formation damage is the enemy of productivity. Emulsions can stubbornly remain stable for hours underground, turning the mixture into a thick, gooey mess. This increased viscosity makes it challenging for the crude oil to flow, resulting in higher pumping costs and potential corrosion risks. Moreover, valuable oil reserves can be wasted before production even begins.

DosSurf™ Non-Emulsifier

Non Ionic Surfactant Emulsion Modifier

DOSAS, DosSurf™ Solutions provide emulsion-prevention in aqueous solutions, of water and oil emulsions in a high brine, harsh environments as high temperature and high-pressure or highly acidic of up to 30wt% acid environments, having applicability within a wide range of crude oils.

  • Medium Heavy Crude

    Non-Emulsifier for High API Gravity Crude


    When added to brines and acidic solutions, it acts as a protective barrier between oil and fluid, preventing emulsion and preserving reservoir oil while maintaining fluid properties.

  • Asphaltenic Crude

    Non-Emulsifier for Low API Gravity Crude


    Some emulsions can be very stable, particularly the acid emulsions, due to strong and complex interactions between the aromatic and polyaromatic hydrocarbons with oxygenated species in the acidic medium and in the presence of various metal salts, resins and asphaltenes.

Unveiling Our
Non-Emulsifier Surfactants

At DOSAS, we strive to develop non-emulsifiers like DosSurf™ that embody the optimal balance of performance, reliability, and compatibility for oilfield stimulation. Each product undergoes comprehensive laboratory testing to validate its effectiveness and adaptability to a broad spectrum of stimulation chemicals. This rigorous approach reflects DOSAS commitment to delivering industry-leading solutions that are purpose-built to excel in the field. DOSAS Non-Emulsifying Agents are designed to meet a range of criteria to be safely applied without harming the systems:


• Emulsion Tendency Tests,

• High-Salinity and Density Brine Compatibility,
• Interfacial Tension (IFT) Measurements,

• Low Foaming Tendency Tests.

Non-Emulsifier Evaluation Process

To address salt saturation and divalent cation challenges, our non-emulsifiers ensure full solubility in high-density brines and maximize crude-brine interface attraction. Rigorous testing on crude samples evaluates solubility, emulsion prevention, and compatibility with maximum brine density. Contact DOSAS for reliable, high-performance non-emulsifier solutions.
