Vanconol® OD Series Oil Displacing Agent
High-Efficiency Salt-Tolerant Ultra-Low Interfacial Tension
1 🎯 Abstract
Vanconol® OD Series is a compound ultra-low interfacial tension oil displacing agent specially developed for high-salinity reservoirs, with natural surfactant complexes as the core component. Under harsh water quality conditions, it can stably achieve an ultra-low oil-water interfacial tension of ≤2.0×10⁻³ mN/m, effectively shielding the interference of Ca²⁺/Mg²⁺, featuring strong adsorption resistance, environmental friendliness, and no APEO. It has a wide range of applicable salinity, breaking through the performance bottleneck of traditional oil displacing agents in high-salinity environments, successfully solving the problem of reduced oil displacement efficiency in high-salinity reservoirs, and significantly enhancing displacement stability. It is suitable for tertiary oil recovery, heavy oil thermal recovery, high-temperature and high-salinity reservoir recovery, and old oilfield recovery scenarios.

5 ❓ Frequently Asked Questions (FAQ)
Q1: Is Vanconol® OD Series suitable for all salinity reservoirs?
A1: This series of products has a wide range of applicable salinity, covering low-salinity (<6,000 mg/L) to high-salinity (30,000-50,000 mg/L) reservoirs. However, corresponding recommended models should be selected for reservoirs with different salinity, and gradient tests are recommended for high-salinity reservoirs to determine the optimal concentration.
Q2: Is pre-dilution necessary before using the product?
A2: Yes, to ensure the use effect, it is recommended to pre-dilute the product to 10% concentration with clean water first, then add it to the oil displacement system according to the dosage.
Q3: Are there any special requirements for product storage?
A3: The storage conditions of room temperature (5~35℃), away from light, cool and dry must be strictly followed to avoid affecting product performance due to improper environment.
