Polymers & Surfactants for Enhanced Oil Recovery (EOR)

Challenge:

Mature onshore oil fields often experience declining oil production rates as natural reservoir pressure decreases. The challenge is to boost oil recovery from these mature fields without compromising efficiency or increasing operational costs. Additionally, oil recovery solutions must be compatible with challenging reservoir conditions, such as high temperatures and high salinity.

Solution:

Vanchor Supply Chain Management (Hebei) Co., Ltd. provided a tailored solution using Polymers and Surfactants specifically designed for Enhanced Oil Recovery (EOR). These advanced chemicals were used to improve the oil recovery process by altering the flow characteristics of the reservoir fluids, helping to displace more oil towards the production wells.

The polymers helped increase the viscosity of the injected fluids, while the surfactants reduced the interfacial tension between oil and water, promoting better oil mobilization. The solution was carefully selected to be compatible with high-temperature, high-salinity reservoir conditions, ensuring that it would perform effectively even under harsh environmental conditions typically found in mature oil fields.

Results:

• 18% increase in oil recovery rate: The use of polymers and surfactants boosted the oil recovery rate by 18% in the client’s mature onshore oil fields, significantly enhancing production.
• Compatibility with challenging conditions: The solution was fully compatible with high-temperature, high-salinity reservoirs, maintaining performance in harsh conditions.

Conclusion:

Vanchor Supply Chain Management (Hebei) Co., Ltd. successfully applied polymers and surfactants for Enhanced Oil Recovery, achieving significant improvements in oil recovery rates. By addressing the specific challenges of high-temperature, high-salinity reservoirs, Vanchor’s solution enhanced the production of mature onshore oil fields, showcasing its commitment to providing effective and reliable chemical solutions in the oil and gas industry.
