The oil and gas industry continually seeks innovative solutions to maximize resource extraction, particularly in enhanced oil recovery (EOR) operations. Sodium Alpha Olefin Sulfonate (AOS), a versatile anionic surfactant with excellent interfacial properties, is gaining attention for its potential to improve oil recovery efficiency. As a leading chemical supplier in China, we offer AOS that can support advanced EOR strategies.

AOS, identified by CAS 68439-57-6 and available in high purity grades like 92%, exhibits remarkable surfactant characteristics that are highly relevant to EOR. Its primary function in this context is to reduce the interfacial tension between oil and water, thereby mobilizing trapped oil that cannot be recovered by conventional methods. This is often achieved through techniques like surfactant flooding.

The effectiveness of AOS in EOR is attributed to several factors. Firstly, it possesses excellent wetting and spreading abilities, which helps to alter the wettability of reservoir rock, making it more oil-wet or water-wet as needed to promote oil displacement. Secondly, its good foaming properties can be advantageous in certain EOR methods, such as foam flooding, which can improve sweep efficiency and reduce gas mobility.

Furthermore, AOS demonstrates good stability under various reservoir conditions, including salinity and temperature, which are critical for the long-term performance of injected surfactants. Its biodegradability also presents a more environmentally conscious option for large-scale operations compared to some traditional petrochemical-based surfactants.

For oilfield service companies and EOR specialists looking to procure advanced chemical solutions, purchasing AOS from a reliable Chinese manufacturer offers a strategic advantage. We provide high-quality AOS with consistent properties, ensuring predictable performance in complex reservoir environments. Understanding the specific requirements of your EOR project is key to optimizing AOS usage.

The application of AOS in EOR is an area of ongoing research and development, focusing on optimizing formulations and injection strategies to maximize oil recovery. Its ability to form stable microemulsions and reduce residual oil saturation makes it a promising candidate for cost-effective EOR applications.

In conclusion, Sodium Alpha Olefin Sulfonate (AOS) is a potent surfactant with significant potential to enhance oil recovery processes. Its ability to reduce interfacial tension, its favorable wetting properties, and its stability make it a valuable tool for the oil and gas industry.
