From Australian Order to Core Additive Strength: How Glutaraldehyde + THPS Safeguard the Lifeline of Oil & Gas Extraction

Recently, a container loaded with Glutaraldehyde and THPS supplied by SINOBIO was successfully shipped to Australia and delivered to a well-known local oil and gas industry customer. Behind this seemingly routine delivery lies the rigid demand for efficient and safe chemical additives in the oil and gas extraction sector—and the combination of glutaraldehyde and THPS is precisely the "invisible guardian" that supports the stable operation of the entire oil and gas extraction process.

Practitioners with extensive experience in the oil and gas extraction industry are well aware that the environment of underground oil and gas reservoirs is far more complex than imagined. In high-temperature and high-pressure closed spaces, various microorganisms multiply rapidly, leading to recurrent issues such as pipeline scaling and formation blockage. These problems can slightly reduce extraction efficiency, or in severe cases, cause equipment scrapping and reservoir damage, resulting in millions of dollars in economic losses. The customized glutaraldehyde + THPS composite solution for the Australian customer is precisely a high-efficiency solution tailored to the special working conditions of high salinity and high microbial activity in local offshore oil and gas fields.

As a mature broad-spectrum bactericide applied in the oil and gas industry, the bactericidal performance of glutaraldehyde has long been verified by the global market. Its unique chemical structure can quickly penetrate microbial cell membranes and react with protein amino groups, completely destroying the metabolic systems of bacteria, fungi and algae—with particularly significant effects on sulfate-reducing bacteria (SRB) that cause pipeline corrosion. Compared with ordinary bactericides, glutaraldehyde has stronger stability in high-salinity wastewater and can maintain a bactericidal efficiency of over 90% in high-temperature environments below 80°C. A single dosage can achieve a continuous bacteriostatic effect for up to 72 hours, significantly reducing the labor cost of frequent dosing on offshore platforms.

The addition of THPS (Tetrakis Hydroxymethyl Phosphonium Sulfate) enables this solution to achieve a synergistic effect of "1+1>2". As an environmentally friendly corrosion and bactericide inhibitor, THPS can not only cooperate with glutaraldehyde to expand the bactericidal spectrum and precisely target certain stubborn strains resistant to glutaraldehyde, but also form a dense protective film on the surface of metal pipelines, effectively inhibiting pipeline perforation caused by microbial corrosion and electrochemical corrosion. The Australian customer was previously troubled by the problems of high sulfur content in the produced fluid of offshore oil wells and excessive pipeline corrosion rate. After trying multiple solutions without radical results, on-site monitoring data showed that after adopting the glutaraldehyde + THPS composite system, the pipeline corrosion rate decreased by 60%, and the content of sulfate-reducing bacteria dropped to below 10² CFU/mL, fully meeting the industry first-level standard.

In addition to their core role in bactericidal and corrosion inhibition, the combination of glutaraldehyde and THPS also demonstrates irreplaceable value in multiple key links of oil and gas extraction. In drilling fluid treatment, the combined use of the two can effectively inhibit the mildew of drilling fluid, prevent abnormal viscosity changes, and ensure the smooth progress of drilling operations; in the oil and gas gathering and transportation stage, the composite system can reduce the emulsification degree of produced fluid, reduce scaling and blockage of gathering and transportation pipelines, and improve oil-gas separation efficiency. More notably, as an environmentally friendly additive, THPS degrades into harmless phosphate and formaldehyde, which fully complies with Australia's strict environmental emission requirements—this is also one of the key factors for the successful conclusion of this cooperation.

From onshore oil fields in Southeast Asia to offshore platforms in Australia, and from conventional oil and gas extraction to shale gas development, the combined solution of glutaraldehyde and THPS has been applied in dozens of oil and gas projects around the world. The successful delivery to the Australian customer this time is not only a recognition of product quality, but also a testament to our technical strength in deeply cultivating the oil and gas additive field. As oil and gas extraction moves towards a more complex, efficient and environmentally friendly direction, we will continue to optimize product formulas, customize solutions more suitable for working conditions, and safeguard the lifeline of global oil and gas extraction with core additives.
