"Sulphonated Asphalt Soltex
Weifang Longstar Chemical Inc., based in Shandong, China, supplies Sulphonated Asphalt Soltex FT-1 (CAS 68201-32-1), a multifunctional organic drilling fluid treatment agent. The product is a flowing black powder with a sodium sulphonate content of 10% minimum and water solubility of 80% minimum. Its strong hydration effect, driven by the sulfonic acid group, allows it to adsorb onto shale interfaces, preventing hydration and dispersion of shale particles. The water-insoluble fraction fills pore throats and fractures, providing a plugging action while covering the shale to improve mud cake quality.
This sulphonated asphalt serves multiple roles in drilling operations: it lubricates the drill string to reduce torque and drag, lowers high-temperature high-pressure (HTHP) filtration rates, and helps form a thin, tough mud cake to stabilise the wellbore. Recommended dosage ranges from 1% to 6% of the mud system, and it can be combined with other treatment agents. Current pricing is listed at USD 715.00 per metric tonne FOB Qingdao, China, with a minimum order of 1 MT packed in 25 kg paper bags. Buyers should confirm lead times and any required documentation directly with Weifang Longstar Chemical Inc.
