An Iranian oilfield service company encountered difficulties with borehole instability and poor cuttings carrying during deep drilling operations in high-temperature reservoirs. They turned to Qinghong’s 881-A Organic Bentonite Rheological Additive, specifically designed for diesel-based drilling mud systems. The product’s excellent viscosity control and high-temperature stability (up to 180℃) improved mud suspension capacity, reducing fluid loss by 30% and preventing borehole collapse. Our customized formulation adapted to the region’s geological conditions, cutting drilling time by 18% and lowering operational costs significantly. Backed by our 21 years of export experience, we ensured compliance with local import regulations and provided prompt technical support, helping the client complete their drilling projects safely and efficiently. This successful cooperation has made Qinghong their preferred supplier for rheological additives in the Middle East market.
