Unitedhb Group (www.unitedhb.com)  produce high quality of sulphonated asphalt for oil drilling

Sulphonated Asphalt is widely applied as versatile mud conditioner of drilling fluid, it .has a strong hydration capability for it contains sulfonic acid groups. Sulphonated Asphalt can prevent collapse by stopping the hydration and disperse of shale particles when adsorbed on shale interface, at same time, its insoluble part can plug by filling the pore throat and cracks, and cover the shale interface, improve the mud quality. Sulphonated asphalt also can lubricate and reduce the filtration loss of high temperature and pressure.

It works to:

1, plug, anti-collapse, reduce drag, inhibit.

2, Improve lubricity, increase the lifetime of drill bit, prevent and release the sticking drill, and reduce  torque and drag of the drilling string.

3,Form thin and tough mud cake to strengthen well side to control high temperature water loss;

4,Control the shear strength of mud

5, Seals small fractures in stressed shale formulation.

6, Inhibits swelling clay and water wetting of shale;

7, Improves Filter cake Quality and helps seal micro fractures

8, well compatible with all water based mud systems.
