Sulfonated asphalt
Drilling fluids agent Consatone ®

Shale stabilizer, fluid loss reducing agent

Sulfonated asphalt is a clay / shale inhibitor which is designed specifically to solve wellbore instability problems. It increases wellbore stability, plugs pores and microfractures, prevents weakening of the structure, softening and sloughing of the rock.

Sulfonated asphalt helps to form a thin and dense filter cake and fine particles effectively clog shale microcracks and pores. When treated with sulfonated asphalt drilling fluid filtrate penetrates into the structure of clay rock, the degree of hydration, swelling and heaving is significantly reduced due to inhibition by substances in the drilling fluid filtrate.

It is resistant to major drilling mud contaminants, operates over a wide pH range and resistant to temperatures up to 204°C.
