It stabilizers the shale formation, inhibits dispersion of drilled solids, improves lubricity and reduces torque & drag of the drilling string. It controls HTHP fluid loss by producing a thin strong compressible wall cake.

When encountering shale during drilling operations, water in the drilling fluid may interact with the clay materials within the formation, causing the shale to swell. This can lead to instability in the wellbore, and dispersion of shale into the drilling fluid (sloughing), eventually leading to hole washout.

Depending on specific needs, we have developed a range of shale inhibitors with differing molecular weights, ionicity, and product forms to cater to different conditions and fluid systems. The products range from hydration inhibitors to multifunctional polymers which give additional viscosity and carrying capacity.

Alternatively where such viscosity is not desired i.e., in low solids non-dispersed muds or in mud pre-mix concentrates, this effect is minimized but shale inhibition is maintained. This is achieved by controlling polymer molecular weight during the manufacturing process.
