Fracking chemicals have various uses in drilling operations including, prevention of scales in pipe, reduction of friction over base pipe, thickening of water in order to suspend proppants, retention of viscosity of fluid at high temperatures, elimination of bacteria in water, protection of casing from corrosion, and clay stabilization to lock down clays in shale structure.

Fracking chemicals are used in vertical and horizontal drilling operations. The recent shift towards horizontal drilling methods have led to the exponential growth of horizontal wells category in well-type segment. Owing to this scenario, horizontal well was the largest well-type category in 2016 and is expected to maintain its dominance over the next eight years. The horizontal well segment had a market share of 75.6% in 2016.
