Bentonite continues to rank second in quantity only to barite as a mud additive, as shown in Fig. 11-2.14 In spite of the partial replacement of bentonite by polymers in some muds, about 1,160,000 short tons (1,050,000 tonnes) of swelling-type bentonite, with a well-site cost of roughly $120,000,000 (check also oil well drilling well cost per foot), was used in 1978.

Bentonite, a versatile clay mineral, holds immense significance across various industries due to its unique properties and applications. Bentonite is typically mined from natural deposits and undergoes a series of processing steps to enhance its properties. This includes drying, grinding, and milling to achieve the desired particle size and purity.
