Drilling Bentonite
Offer type: salePublished: 25.07.2012
OREWORLDTM drilling bentonite is produced according to the Chinese National Standards: GB/T5005-2001 (eqv ISO 13500: 1998). This material is as a mud constituent for oil- and water- well drilling. Its role is mainly to seal the borehole walls, to remove drill cuttings and to lubricate the cutting head. The special higher mud yield results in using less quantity of Bentonite for the same standard mud. This results in lesser requirement of Bentonite.
