CT BENTO S11 – BENTONITE API 13A SECTION 11 / OCMA GRADE

DESCRIPTION

CT BENTO S11 is a treated premium grade Bentonite confirms to API 13A   Section 11 / OCMA Specification. It is a viscosifier and gelling   agent. It provides viscosity and good gelling characteristics in most   water-based drilling fluids. It also   reduces fluid loss and filtrate seepage into the formation.

ADVANTAGES

Provides   suspension properties for drilling fluids weighted with barite or hematite

Enhances   hole cleaning capacity of drilling fluids

Environmentally   safe

Disperses readily with adequate   shear in fresh water and fresh water drilling fluids

APPLICATIONS

· Provides viscosity in   anionic water-based drilling fluids.

· Reduces fluid loss and   water seepage into permeable formations.

· Forms a thin filter   cake with low permeability.

· Enhances hole   stability in loosely consolidated formations
