Paper Abstract
3 pages in length. Asbestos – with all its implication for disease to the human body if inhaled – is still utilized as a drilling fluid viscosifier (thickening agent), primarily because of its inherent ability to keep down costs. That asbestos is not nearly as advantageous as clays, which are the predominant choice, speaks to the limited usage this fibrous silicate material – such as a binding agent - can contribute to the drilling process; however, when asbestos is incorporated into the drilling fluid, the cost-saving components are derived from a combination of ready availability and the inexpensive nature of soluble silicates as bonding agents. Bibliography lists 10 sources.
