The use of drilling fluid additives can have a huge impact on drilling performance in geotechnical drilling. Drillers routinely encounter abrasive or fragmented ground, flowing sands and dry hole conditions. In the past bentonite was often the product drillers reached for but bentonite is very abrasive and can wear down drilling equipment prematurely. Today, new drilling additives have been developed that resolve specific drilling problems. Here are 5 products that you should be aware of.
