Abstract
The invention relates to drilling fluids used in methods for drilling wells into subterranean formations containing oil, gas or other minerals for the purpose of extraction and production of said minerals and the use of starch in such fluids. The invention provides a method for drilling such a well using a drilling fluid comprising a high-amylose starch or starch-blend.
