Abstract
MUD-FLUID is now an important factor in oilfield development, but although it has actually been in use for more than sixty years, comparatively little technical literature is available on the subject. P. Evans and A. Reid, being sensible of this position, and particularly of the essential part now played by mud-fluid in rotary drilling, have compiled a paper (Trans. Min. and Geol.4 Inst. India, 32, December 1936) which has for its theme the investigation of the properties of mud-fluid, its manufacture and testing.
