Observations of water-clay reactions in water-sensitive sandstone and mudrocks using an environmental scanning electron microscope. J.M. Huggett and P.J.R. Uwins. J. Petrol. Sci. Engng., February 1994, 10(3), 211--222.

The experimental in situ wetting and drying of water-sensitive mudrocks in an environmental scanning electron microscope (ESEM) is described. The study reported demonstrates that the ESEM is an extremely effective tool for the study of fluid-clay interaction in rock. Not only is it possible to examine uncoated material which may as a consequence be treated with a variety of fluids, but the results may be observed directly and at high magnification. 8 refs.
