Anisotropy is a phenomenon simultaneously as big as the earth and as small as the atom. In the oilfield, anisotropy of rock properties at a wide range of scales affects nearly all exploration and production disciplines-geophysics, petrophysics, geology and reservoir engineering. Taking advantage of anisotropy begins with understanding its origins in sedimentology. Here is a look at the geologic foundations of anisotropy and a summary of recent findings on the anisotropy of electrical properties of the earth.
