Taking non constant anisotropy into account with D.S.I.

 abstract = { Interpolating physical properties in the sub-surface is a recurrent problem in geology. In sedimentary geology, due to paleo-environment conditions which prevailed at deposition time, there are often strong anisotropies in the geographical variations of these properties. For example, the distribution of sediments and thus their physical properties in a deltaic environment or in a channel environment depend on the orientation of the streams at deposition time. Another example is the distribution of facies more or less parallel to the shoreline. Whatever its origin, anisotropies must be taken into account by the interpolation method used to estimate the properties in the subsurface. In this article we present a new method based on a new type of DSI constraint which has the advantage of being mathematically well established in the case where the direction of anisotropy varies in the studied domain. },
