Claim One:
1. A method of assisting in the precise geometric description of a folded subsurface geological structure utilizing a computer and continuous dip sequence data from a dipmeter survey obtained through a wellbore penetrating the geological structure, comprising the steps of: obtaining estimates of geometric parameters from the dipmeter survey describing the geological structure as a stack of surfaces represented in a three dimensional reference by a parametric function together with a continuous description of the borehole course within the three dimensional reference; generating theoretical dip profiles using the estimates along a given borehole course within a plurality of possible mathematical solutions fitting the geological structure; generating critical numbers to allow the selection of a solution model within the plurality of possible solutions; and adjusting the value of the estimates iteratively to generate and display a final dip profile having the highest correlation to the continuous dip sequence from the dipmeter survey.
