MODELING GEOLOGIC SURFACES USING UNILATERAL NON-NODE CONSTRAINTS FROM NEIGHBORING SURFACES IN THE STRATIGRAPHIC SEQUENCE.

摘要

Systems and methods for modeling th ree-dimensional ("3D") geologic su rfaces, which represent a constraining surface and a constrained su rface, in a stratigraphic conforming relationship that do not intersect or overlap. The method bui lds 3D su rface models that represent constraining and constrained surfaces in a stratigraphically conforming relationship that do not intersect each other or overlap. I n an embodiment, 3D data points from the constrained su rface may be used as maxima or minima while building the constraining surface. I n this manner the constraining surface will not have any 3D data points from the constrained surface on both sides of it. I n another embodiment, both the constraining and constrained su rfaces are built simultaneously so that they can be used as mutual minima or maxima and prevent their intersection or overlap.
