Abstract
Abstract Geologists provide models of the Earth's subsurface based on the exposed outcrops and other geological inputs. Providing a reliable model of the Earth's subsurface in terms of structural setting and property variations is the main objective of the investigations by earth scientists. With the advent of sophisticated geophysical techniques, it is possible to integrate the geophysical observations with the geological models to constrain them better and evolve a more realistic model. Several scattered studies (Yu and Li, 2001) have shown that the rock matrix follows fractal behavior from micro- to mega-scale. Geological models can be made using discrete objects, voxels, or surfaces that honor geological and geophysical observations. We present a geophysical modeling technique based on Voronoi tessellations, which honors available geophysical data, viz. horizons from seismic and physical properties derived from well logs, seismic data, and other kinds of geophysical data.
