Abstract

Current developments in 3-D Earth Modeling are having a significant impact on the practise of reservoir model construction, seismis inversion, and velocity analysis. From seimic surveys, acquired and interpreted by geophysicists, geological objetcs are generated. These objects (horizons and faults) are edited and modified as necessary. Once the set of horizons and faults-the structural framework- has been validated, it is used to built a reservoir or velocity model. One difficulty of model building lies in finding the intersections between geological objects. Those interstions have to be clearly defined and controlled by structural information. We present in this article a new work-flow for building a sealed topologically consistent structural framework.
