Abstract
A method for structure modeling of a formation penetrated by multiple wells includes obtaining borehole dips from borehole measurements; filtering the borehole dips based on a dip sequence analysis; computing structural dips based on the filtered dips; computing structural delineation by using the structural dips; projecting the structural dips to horizon point sets based on the structural delineation; and generating stratigraphic surfaces by mapping the projected horizon point sets. A system for structure modeling of a formation penetrated by multiple wells includes a processor and a memory that store a program having instructions for: obtaining borehole dips from borehole measurements; filtering the borehole dips based on a dip sequence analysis; computing structural dips based on the filtered dips; computing structural delineation by using the structural dips; projecting the structural dips to horizon point sets based on the structural delineation; and generating stratigraphic surfaces by mapping the projected horizon point sets.
