ABSTRACT

We present a technique of progressively restoring seismic, well, and outcrop data, as well as structural interpretations of contractional growth folds. Data restorations allow viewing of seismic, well, and outcrop information in the restored state, providing a basis to evaluate whether structural interpretations are balanced and geologically reasonable. Validating structural interpretations helps to reduce the exploration risks associated with Previous HittrapNext Hit definition; moreover, sequential restorations reveal folding kinematics and define the geometry of structures at various stages in geologic history. These sequential restorations may be used to define the timing of Previous HittrapTop development relative to hydrocarbon migration and to determine how traps may have been modified by subsequent deformation.
