Systems and methods for coordinated editing of seismic data in dual model

摘要

A system and method may model physical geological structures. Seismic and geologic data may be accepted. A three-dimensional (3D) transformation may be generated between a 3D present day model having points representing present locations of the physical geological structures and a 3D past depositional model having points representing locations where the physical geological structures were originally deposited. An indication may be accepted to locally change the 3D transformation for a subset of sampling points in a first model of the models. The 3D transformation may be locally changed to fit the updated subset of sampling points. A locally altered or updated version of the first model and, e.g., second model, may be displayed where local changes to the first model are defined by the locally changed 3D transformation. The transformation may also be used to extract geobodies in the past depositional model.

1. A method for incrementally updating a model of physical geological structures, the method comprising:
modeling an initial set of horizons in a past depositional space, wherein the past depositional space represents locations where physical geological structures are computed to have been originally deposited in the past, wherein each horizon is computed to have been originally deposited at a substantially constant geological time in the past; receiving a selection of one or more seed points in the past depositional space that have values deviating from those along the same horizon; transforming the selected seed points, using a transformation, from the past depositional space to corresponding seed points in a present day geological space, wherein the present day geological space represents the present day locations of physical geological structures; automatically extracting a set of new seed points from the transformed seed points to generate a new horizon in the present day geological space; locally changing a transformation from the present day geological space to the past depositional space for the set of new seed points; and displaying the model comprising the initial set of reference horizons and the new horizon.
