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 modelling physical geological structures, the method comprising:
accepting geological data; generating a three-dimensional (3D) transformation 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; accepting an indication to locally change the 3D transformation for a subset of points in a first model of the models, wherein the indication is generated in a computing device using a graphical editing tool represented by a pair of twin 3D volumes, the location, size and shape of which are controllable by a user, wherein a location of a center of one of the twin 3D volumes is chosen by the user to be located on a horizon in the present day model or on a horizontal cross-section in the past depositional model; locally changing the 3D transformation for the subset of points; and displaying a locally altered version of the first model.
