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

A method for simultaneously editing models representing the same physical geological structures, the method comprising:

• accepting geological data;
• displaying a first model and a second model, wherein one of the models represents present locations of the physical geological structures and the other one of the models represents locations where the physical geological structures were originally deposited in the past, wherein the first and second models are related by a three-dimensional (3D) transformation;
• accepting graphical user input editing property values assigned to a first subset of points of the first model, wherein the graphical user input 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 location model or on a horizontal cross-section in the past depositional model;
• automatically assigning the edited property values to a second subset of points of the second model, wherein the second subset of points is the image of the first subset of points as defined by the 3D transformation between the first and second models;
• and
• displaying the second subset of points in the second model with the automatically assigned property values.

A system comprising:

• a memory to store 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;
• a processor to:
• accept 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 the processor 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;
• and
• to locally change the 3D transformation for the subset of points;
• and
• a display to display a locally altered version of the first model.
