DRAWING GRAPHICAL OBJECTS IN A 3D SUBSURFACE ENVIRONMENT

摘要

A system and method for drawing in a three-dimensional space. The drawings may include dots, line segments, arrows, polylines (open and closed), polygons, surfaces and 3D volumes. The method may include receiving user input that specifies a drawing in a displayed window and mapping the drawing into the 3D space. The mapping process may involve mapping the drawing onto a surface of an existing graphical object in the 3D space, or, mapping the drawing onto a user-specified plane in the 3D space. The drawing may represent a user's interpretation of a geological feature present on the graphical object surface. The graphical object may represent an object of significance in hydrocarbon exploration and production, e.g., an interpreted section or horizon in the earth's subsurface.
