Abstract: Method and system for 3-D imaging of subterranean geologic structures based on seismic data interpretations involves correcting mis-ties that arise as a result of orthogonal polylines failing to intersect due to inconsistencies in seismic interpretations. In some embodiments, the mis-ties may be corrected by adding a data point from one polyline at or near the mis-tie to the other polyline, and vice versa for the other polyline. The two data points are then adjusted so they coincide or merge. The merged data point is then used as intersection points for the polylines and associated with one another such that a change made to one intersection point is automatically made to the other intersection point. In some embodiments, one or more neighboring data points on each polyline are adjusted to smooth out the polyline at the point of the corrected mis-tie.

Abstract: Embodiments of the invention provide a method for classifying seismic attributes, including generating data points by cross plotting seismic attributes from a first data volume and a second data volume, encompassing at least one of the generated data points within a polygon, generating a reference line, determining an interpolation direction relative to the reference line, and assigning an attribute value to the at least one generated data point encompassed within the polygon wherein the assigned attribute value is interpolated based on the combination of its position to the reference line along the interpolation direction and the shape of the polygon.

Abstract: Method and system for 3-D imaging of subterranean geologic structures based on seismic data interpretations involves converting multi-Z polylines into single-Z line segments. The single-Z line segments have slopes that are either positive or negative and do not change signs. As a result, no point along the line segment has more than one value in Z. The single-Z line segments may then be grouped or assembled into lattices that may then be used to form single-z horizons. Such a method and system arrangement provide a far more efficient and less processing intensive way to render 3-D images of the geologic structures compared to existing solutions.
