Adaptive wavefront reconstruction

A computer-readable medium having stored thereon computer-executable instructions which, when executed by a computer, cause the computer to:

• perform a ray tracing on a subsurface to generate a plurality of rays;
• reconstruct a first seismic wavefront by triangulating a first plurality of control points that correspond to the plurality of rays, each control point representing an end point of a ray at the first seismic wavefront;
• propagate the plurality of rays to a second seismic wavefront having a hole associated with a missing ray at the second seismic wavefront;
• determine a second plurality of control points defining the hole;
• generate a circle having a plurality of points disposed thereon, wherein the plurality of points correspond to the second plurality of control points;
• triangulate the plurality of points on the circle to form a plurality of triangles within the circle;
• and
• map the plurality of triangles to the hole defined by the second plurality of control points.

A computer system, comprising:

• a processor;
• and
• a memory comprising program instructions executable by the processor to:
• perform a ray tracing on a subsurface to generate a plurality of rays;
• reconstruct a first seismic wavefront by triangulating a first plurality of control points that correspond to the plurality of rays, each control point representing an end point of a ray at the first seismic wavefront;
• propagate the plurality of rays to a second seismic wavefront having a hole associated with a missing ray at the second seismic wavefront;
• determine a second plurality of control points defining the hole;
• generate a circle having a plurality of points disposed along the circle at equal distance, wherein the plurality of points correspond to the second plurality of control points;
• triangulate the plurality of points on the circle using Delaunay triangulation to form a plurality of triangles within the circle;
• and
• map the plurality of triangles to the hole defined by the second plurality of control points.
