Latest Patents

Harlan holds a patent for a method titled "Tomographic estimation of seismic transmission velocities from constant." This method enhances velocity models, allowing constant-offset migrations to estimate consistent positions for reflectors. The patent introduces a technique for converting inconsistencies in reflector positioning into equivalent errors in modeled travel times. This advancement enables conventional traveltime tomography methods to refine the velocity model, resulting in a more accurate migrated image of the subsurface. Additionally, the estimated velocity model can identify geologically significant anomalies, such as low-velocity gas accumulations and irregular near-surface weathering. The procedure can also be iterative, allowing for alternating improvements in reflector positions and the velocity model.
