Automatic, Dense And Volumetric Picking For High-resolution 3D Tomographic Model Building

Summary As survey sizes are steadily increasing, 3D tomogra phy as the key component of today’s velocity model buildin g workflows has to be performed on large data volumes within acceptable turnaround times. To provide high resolution velocity models, dense volumetric pickin g is required. This leads to even larger data volumes. I t is therefore paramount to automate as many processing steps as possible to free the time of the geophysicist fo r the necessary QC. In this paper we present a modified workflow for high-resolution 3D tomography addressing the need for process automation. We are putting the emphasis of this paper on data preparation and the quality control of the inversion phase. The presented workf low allows performance of high-resolution tomography work on large data volumes over a significantly reduced cyc le time.
