Subsalt Imaging: Snapshots in Time,
Reflections, and Next Steps
Honorary Lecturer 2016 - North America
Abstract: Many individuals, companies, consortia, and joint ventures have contributed to the current industry capabilities in subsalt imaging. The lecture will focus on the thought processes, business needs, and technologies that led to BP sponsoring two significant field trials of wide-azimuth acquisition technologies in 2005-2006 and how BP and the industry have responded since that time. Seismic acquisition is a necessary but not sufficient condition to achieving the subsalt image. Time processing, imaging algorithms, and the velocity model also are required to achieve a high-quality image and, as such, I will discuss some key enablers in the journey toward the industry’s current capabilities.

Bio: Scott Michell joined Conoco in Ponca City, Oklahoma in 1991 as a seismic processor. The link between seismic acquisition and the final image became apparent, particularly as the industry moved from predominantly 2D to 3D data and from time imaging to depth imaging. He worked closely with the R&D teams and the processing teams to deliver high-end land and marine images with a variety of challenges including permafrost and other complex near- surface issues, multiples, anisotropy, and the challenge of moving from time imaging to depth imaging.
Upon joining BP Exploration in 1997 Michell took up the challenge of understanding acquisition footprint on TZ data and subsalt imaging. He was involved in designing and implementing a unique joint venture of five oil companies called SMAART, which was formed in 1998. As the BP technical representative, Michell worked with the SMAART Joint Venture to investigate and apply strategies for removing multiples from beneath salt and later to investigate the impact of acquisition on subsalt imaging. The SMAART JV was awarded the SEG Distinguished Achievement Award in 2008. After his involvement with the SMAART JV ended Michell went back to the depth-imaging problem examining strategies to build complex salt models and incorporating multiple data sets. He was part of the BP team that developed, designed, and implemented both the WATS technology and the OBN applications in the Deep Water GoM campaign. After the OBN and WATS surveys, Michell managed a team of leading scientists in BP’s Advanced Seismic Imaging Flagship group. He has also been the seismic delivery manager for North America Gas and Alaska. He is currently the seismic delivery manager for the Gulf of Mexico region, which has just completed an extensive 4D OBN campaign and two very large 3D VSPs.
