Event Details

Abstract:
Simultaneous source seismic surveys, using a method referred to as source blending, use more than one seismic source at a time. This technology is part of the progression of seismic surveys to obtain denser sampling and better seismic images. Simultaneous sourcing uses multiple seismic sources, producing seismic signals that overlap with the signals from the other seismic sources. This increases the efficiency of seismic exploration by decreasing the time between shots, significantly reducing the cost and time needed to acquire a seismic survey. The main challenge to the use of simultaneous sources is the separation of signals from the different sources. This separation is accomplished by using concepts from compressive sensing by way of sparse inversion, a method of getting the simplest answer to the inversion of a matrix equation. While this involves a significant computational expense, the decrease in the acquisition cost is even more substantial.

Biography:
Ray Abma is the SEG’s 2017 Distinguished Lecturer. He is a Senior Research Geophysicist in the Upstream Technology group in BP. Ray received a Ph.D. from Stanford University in 1995 and was with the Stanford Exploration Project. He has worked for Western Geophysical, Shell, ARCO, and now BP. He has spent more than a decade developing simultaneous and coded seismic source technology. In 2012 Ray and his team won the BP Technology Award for the development of marine simultaneous source acquisition. Later in 2012 Ray and the simultaneous source team won the BP Helios award, the highest award within BP. Ray’s interests are seismic interpolation and regularization, multiple and noise attenuation, sparse inversion, coded source seismic acquisition, and simultaneous source acquisition. He is a member of SEG, EAGE, GSH, and SIAM.

Organizer

Dhahran Geoscience Society

The purpose of the society is to help provide for the technical and professional development of its members in geology, geophysics, and related sciences, especially in the exploration for, and development of, petroleum and mineral resources within the Arabian Peninsula.

The society activities include regular monthly meetings, field trips to local and out-of-kingdom locations, technical seminars, special projects and publications. Membership includes subscription to the quarterly geoscience journal "Geo Arabia". The society is also a co-sponsor of the regional "GEO" conferences.

Membership of the Dhahran Geoscience Society is open to all Eastern Province geoscientists. The Dhahran Geoscience Society is an affiliated society of AAPG, EAGE & SEG.
