Simulating seismic surveys corresponds to solving the differential equations which control wave propagation under a set of initial and boundary conditions. The most successful numerical technique for solving these equations is finite-difference modeling (FDM). It is based on numerical approximations of derivatives. When an adequate discretization in space and time (which permits an accurate computation of derivatives of the wave equation) is possible, the finite-difference modeling technique is the most accurate tool for numerically simulating elastic wave propagation through geologically complex models. The objective of this course is to provide attendees with a comprehensive theoretical, numerical, and practical description of this important E&P tool. The course includes computer simulations of seismic data using FDM methods.
No longer isolated to the domain of academic, postdoctoral, or postgraduate researchers or similarly trained specialists in the research centers of the oil and gas industry, FDM is today widely accepted as an E&P tool. More and more engineers and interpreters in the industry and even in field operations are using FDM to simulate and design seismic surveys, to develop and test imaging methods, and to validate geological models. Their interest is motivated by the ability of FDM to accurately model wave propagation through geologically complex areas. Moreover, it is often very easy to use. The materials for this course are developed to suit both FDM users and developers. In other words, we hope that interpreters, processors, and scientists will find this class beneficial in their respective tasks.
