I worked for a long time for the seismic department of my company, and switched to the reservoir department only last year. The problems that are tackled are quite different, and the way they are solved as well. So nothing to do with the book I reviewed a long time ago. So after 2 trainings in reservoir simulation, I also read this book that a colleague of mine labeled as the reference book.
When I worked on the common reflection surface stack, one of our biggest issues was selecting the proper optimization algorithms. There are so many for global problems! The book tries to browse through several classical algorithms.
