The application of rock physics in exploration and development of hydrocarbon reservoirs has increased considerably over the last two decades. The number of technical sessions dedicated to a specific topic or theme in an SEG Annual Meeting directly reflects the activity and interest in the subject. Twenty years ago, there were only two sessions labeled rock physics. Ten years ago there were five, and last year's Annual Meeting in Houston featured an impressive 10 sessions in the technical program dealing specifically with rock physics. Some of the factors that have contributed to the ascendancy of rock physics include: advances in seismic processing generating amplitude data with enough fidelity to be quantitative in predicting rock properties, the need for derisking subsurface factors of prospects from an economical perspective, and the increase of knowledge on the topic in the industry.
