Carbonates are strange rocks to most exploration geophysicists although they hold more than half the world's petroleum reserves. The geophysicist's exposure to geology in colleges and graduate shools was concentrated on basin analysis, structure, stratigraphy of clastic sedimentary rocks. This estrangement to carbonate sedimentary rocks was further perpetuated in the past two decades, primarily because of the industry's focus on deeper water exploration and development of turbidite sands. Owing to the advancement of geophysical technology, favorable rock physics and superior seismic data quality, geophysics played a critical role in finding many elusive oil and gas traps deep in the ocean....
