What is it about?
Rocks have memory. The present day rock properties are reflecting the geologic past, and this knowledge should be included during quantitative interpretation of reservoir properties from seismic data. In this study, we show how we can integrate the study of geological processes (deposition, burial, compaction, erosion) with the study of rock physics and seismic properties. This help us to better predict rock types and pore fluids from seismic observations.

Why is it important?
This is important during derisking of petroleum prospescts and to avoid expensive dry wells during exploration in areas with complex geology. It is also important to better understand the subsurface in genereal, and this knowledge can also be beneficial beyond oil and gas exploration, for example during CO2 sequestration and geothermal drilling.
Perspectives
I think this paper is a good culmination of ideas developed over a period of many years, and it really demonstrates the power of integration across disciplines that traditionally have been operating in silos.
