Deepwater turbidite reservoirs hold some of the largest petroleum reservoirs and thus are important exploration targets. By identifying and mapping the diverse architectural elements of the turbidite system and placing them within the correct geologic framework, a skilled interpreter can predict which components of the system are more likely sand or shale prone. Seismic data and seismic attributes also provide insight into the connectivity or compartmentalization of different parts of the reservoir which can be used to estimate the number of wells needed to drain the reservoir.

This debate began decades ago: How much of the planet's natural gas is abiotic – made up of methane with nonbiological origins? At times, the scientific back-and-forth argument has resembled a slow-motion tennis match, with a new volley coming every few years. Now, Daniel Xia thinks he has helped deliver a winning smash across the net. His findings were most clearly laid out in a recent article “Validity of geochemical signatures of abiotic hydrocarbon gases on Earth,” by Xia and coauthor Yongli Gao, published in the Journal of the Geological Society.
