Borehole breakouts do not give an accurate measurement of in situ stress orientation in fractured tight reservoirs. An example is the discrepancy between the maximum horizontal principal compression stress derived from various methods in the Eocene Hetaoyuan Formation, Nanxiang Basin China

Based on a study of 51 coal samples, pores in coals can be divided into plant tissue hole, blowhole, dissolved pore, and intercrystalline pore. Pore structure can be opened, semi-closed, and ink bottle.” The total pore volume shows a positive relationship with the total specific surface area.

Oil shale is a rich petroleum source rock that never got buried deep enough to generate oil and gas. Worldwide, oil shale is a massive resource that potentially could yield a trillion barrels of oil and gas equivalent.

AAPG can trace its first woman member back to 1918, whereas in other countries, women began studying and practicing geology decades later. China is one of those countries. The PROWESS committee recently discovered China’s first female petroleum geologist, Yang Yi, who began studying geology in the 1940s.
