G. Shanmugam’s activities on deep-water sandstones in China in 2014


His research and publications on “Deep-water petroleum sandstones” have been gaining increasing attention among the oil companies, universities, and the government in China. Three activities in 2014 are:
1. In April 2014, his 2012 book “New perspectives on deep-water sandstones: Origin, recognition, initiation, and reservoir quality” (Amsterdam, Elsevier, Handbook of petroleum exploration and production, v. 9, 524 p.) was translated and published in the Chinese language. This was done by the Chinese government and PetroChina. See book cover below.

2. On May 12 and 13, 2014, he organized a two-day Workshop on “Deep-water sandstones” for the national audience at the China University of Petroleum in Qingdao (Eastern China). See a group photo below.

3. On May 15, 2014, G. he organized a one-day Core Workshop for the Yanchang Oilfield Research Institute in Yan’an (Central China) using their most recent core. The Yanchang Fm. in the Ordos Basin is one of the biggest petroleum producers from deep-lacustrine sandy debrites in China.
              In these workshops, the Chinese geoscientists were keenly interested in the recent debate on baroclinic currents (interenal waves and tides) and their role on developing deep-water sandy reservoirs See AAPG Bulletin debate 2014)
4. In August 2014, he was appointed as an Editorial Board Member of the Elsevier Joornal:
PETROLEUM EXPLORATION AND DEVELOPMENT.
