About the Author

Hezhu Yin

Dr. Hezhu Yin is a Geophysical Advisor with ExxonMobil. He earned a B.S. in Geophysical Well Log Engineering from China University of in 1982, and a Ph.D. in Geophysics from Stanford University in 1992.

From 1982 to 1987, Yin taught and researched at Daqing Petroleum Institute with focus on instrumentation. He designed and developed a Multi-functional Panel of Triple-combo Logging Suite for Daqing Oilfield Well Logging Company. From 1987 to 1992, Yin joined Stanford Rockphysics and Borehole Physics (SRB) Research Project with focus on experimental rockphys- ics, and contributed 17 articles to Standford Rockphysics and Borehole Physics Project Research Volumes. After a year of post-doctorate research at Stanford, Yin acted as a research associate and adjunct professor at Lamont-Doherty Earth Observatory of Columbia University from 1993 to 1995. At Lamont, he taught graduate student courses and his research focused on designing and executing the Ocean Drilling Program (ODP) borehole geophysical operation, and borehole geo- physical research for ODP drilling legs.

In 1995, Yin joined Exxon Production Research Company (now ExxonMobil Upstream Research The AAPG Bookstore Geological Society Publishing House Company, EMURC). His first assignment with Exxon was on Resistivity Tool Response Forward P.O. Box 979 Unit 7, Brassmill Enterprise Centre and Inverse Modeling. From 1995 to 2000, he developed numerous 1-D and 2-D forward and Tulsa, OK 74101-0979 Brassmill Lane, Bath BA13JN practical inverse modeling codes with analytical, finite element, and hybrid methods to simulate U.S.A.

Yin is author and coauthor of 59 publications, and inventor and co-inventor of 9 US and other patents covering his 28 years of academic and industry career. Currently as a Geophysical Advisor at ExxonMobil, Yin is working on world class Extended-Reach-Drilling (ERD) and HAHZ wells’ logging operation, geosteering, and formation evaluation from the active development fields of ExxonMobil in West Africa, North Sea, Middle East, and Far East.
