MR. ANDREW PEPPER is Director of This is Petroleum Systems LLC - "t!Ps" - a consulting service that conducts studies, research into new workflows and tools, and training in the field of Petroleum Systems Analysis. The scope is both conventional and unconventional and global - but with current focus on the Gulf of Mexico and Permian Basins. He has held functional roles including responsibility for internal training at BP, Hess and BHP Billiton since 2000. Prior to forming t!Ps, from 2012-2015 he was VP of Geoscience and VP of Unconventional Exploration at BHP Billiton. At Hess, from 2003- 2012, Andy was Chief Geologist and Director of New Ventures (Conventional and Unconventional). At BP, in Houston, he led the Petroleum Systems Network from 2000-2003, after working in the team that positioned and delivered BP's exploration dominance of the sub-salt of the deep water Gulf of Mexico. His early career as an international exploration geologist was punctuated by a rotation into the Sunbury Research Center from 1985-1989, where Andy performed technical studies and conducted research in the (then developing) fields of organic geochemistry and basin modeling. He has presented many oral papers beginning 1989, and is best known for publication of a trilogy of papers concerning petroleum generation and expulsion in 1995. These algorithms are now coded into modern basin modeling packages. In 1981 Andy received a BSc 1st Class Honors in Geologic Sciences at Leeds University, UK, where he is currently a Visiting Academic.
