Petros Hardas, PhD

Petros received his BA in Geology from the University of Athens in Greece and followed up with an M.S. in 2004 and Ph.D in 2008 at the University of Bochum in Germany. His Ph.D. focused on Upper-'Mid' Cretaceous nannofossils from offshore Suriname (ODP Leg 207, Sites 1258, 1259, 1260 and 1261).

In 2009 he joined PetroStrat, where he worked on Cretaceous and Tertiary well material from the North Sea (UK, Norwegian, Danish sectors), West Africa (Ghana, Cote D'Ivoire, Sierra Leone, Cameroon), North Africa (Egypt, Libya, Morocco), North America (Gulf of Mexico, Eagle Ford Formation), South America (Brazil -Campos/Santos Basins) and the South China Sea (Qiongdongnan Basin). He spent hundreds of days at wellsite for casing/TD picks, biosteering and coring.

Petros joined BugWare in 2014 and has since been assigned numerous offshore assignments in the GoM, as well as maintaining a presence in the North Sea.
