Tewfik, the former Exploration Manager and Deputy General Manager of Unocal Egypt.  The company has dealt with more than 100 oil companies in the Middle East, North Africa and North Sea.

EREX activities include integrated geological, geophysical and reservoir engineering studies covering evaluations of bid rounds, exploration acreage, exploitation and field development studies.

Services include: 2D/3D seismic interpretation, sequence stratigraphy, biostratigraphy, sedimentology, petrophysical log analysis,  structure and velocity modeling,  structural restoration, fault seal analysis, 3D stochastic reservoir characterization and modeling, reservoir engineering studies, production forecast, history match and 3D dynamic simulation. The studies are supported by strong geological, geophysical and engineering software capabilities.

EREX Consultants have been offering international technical training courses and field seminars to the Petroleum Industry in North Africa and the Middle East since 1991.  The courses cover important topics for geologists, geophysicists and petroleum engineers.

The company carried out a non-exclusive study together with the Egyptian General Petroleum Company (EGPC) and GAPS Geological Consultants of the U.K. in 1988, evaluating the Miocene sandstone reservoirs in the Gulf of Suez, as well as eleven oilfields. The study was very successful and has been purchased by most of the major oil companies.  The company is currently carrying out several geological, seismic and prospect evaluation projects for major oil companies over open and licensed acreage. 

The company was the technical representative for several oil companies such as Lasmo, UK,  Sipetrol, Chile, and Sojitz, Tokyo carrying out evaluations of exploration blocks and farm out opportunities.  EREX has activities outside Egypt in Yemen, Libya, Syria, Algeria and Sudan.
