A multitude of geological data suggests that the petroleum system is in place. Rich, voluminous source rocks, likely migration paths, good reservoir rocks and huge traps all make the Seychelles offshore basins a tempting target for companies ready to explore a frontier province.

Read this carefully (adapted from ’BP Statistical Review of World Energy’): "Proven reserves is the estimated quantities of oil which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under current economic and operating conditions."
Iman Hill has risen through the ranks from petroleum engineer to senior management roles with Shell and BG. She talks to GeoExpro about the skills needed to thrive in the modern oil industry, the paucity of women in high-ranking jobs – and about the pleasures and pitfalls of juggling a successful career with the demands of a young family.
With relatively easy access from Longyearbyen, the Festningen Section is a very popular geological attraction that displays an almost complete section of sedimentary rocks throughout the Mesozoic. Scientists, students and oil company geoscientists come every year from all over the world to learn basic principles of sedimentology and sequence stratigraphy.
In the barren landscape of the Syrian desert you may find an occasional drilling rig exploring for hydrocarbons. In the years to come several more rigs are expected to enter, as the Syrian authorities are now actively encouraging international oil companies to acquire acreage and drill for oil and gas. The next frontier, however, is the offshore, where no wells have yet been sunk.
The introduction of Q-Marine* technology a few years ago has given WesternGeco a competitive edge, the company claims. In the Oslo Technology Centre they are proud of having been crucial in the development of seismic technology that, beyond any doubt, has given some oil companies value for money.
After only a few small discoveries in what appeared to be favourable geological conditions, a major study of the petroleum system of the huge, immature basin was conducted. The subsequent well hit oil in Lower Tertiary sandstones, and the discovery was later proven to be a giant (>500 million bbls of recoverable oil) within the prolific Central African Rift.
Souring oil prices have inspired NAM to consider redeveloping one of Europe’s largest oil fields. A 3D high resolution seismic survey will lower the structural uncertainties and horizontal drilling, in combination with new recovery procedures, means that the abandoned Schoonebeek Field could yield a further 100 million barrels of oil.
