Slide 2: Most of the recoverable oil in the Persian Gulf region lies within the so-called Arabian-Iranian oil province or Median Trough--a very old structural basin. The Median Trough has remained at low latitudes within 30 deg. of the Equator where biologic productivity is high. For the last 250 million years the Median Trough has been the site of repeated accumulation of organic-rich marine sediment source rocks in large shallow depositional basins, with subsequent formation of suitable hydrocarbon traps.
