Abstract :
Middle Eastern source rocks were deposited in interconnected coastal seaways that formed a global system of source rock provinces. For example, in the Turonian- Cenomanian the Zagros Basin's Ahmadi/Khatiyah source rock was deposited in a seaway that extended from the Middle East to the South Atlantic and even to the north polar regions. Source rocks deposited in this seaway have generated significant petroleium in Angola, Gabon, Venezuela, Colombia, Tunisia, the Gulf of Mexico, Brazil and the West Siberian Basin, among other areas. Upper Jurassic organic-rich beds were deposited in similar global seaways. Upper Jurassic and Middle Cretaceous source rocks such as these have generated more than 50% of the world's discovered petroleum reserves.
Conoco's Advance Exploration Organization focuses its efforts on identifying highly prospective underexplored areas. Since regional geoscience research is required to support this work, we have created a computer system that facilitates mapping of global seaways for all of the world's major source- rock- rich time periods. Viewing the whole globe for any time in the geologic past allows us to project extensions of highIy petroliferous geology, such as that of the ancient Tethyan realm, into underexplored areas. This study details usage of this methodology to identify high- potential new plays in the Tethyan basins of the southern republics of the Soviet Commonwealth. Iran. and Afahanistan.
