Abstract: Oil Migration Pattern in the Sirte Basin
M. Roohi, R. M. Aburawi
Sirte Basin is an asymmetrical cratonic basin, situated in the north-central part of Libya. It covers an area of over 350.000km2 and is one of the most prolific oil-producing basins in the world.
Sirte Basin is divided into large NW-SE trending sub-parallel platforms and troughs bounded by deep seated syndepositional normal faults. A very unique combination of thick sediments with rich source rocks in the troughs vs. thinner sediments with prolific reservoir rocks on the platforms accounts for the productivity of the basin.
Analysis of oil migration pattern in the Sirte Basin will certainly help to discover the remaining reserves, and this can only be achieved if the important parameter of structural configuration of the basin at the time of oil migration is known.
The present paper is an attempt to analyse the time of oil migration, to define the structural picture of the 4 Basin during the time of migration and to delineate the most probable connecting routes between the hydrocarbon kitchens and the oil fields.
