Abstract
A model1ing study aimed at providing a
better understanding of the hydrocarbon accumulations on the SW
flank of the Dead Sea graben in Israel has been performed. It
considers the recent geochemical finding that the source rock of
the hydrocarbon occurrences in the area is the Senonian
bituminous chalk and marl, buried in the central Dead Sea graben.
The study investigates the effect of the regional geological and
hydrogeological conditions, associated with the physical
properties of the rock and fluids, on the migration and types of
hydrocarbon accumulations. The investigation was performed by
means of a three-phase, two-dimensional, numerical reservoir
simulator. Typical cross-sections, through potential anticlinal
hydrocarbon traps, were considered. The study analyses possible
hydrodynamic flushing in the water-flow direction, as well as
counter-current migration in a direction opposite to the
potentiometric water gradients, from the Dead Sea graben upwards.
