- An integrative geologic model for the opening of the Red Sea and Gulf
of
Suez with a focus on the impact of tectonics on synrift depositional facies,
and high-resolution, standardized stratigraphic correlation of the region
bordered by six different countries (Egypt, Saudi Arabia, Sudan, Yemen,
Eritrea, and Djibouti) which use different stratigraphic terminologies.
2. An evaluation of pre-salt (pre-Late-Miocene) and pre-rift (JurassicEocene) sedimentary packages and petroleum plays in the Red Sea basin
constrained by paleofacies reconstruction and correlatable source rocks
and geochemical data.
3. Play fairway mapping of hydrocarbon prospectivity in selected key areas
in the Red Sea based on a synthesis of information from wells, seismic, and
other data.
4. An atlas of seismic, stratigraphic, and well data for quick reference and use.
The Red Sea Basin (RSB) rift (Figure 1) runs for 2,250 km in an
NNW-SSE trend between the African and
Arabian plates and has a maximum width of 355 km. The sea-floor spreading is
about 1.6 cm/year from
the spreading center so that divergence between Arabia and Africa is taking
place at a rate of about 3.2
cm/yr. RSB is considered to be an active example of early-stage ocean
opening and thus offers significant
clues to structural and sedimentary evolution from a continental rift to a
passive margin drift setting.
An interesting feature of RSB rift is that the spreading center, rather than
being a “mid-ocean ridge,”
is actually a trough (>3000 m deep). Closely associated with RSB are the
characteristics of petroleum
systems (source to entrapment) in such settings, thus offering valuable
analogs for other, older rift-drift
margins in addition to the RSB being a highly prospective young petroleum
basin setting.
