The Bahariya Formation is a complex succession of mixed clastic-carbonate
deposits of Cenomanian age that formed on a broad, tidally-influenced ramp on
the southern margin of Tethys. It is a principal oil reservoir in the Western
Desert of Egypt. Over the past twelve months, reservoir characterization studies
of Bahariya producing fields along the Khalda Ridge (Salam, Hayat, Yasser and
Kenz fields) have resulted in a more complete understanding of the Bahariya
depositional system as well as a number of successful infill drilling locations.
The studies include full integration of depth-converted seismic
, wellbore and
production data within a sequence-stratigraphic framework and the extensive use
of geologic
modeling
for data visualization and sand mapping.
