have added 6 trillion cubic feet to the Area 4 reserves base, bringing them
to estimated 23 trillion cubic feet in place, with potential of 75 trillion
cubic feet throughout the Mamba complex. “Mamba South 2” was drilled
in ,1918 m of water to a total depth of 4,300 m, and intersected 60 m
of gas pay in good quality Oligocene reservoirs. While “Coral 2” was
drilled in 1,950 m of water to a total depth of 4,725 m and encountered
140 m of gas pay in good quality Eocene reservoirs

.
In general, including OAPEC members discoveries, available
data suggested 103 discoveries in 2012, 63 of which were oil and
40 were gas discoveries. It is notable that 16 discoveries were
covered by 1,000 m of water, as shown in
Table (F)
. This clearly
indicates the increasing importance of deep waters as an exploration
target, supported by technology development in different aspects of
petroleum industry.
