RE: GoldieHawn I find these two paragrahs interesting. This article is from 2006 and they found fresh water in Shabeel North, which I think they refer to Shabeel 2,and they found Oil in Shabeel 1.Too bad we didn't read this a little better.
Jurassic
Two onshore wells, Dagah Shabel-2 and Biyo Dader-1,
intersected 191 m and 160 m of sandstones in the Adigrat
respectively. Porosity of the sandstones was variable, but
as high as 15%. At Dagah Shabel-2 they produced fresh
water. The reservoir potential of the Middle-Upper Jurassic
deposits of Bihen, Wandere, and Gawan limestones is also
good.
Cretaceous
In the Upper Cretaceous, good clastic reservoirs have been
recognized. Dagah Shabel-1 well intersected very thick
(790 m) fine to coarse-graded fluvial sands of the Nubian
(Yesomma) formation. The well encountered two highly
porous sand units where small quantities (four barrels) of
good quality (33.6° API) oil were recovered. In the offshore,
the Bandar Harshau-1 well penetrated 536 m of Upper
Cretaceous sediments of restricted shallow marine environment
that had porosities of up to 14%.
