GEOGRAPHICAL
SETTING
The Magon block is located offshore Tunisia,
in the Gulf of Gabes, about 80 km South-East of Sfax city. The
water depth is around 65 m. The Magon block is located between
two giant Ashtart oil and Miskar gas fields.
ACREAGE
124 km².
PREVIOUS
EXPLORATION
About 270 km of seismic have been recorded within the Magon
block. No wells have been drilled within the block. However, the
wells drilled at the vicinity of the block such in Ashtart and
Miskar productive oil and gas fields may provide additional
data.
GEOLOGICAL
SETTING
The Magon block is bounded at
the West by the Ashtart North West-South East faulted anticline,
and by the Jugurtha structure at the East. The Magon block lies
to the pelagian platform dominated by a carbonate deposits
during the Cretaceous to Eocene time. This platform is affected
by distensive tectonic creating a series of horsts and titled
fault blocks favoring a facies change and the development of mud-mounds
and reefal deposits.
HYDROCARBON
POTENTIAL
Reservoirs :
The main carbonate reservoirs are the Ypresian
nummulitic limestone; the para-reefal and/or chalky limestone of
Abiod Campanian formation and the Coniacian and Turonian oolitic
and bioclastic carbonates of Bireno and Douleb Members.
All these reservoirs are productive both in the nearby Ashtart
and Miskar fields.
Source Rocks : Oil and gas in the nearby
Ashtart and Miskar fields seems to be generated by the Ypresian
organic-rich limestone of the Bou Dabbous formation.
Traps :
The main trap include faulted blocks and four
way dip closure.
