'Fossil reef limestones can be rocks'.
Barka : Limestones are important rocks to study in Oman because of
the hydrocarbon reservoirs formed, for example from the fossil coral
reefs. Fossil reef limestones can be potential reservoir rocks, said
Prof Michaela Bernecker, associate professor at the Department of
Applied Geosciences at GUtech. He was speaking at an event held in
cooperation with the Geological Society Oman (GSO), titled
'Paleogene Limestones of Oman'. The talk was part of a series
of geology-related topics organised by the GSO every month. These
limestones in Oman were formed very early during the earth formation and
can be differentiated according to their age. "Paleogene limestones
are 25-60 million years old and were deposited in a shallow sea. A very
large part of Oman was flooded 35-55 million years ago," said Prof.
Michaela. Those limestones from South and North of Oman can have
porousness and permeability and they can be reservoir rocks for
hydrocarbons like oil and gas or water reservoir rocks as well. Prof
Michaela and her students have been conducting research on the surface
in Jifnain, Rusayl, Seeb, Duqm and Salalah to study the different
limestone formations. In the subsurface, shallow core samples are taken
by PDO in the area of Ras Al Hamra and analysed by the students, said
Prof. Michaela, who also presented some research results during her
presentation. Similar rocks are found in Saudi Arabia and Iran. Prof.
Michaela studied Geology and Palaeontology at the University of Erlangen
(Germany). During her PhD, she conducted field research in the Oman
mountains. She has been working as Associate Professor at the GUtech
since 2008. Her current projects focus on carbonate facies characterisation and interpretation of outcrop and subsurface data for
industrial applications in the Arabian Peninsula.
