Oil shale in ethiopia
FOR CITATIONS: Yohannes Yihdego, Hilmi S. Salem, Bediaku G. Kafui, and Zarko Veljkovic (2018): Economic geology value of oil shale deposits: Ethiopia (Tigray) and Oil shale occurrence in Ethiopia . Oil shale is said to occur in the south western part of the a country and between Lake Ziway and Lake Abyiata in the valleys of the Bulbul River and its tributaries. The fluvid-lacustrine oilshale bearing formations of Delbi, Mefeso, Lalo-Sapo, Solo, Soyoma, and Mojo-Anchema are an Inter-Trappean continental sedimentation on the south western Plateau of Ethiopia. Coal and oil shale-bearing sediments were deposited in fluvio-lacustrine and paludal depositional environments. The Ethiopian oil shales reach a maximum thickness of 60 m, and contain mixtures of algal, herbaceous and higher plant taxa. Type II and I kerogen dominated the studied oil shales. Oil shale geology is a branch of geologic sciences which studies the formation and composition of oil shales–fine-grained sedimentary rocks containing significant amounts of kerogen, and belonging to the group of sapropel fuels. Oil shale formation takes place in a number of depositional settings and has considerable compositional variation. Oil shales differ from oil- bearing shales, shale deposits that contain petroleum ( tight oil) that is sometimes produced from drilled wells. Examples of oil- bearing shales are the Bakken Formation, Pierre Shale, Niobrara Formation, and Eagle Ford Formation .
The largest resource deposits of oil shale exist in the USA, which are thought to contain 3.7 trillion barrels (590 BCM) of shale oil, forming about 75%–80% of the world’s shale oil’s potential, though only a part of it is recoverable (Dyni 2010). The USA’s oil shale resources are mainly found, in
As indicated above, Ethiopia has a great potential of oil shale resources in most parts of the Country. The Tigray region, located in the north most part of the country, has, in particular, huge deposits of oil shale (Figure 2). The Tigray region is covered by the sedimentary succession of Upper Paleozoic to Mesozoic age, forming parts of the Edaga Arbi Formation, and is exposed as erosion remnants of cliffs that found underlain unconformably by the Basement of Proterozoic Upper Complex Oil shale is an organic-rich, fine-grained sedimentary rock, containing kerogen, from which liquid hydrocarbons (called shale oil) can be produced. The oil shale deposits in the Tigray region are found in the northern parts of Ethiopia, Eastern Africa. Oil shale also known as kerogen shale is an organic-rich fine grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydro carbons called shale oil can be produced. Ethiopia has a huge reserve of oil shale in different localities. Coal, oil shale, oil and gas deposits could possibly play an important role in the future energy budgets of Ethiopia. Inter-Trappean coal and oil shale deposits are distributed on the South-Western and Central FOR CITATIONS: Yohannes Yihdego, Hilmi S. Salem, Bediaku G.
