A research document by the International Association for Energy Economics (IAEE) claims that Ethiopia has 3.89 billion tonnes of oil in Tigray province. Excerpts from the document.
Ethiopia has 3.89 billion tonnes of oil shale located in Tigray province, which borders Eritrea. However, there is currently a lack of interest in exploring the shale oil, possibly due to a previous dispute over the area which led to conflict between Ethiopia and Eritrea. This conflict continues.
In addition to the region of Tigray, there is a smaller deposit of 100-120 million tonnes at the Delbi Moyen coal development, southwest of Addis Ababa, although Ethiopia has plans to utilise this for manufacturing urea fertiliser.
