In recent decades, significant deposits of oil shale have been found in Jordan, Syria and elsewhere. As with the tar sands in Canada, extracting usable liquid petroleum from shale oil involves considerably more effort and cost. Since the prices of crude oil have remained at historically high prices, and processes have improved, production of oil from shale has become more economically viable. Brazilian oil company Petrobras has been working on oil shale production in Brazil and has now signed an agreement to study the feasibility of applying their technology to a shale deposit in Jordan. The Jordanian deposit has potential reserves of 1.7 billion of of crude oil.
