Pupils in Aberdeen have discovered new oil fields - albeit virtually.
Young chemistry students have been competing in the annual Oilism competition, which creates virtual realities for the secondary pupils to enter the world of petroleum exploration. Teams from eight secondaries in Aberdeen and Aberdeenshire take on the roles of oil and gas companies entering new petroleum provinces, starting with a budget of $100 million (pound;52.9 million) and aiming for a return by striking black gold or investing in other teams' opportunities.
Pupils studied seismic surveys, bid for licences, competed for rigs and chose where to drill wells.
The aim of the competition is to tackle the industry's skills gap and encourage youngsters to consider careers in oil and gas exploration.
Harlaw Academy won the Scottish heat, organised by Chevron and Aberdeen City Council, and will represent Scotland in the international competition in London next year.
