The European Student Energy Summit (ESES) and the International Association of Drilling Contractors (IADC) European Conference will take place in June and December 2014, respectively.
The ESES event on 20 June is forecast to attract 300 post-secondary students from across Europe. Aberdeen has been selected as host city for the association's European chapter, while Mexico City and Cape Town will host the Latin America and African chapters' events.
The ESES conference was secured following a bid fronted by University of Aberdeen students Malgorzata Olesiewicz and Lora Dimitrova, with the support of the AECC.
The IADC event takes place from 2-3 December, returning to the Scottish city after holding its 2010 annual event there. Around 200 delegates are expected to attend.
Brian Horsburgh, AECC's managing director, said: "AECC, as the National Energy Exhibition Centre, is delighted to be working with students from the University of Aberdeen to bring the ESES event to the region.
"We look forward to welcoming the Conference next summer and are very pleased that the IADC have chosen to return to the city for their December 2014 conference."
