Aberdeen will host its biggest conference this week, with around 40,000 people expected to attend Offshore Europe 09 each day.
The Aberdeen Exhibition and Conference Centre will host the event until September 11th with it being estimated to bring in £25.94 million for the local economy.
It attracts people from the oil and gas industry, including drilling firms, engineering contractors and people studying in the sector.
Lord Provost of Aberdeen Peter Stephen said the conference is an "excellent opportunity" for businesses and the area to showcase their talent.
"Offshore Europe, as one of the world''''s foremost oil and gas events, contributes hugely to this goal," he added.
Gordon McIntosh, corporate director of enterprise, planning and infrastructure at Aberdeen City Council, said that the event is a "unique opportunity" for the region to welcome key players in the industry.
Edinburgh is also performing well in the conference sector, having recently been chosen as the venue for the London Bullion Market Association''''s annual Precious Metals Conference.
