SPE Young Professional Workshop: Innovation and Entrepreneurship
Speaker(s) Richard Kruger, CEO, Imperial Oil; Pat Carlson, CEO, Seven Generations

Ten years ago, news reports frequently cited peak oil as a looming problem facing our world. Technology and innovation has since been developed that allows us to tap into rocks that were previously deemed impossible to extract oil from, reversing this trend. The Western Canadian Sedimentary Basin has been a leader in this movement with entrepreneurs using new technology to develop our resources in a safe and reliable way. 

In this workshop, we'll highlight some of these stories on innovation and entrepreneurship with talks from industry leaders Richard Kruger CEO of Imperial Oil and Pat Carlson CEO of Seven Generations.

This will be followed by a talk and activity from Kinetica Ventures on how to take a good idea from the back of a napkin to a fully realized company. Then, join us for a networking cocktail reception post workshop.
