Time Series EROI for Canadian Oil and Gas
Alexandre Poisson and Charles A. S. Hall *
Study presents a calculation of the energy return on investment (EROI) of Canadian unconventional and conventional oil and gas and find a 63% increase in energy investment in the O&G sector overall over the last two decades. This increase in energy invested has increased energy production just 18%. EROI for the sector and for tar sands alone are estimated at 11.1 and 4.1 respectively.
