The province of Alberta is home to one of the World’s largest sedimentary basins. And the Oil and Gas industry has been Alberta’s main source of economic prosperity for more than half a century. The oil sand deposits are the province’s biggest oil producers, and due to the nature of bitumen and heavy oil, enhanced oil recovery techniques such as Steam- Assisted Gravity Drainage or SAGD are required. Oil and Gas and in particular the oil sands operations, have raised lots of negative Environmental concerns. And In addition, in recent years the government and companies have faced immense liabilities by the nonproducing wells. Alberta has one of the most polluting Grids across Canada and this is mainly because of Fossil Fuels. All these issues raise the demand for more alternative reliable sources of clean energy with little environmental impacts. Given the huge Sedimentary Basin and existing infrastructure geothermal energy has a good potential to be investigated and developed in Alberta. Geothermal Energy is the heat derived from the earth’s subsurface, can be Harnessed for Clean Electricity generation or space heating applications. The main advantages of geothermal energy is being weather independent, and its very high capacity factor. By providing sustainable clean energy solutions using Geothermal potential, Renewable Energy can penetrate the Alberta Grid to lower the GHG emissions, and since infrastructure such as drilled wells already do exists, a big portion of money needed for the initial investment can be eliminated. This project provides solution for decommissioned wells which are hazardous risk to human health and the environment and huge financial liabilities for government and companies. Converting just 10 percent of Alberta’s thousands suspended wells to geothermal can create business and work for hundreds of services and defer the high cost of well abandonment for companies Plus additional potential revenue from carbon tax credit by Reducing GHG emissions.
