ABSTRACT: Underground Storage in Ontario
J. Manocha, T. R. Carter
Underground storage of liquified petroleum products and natural gas is a provincially significant activity in Ontario with large economic benefits for the companies involved. There are currently 19 active natural gas storage pools in Ontario, with a working capacity of approximately 185 bcf (5.24 billion cubic meters). There are 61 active solution-mined liquid hydrocarbon storage caverns with a total useable capacity of approximately 17 million bbl (2.7 million cubic meters). Eighteen of the active natural gas storage pools utilize depleted Guelph Formation (Niagaran) reefs. The liquid petroleum product storage caverns are constructed within salt horizons of the Salina B and A-2 Units.
With steadily increasing demand for natural gas in Ontario, there has been a recent increase in demand for additional storage capacity. There is now a significant economic incentive for exploration companies to discover new reefs in Ontario not only for the value of potential oil and gas production, but for their storage value as well. There are also a number of depleted or nearly depleted natural gas reservoirs in Ontario, as well as solution-mined caverns created as a result of solution mining activities, with potential for conversion to storage. The authors have evaluated these potential storage sites from economic, environmental, and resource management perspectives.
