In 1988, Union Gas entered into negotiations for the development of a pinnacle reef to be used for storage of natural gas. The pinnacle reef, known as Dow Sarnia Block "A" Pool, is five kilometres south of Sarnia in the Silurian Guelph Formation (Fig. 1). The reef was discovered using seismic surveys in 1980 and was completed as a gas producer. From 1981 to 1986, the reef produced 87.45 million cubic metres (3.087 billion cubic feet) of gas. Production from the reef ceased in July 1986.
