Conventionally Mined (Hard Rock) Storage Caverns
Rock formations on the crust of the earth are a natural storage environment – indeed, the same environment used by nature to store crude oil and gas. Using conventional mining techniques, our Fenix & Scisson division constructs caverns within these hard rock formations to provide highly protective and economical storage for hydrocarbons such as natural gas, propane, butane and crude oil.
Whether developed in abandoned or depleted mines or newly constructed in rock formations – igneous, metamorphic or sedimentary – conventionally mined underground storage facilities have been designed, engineered, constructed and managed by PB Energy Storage Services for more than 40 years. With experience of 75 mined storage caverns with a combined total capacity of nearly 21 millions barrels, PB Energy Storage Services has perfected many construction techniques that are now a world standard.
