... The "Oil Mine" concept is based on methods which have been used for generations, and consists of using tunnels and caverns in a way which permits production and transport of oil and gas from underneath the sea floor. 'Compared to oil and gas production from platforms, the "Oil Mine" offers many...

... A group of vertical cylindrical rock caverns is the basic idea of the POLYTANK concept. Vertical caverns can sometimes offer a good solution to underground storages in rocks with horizontal discontinuities. The small roof area of vertical caverns compared to horizontal tunnels gives low cost for...
