Shale oil extraction Energy estimates that the "ex-situ" processing would be economic at sustained average world oil prices above $54 per barrel and "in-situ" processing would be economic at prices above $35 per barrel. These estimates assume a return rate of 15%. Royal Dutch Shell announced in 2006 that its Shell ICP technology would realize a profit when crude oil prices are higher than $30 per barrel ($190/m), while some technologies at full-scale production assert profitability at oil prices even lower than $20 per barrel ($130/m). To increase the efficiency of oil shale retorting and by this the viability of the shale oil
Barrel of Monkeys principle be assembled in this way. The only unusual characteristic of the monkey is that its arms, legs, hands and feet are able to twist around each other to form many stable links. In this, they resemble protein molecules which can also link together in many ways. The resulting assemblies simulate biologically important structures, but their symmetry follows general geometric principles. The monkeys provide a 'hands on' approach to understanding these principles. "Barrel of Monkeys" is also called as Bandar Keela and is famous in south Asian countries.
