The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” conditions of temperature and pressure ( 0 degrees C and under a pressure of 1,013 mbar).
For natural gas, the calorific value (CV) is a measure of heating power and is dependent upon the composition of the gas. The CV refers to the amount of energy released when a known volume of gas is completely combusted under specified conditions. The CV of gas, which is dry, gross and measured at standard conditions of temperature and pressure, is usually quoted in megajoules per cubic metre (MJ/m3).
Contracts that give the right to an investor to buy (e.g. crude oil) at a predetermined level, as the commodity has been sold previously to investors at that level by the banks. An option that gives the buyer (holder) the right, but not the obligation, to buy a futures contract (enter into a long futures position) for a specified price within a specified period of time in exchange for a one-time premium payment. It obligates the seller (writer) of an option to sell the underlying futures contract (enter into a short futures position) at the designated price, should the option be exercised at that price

Namely a company that is considering investing in developing an LNG project will base his economic feasibility study on his belief that he will be doing this in a scenario where oil cost $90 a barrel (and thus he will be able to sell his liquefied natural gas at a price based on this price)
