If you are asking for energyequivalency, a commonly used factor in the oil industry is 1 barrel of oil =6,000 cubic feet of natural gas.

Therefore, 1 TCF of natural gaswould equal 170 million barrels of oil, approximately.

IF Mukuyu is claimed to hold 225million boe atm…. (as seen in chart above ?) then IVZ's Mukuyu field = 1.32 Tcf atm !!

What's the BOE equivalent of 1 trillion cubic feet (TCF) ofGas

1 Trillion cubic feet (1Tcf) is a measurement of natural gas used by the U.S. oil and gas industry, equal to about one quadrillion British thermal units.

1 US$ per (Quadrillion BTU) =

9.4781712 × 10^-19 m^-2 kg^-1 s² U.S. dollars
