  30. Results of Quiz… 1. What is the usual unit for a quantity of crude oil? • 1 barrel = 1 bbl = 42 U.S. gallons • 1+6 zeros = 1 MMbbl • 1+9 zeros = 1 Bbbl • 1 metric ton = 7.5 barrels • Giant field: 100 MMbbl = 0.1 Bbbl

  31. Results of Quiz… 2. What is the usual unit for a quantity of natural gas? • 1000 standard cubic feet = 1 MCF • 1 MCF+6 zeros = 1 BCF • 1 MCF+9 zeros = 1 TCF • Roughly: 6 MCF gas = 1 Bbl crude

  32. Cost of gas= 0.405 $/Ccf
