Natural Gas: Inter-Fuel Price Equivalents (US Currency)

---------------------------------------------------------

ONE CENT per MMBtu

        = 5.8 Cents per Barrel crude oil

        = 6.4 Cents per Barrel fuel oil

        = 5.2 Cents per Barrel naphtha

        = 4.5 Cents per Barrel LPG (r)

        = 4.1 Cents per Barrel LPG (P)

        = 3.8 Cents per Barrel LNG

ONE CENT per MMBtu

        = 0.42 Dollars per Tonne crude oil

        = 0.40 Dollars per Tonne fuel oil

        = 0.45 Dollars per Tonne naphtha

        = 0.47 Dollars per Tonne LPG

        = 0.52 Dollars per Tonne LNG

ONE DOLLAR per BARREL

        = 17 Cents per MMBtu crude oil

        = 16 Cents per MMBtu fuel oil

        = 19 Cents per MMBtu naphtha

        = 22 Cents per MMBtu LPG (r)

        = 24 Cents per MMBtu LPG (p)

        = 26 Cents per MMBtu LNG

ONE DOLLAR per TONNE

        = 2.4 Cents per MMBtu crude oil

        = 2.5 Cents per MMBtu fuel oil

        = 2.2 Cents per MMBtu naphtha

        = 2.1 Cents per MMBtu LPG

        = 1.9 Cents per MMBtu LNG

    ONE CENT per US gallon LPG = 10 CENTS per MMBtu

 

Oil and Coal Equivalent

-------------------------------------------------------

1 million tonnes Oil per Year

        per year = 1.1 mrd m3 gas (1.3 mrd Groningen)

                 = 1.5 million tonnes coal

                 = 815 000 tonnes LNG

                 = 890 000 tonnes LPG

                 = 0.04 Tcf gas (42 trillion Btu)

        per day  = 115 million ft3 gas

                 = 3 million m3 gas

                 = 30 500 barrels LNG

                 = 26 000 barrels LPG (r)

                 = 28 300 barrels LPG (p)

                 = 20 000 barrels oil

1 million tonnes Coal per Year

        per year = 0.7 mrd m3 gas (0.8 mrd Groningen)

                 = 640 000 tonnes oil

                 = 525 000 tonnes LNG

                 = 580 000 tonnes LPG

                 = 0.03 Tcf gas (27 trillion Btu)

        per day  = 75 million ft3 gas

                 = 2 million m3 gas

                 = 19 700 barrels LNG

                 = 16 800 barrels LPG (r)

                 = 18 200 barrels LPG (p)

                 = 12 900 barrels oil

10 000 barrels Oil per Day

        per year = 0.6 mrd m3 gas

                 = 500 000 tonnes oil

                 = 780 000 tonnes coal

                 = 0.02 Tcf gas (21 trillion Btu)

        per day  = 58 million ft3 gas

                 = 1.5 million m3 gas

Rich Gas = natural gas having a gross calorific value of 41,868 kJ/m3.

This term is used particularly for the natural gas from the North
Sea and from Algeria.

 

Degree-days = the number of degree-days of a day is calculated on the

basis of a reference temperature set by experience at 16.5 C; it gives the

difference between that reference temperature and the daily mean temperature

if the latter is the lower.

The number of degree-days of a year is the sum of the degree-days registered

for each day of that year.

 

G-factor = invoicing factor representing the average monthly cost of

natural gas at the Belgian border in francs per gigajoule.
