OIL INDUSTRY CONVERSIONS - dieselduck

Oil Industry - Handy Conversion Information

Crude petroleum, and the refined products made from crude oil, are normally measured either by volume in gallons and US barrels, or by weight in tons or tonnes. The relationship between volume and weight is usually measured by density in the United Kingdom (the alternative measure is relative density or specific gravity). American oilmen usually reckon quantities of oil produced, moved or processed in barrels per day (bpd or b/d). The loose but simple rule of thumb for conversion is that a barrel a day is roughly 50 tonnes a year, but the relationship varies according to density and so according to product.

Oil Industry - Handy Conversion Information

* Natural gas is converted to barrels of oil equivalent using a ratio of

5,487 cubic feet of natural gas per one barrel of crude oil. This ratio is

based on the actual average equivalent energy content of TOTAL's natural gas

reserves.

1 barrel of crude oil per day = appr. 50 tons of crude oil per year

1 ton of crude oil

= 1 metric ton of crude oil

= appr. 7.3 barrels of crude oil (assuming

a specific gravity of 33 API)

= 6.6-8.0 bbl. of crude oil with 7.333 bbl.

taken as average

= 1.16 kl. of crude oil (average)

1 ton of oil equivalent

= appr. 1,125 cubic meters of natural gas
