Stock tank barrel units.

In the worldwide oil industry an oil barrel is defined as 42 us gallons which is about 159 litres or 35 imperial gallons. Oil in place oip not to be confused with original oil in place ooip is a specialist term in petroleum geology that refers to the total oil content of an oil reservoir as this quantity cannot be measured directly it has to be estimated from other parameters measured prior to drilling or after production has begun. Stock tank barrels indicates that the cited volume is at surface conditions so it is the same unit as the generic definition of a barrel. However the industry prefers to use the stock tank barrels designation so that it is clear that the volume being cited is based on surface conditions and not reservoir conditions.

The ooip in the field was 1 6 billion stb stock tank barrels and the oil production from the field peaked at 82 000 bbl day in mid 1956 hervey and iakoakis 1991.
