The size of a petroleum system includes the total volume of all recoverable hydrocarbons that originated from a single pod of active source rock. This total volume is used to compare against other petroleum systems and to determine the generation–accumulation efficiency.
Volume of petroleum
The discovered hydrocarbons include shows, seeps, and accumulations of oil and gas. The size of a petroleum system is determined using a table such as the following for the fields in the Deer-Boar(.) system, with reserves of approximately 1.2 billion barrels (bblbarrels).
|Field Name||Discovery Date||Reservoir Rock||API Gravity (°APIAmerican Petroleum Institute)||Cum. Oil Production (x106 bblbarrels)||Remaining Reserves (x106 bblbarrels)|
|Big Oil||1954||Boar Ss||32||310||90|
Generation–accumulation efficiency is the ratio (expressed as a percentage) of the total volume of trapped (in-place) petroleum in the petroleum system to the total volume of petroleum generated from the pod of active source rock.
