The table below lists a procedure for estimating the volume of migrated hydrocarbons available to fill a trap.
The table below lists a procedure for estimating the volume of migrated hydrocarbons available to fill a trap.
# Calculate the volume of hydrocarbons generated by the [[source rock]], using the formula <math>\text{V} = \text{A} \times \text{T} \times \text{Y} \times \text{M}</math>, where:
#* ''V'' = potential charge volume
#* ''A'' = area
#* ''T'' = source rock thickness
#* ''Y'' = hydrocarbon yield per volume of source from each kerogen facies and maturity class
#* ''M'' = migration efficiency
