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

| Calculate the volume of hydrocarbons generated by the [[source rock]], using the formula ''V'' = ''A'' × ''T'' × ''Y'' × ''M'', where:

# Estimate the proportion of the source rock that supplied hydrocarbons to the area in which the trap is located (drainage area). Use a map of the mature source rock.

*  ''V'' = potential charge volume  

# Estimate the efficiency of the migration process. For example, did 20% of the generated hydrocarbons travel from the source rock to the trap?

*  ''A'' = area  

# Calculate the volume of migrated hydrocarbons available to fill the trap

*  ''T'' = source rock thickness  

*  ''Y'' = hydrocarbon yield per volume of source from each kerogen facies and maturity class  

*  ''M'' = migration efficiency

[[:file:migration-of-petroleum_fig7-12.png|Figure 1]] is a hypothetical migration pathway map. The lower map shows the thickness of source rock, the top of the oil and gas windows, and the drainage areas for two traps labeled A and B of the same area shown in the upper map. The drainage areas for traps A and B were made using the migration pathway map.
