The composition of hydrocarbons expelled from a [[source rock]] is a primary control on the composition of reservoired hydrocarbons. In general, the larger-molecular-weight compounds are preferentially retained in the source rock while the smaller compounds are expelled.
The [[Oil and condensate analysis|composition of hydrocarbons]] expelled from a [[source rock]] is a primary control on the composition of reservoired hydrocarbons. In general, the larger-molecular-weight compounds are preferentially retained in the source rock while the smaller compounds are expelled.
