==Composition of early vs. later generation==
==Composition of early vs. later generation==
Early generation concentrates light products into large pores and fracture networks. Thus, the oil expelled is lighter in composition than the oil retained. However, as maturity continues, the difference between these two disappears and oil–source correlation improves.
Early generation concentrates light products into large [[Pore system fundamentals|pores]] and [[fracture networks]]. Thus, the oil expelled is lighter in [[Oil and condensate analysis|composition]] than the oil retained. However, as maturity continues, the difference between these two disappears and [[Oil-oil and oil-source rock correlation|oil–source correlation]] improves.
