Accumulation

A trap may or may not contain oil or gas. Accumulations, or pools, are traps that contain oil or gas.[1]

A hydrocarbon accumulation forms when migrating hydrocarbon filaments encounter a zone (the seal), either laterally or vertically, with pore throat sizes smaller than the carrier bed. The seal pore throat breakthrough pressure or the distance to the spill point of the trap, whichever is less, determines the hydrocarbon accumulation column height.[2]
