A [[cross-sealing fault]] allows fill below the JLLP and possibly as deep as the SSP. A trap also may be partially filled (PF) due to either charge or top seal capacity. A partially filled trap can have a [[Fluid contacts|hydrocarbon contact]] at any depth. | A [[cross-sealing fault]] allows fill below the JLLP and possibly as deep as the SSP.
