(a) The porosity against permeability; (b) schematic overview of compactional evolution for high soft component sandstones; (c) schematic overview of oil emplacement happened during diagenesis for low soft component sandstones with continual oil emplacement. LPoHPe: low porosity and high permeability samples; HPoLPe: high porosity and low permeability samples.
