PETROLEUM SYSTEM ( Characteristic Of Elements) :<3:
SEAL ( CAP ROCK )
Common shale layer or evaporites
Upward migration
Impermeable ductile stratum
Permeability
Lateral extent and continuity
Thickness
RESERVOIR
:<3:
Typical layer of sandstone or limestone
Could be fracture stratum of impermeable rock
A porous and permeable material
TRAP
Concave downward geometric arrangement of seal
Impermeable lateral equivalents of reservoir rock
Self trapped
common anticline or stratigraphic pinchout
Types
Structural Trap
Anticlinal Trap
oil that find has been bent
often found adjacent to mountain ranges
Fault Trap
movement along fault line
Stratigraphic Trap
Variation in lithology or stratigraphy
facies change, variable porosity and permeability
Differential Entrapment
can be different structural relationship.
free gas can be able to form
