REQUIRD CONDITIONS FOR GEOLOGIC ACCUMULATION OF PETROLEUM ARE
i. Organic rich source rock (biogenic sediments) to generate oil and/or gas over geologic
time.
ii. Source rock burial and geothermal heating to convert organic sediment to petroleum
compounds
iii. Reservoir rock with requisite porosity and permeability to store and transfer hydrocarbon
fluids.
iv. Impermeable seal or cap rock to prevent upward escape of buoyant petroleum
compounds to the Earth’s surface.
v. Geometric arrangement of source, reservoir and seal rocks in such a way to trap
petroleum in subsurface.
vi. A temporal sequence / geologic history of trap formation and petroleum generation that
favors subsurface accumulation of petroleum
vii. Subsurface preservation of petroleum accumulation over geologic time until extraction
and production
sourse rock, migration path, reservoir rock, traps and fault blocks (cap rock base rock) sealing.
There are some conditions for accumulation of petroleum that are source rock, migration path, reservoir rock and cap rock.
