PREREQUISITES FOR HYDROCARBON ACCUMULATION

The accumulation of hydrocarbons and formation of oil or gas deposit involve certain prerequisites. These are the following:

1. Source Rock
2. Reservoir Rock
3. Trap
4. Seal
5. Timing
6. Migration

Not all petroleum discoveries, however, are commercial or economic – that is they can all be developed and produced at a profit. Additional geological requirements for a petroleum deposit to be economic are:

1. Sufficient volume of accumulated hydrocarbon – in-place reserves
2. Producibility – recoverable reserves
   1. adequate reservoir drive
   2. concentration
   3. oil quality (e.g., API gravity or viscosity)
3. Preservation of the petroleum deposit, that is freedom from:
   1. flushing
   2. biodegradation
   3. diffusion
   4. overcooking

Non-geological factors affecting profitability of a petroleum discovery are:

• Cost of development and production
• Price of oil/gas
• Fiscal terms

Source Rock

— Sedimentary rock containing organic material, which under heat, time, and pressure was transformed to liquid or gaseous hydrocarbons. Source rock is usually shale or limestone.

Some explorationists use a stricter definition — that is requiring sufficient hydrocarbon generation and migration from the rock unit to form commercial accumulation(s) of oil and/or gas for it to be considered a source rock.

Possible source rock

— any unit of rock, which by its general lithology and depositional environment, may generate hydrocarbons.
