- Oil drilling projects are capital intensive ventures undertaken by exploration and production companies.
- The oil is usually found in geologic formations deep within the earth crust.
- To access this fuel, large drilling ventures must be undertaken in order to accommodate to technology and man power.
- New areas have to cleared and this can push the habitat of organisms backward
