2. Government revenue: Government obtains revenue from petroleum taxes, royalties, rents and export sales.
3. Employment: It provides direct and indirect employment in exploration, drilling, refining, transport, marketing and related services.
4. Industrial raw material and energy: Petroleum provides fuel for transport and industries and raw materials for petrochemical, fertiliser, plastic and allied industries.
5. Infrastructure and urban growth: Oil revenue finances roads, schools, hospitals, ports, pipelines and other public facilities, while oil activities encourage the growth of towns such as Port Harcourt and Warri.
