Remediation by Enhanced Natural Attenuation (RENA)

The search for crude oil has expanded in many parts of the world with positive results in some members of the Organization of the Petroleum Exporting Countries (OPEC). Regardless of the numerous socio-economic gains from the discovery of crude oil, spills sometimes occur during production operations, or due to accidental discharges, leakages from corroded bunkers and transport vessels, and human errors. These spills contaminate the surrounding environment and negatively affect the ecosystem (Ajagbe et al., 2012; Khamehchiyan et al., 2007).
