"Niveaux de contamination par les Eléments Traces Métalliques (Cd, Pb, Cu et Zn) de l’eau de production et des sédiments des champs pétroliers du complexe G.E.A – Hassi Messaoud"

Abstract

"The actual work aims to provide management team with decision making tools in order to implement continual improvement of the Environmental Management Plan compounds. Development of those tools was carried out by environmental risks analysis related to Trace Metals (Cd, Pb, Cu and Zn) within the actual produced water management practices in GEA at Hassi Messaoud. Trace metals concentrations measured in produced water and related sediments has confirmed the hazard assumed at the beginning. Risk analysis was carried by “Bow Tie” methodology and was performed on the identified Top Event. Risk rating was carried, using the company Qualitative Risk Matrix, and has classified the top event as High risk, which means that implementing proactive barriers becomes mandatory. Short and medium term actions were proposed and further risk analysis was recommended for other events related to the hazard “Trace metals in produced water effluent”"
