Résumé:
"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”"
