 1 - Doba basin
The production rigs and wells
Komé field (2 to 2 rigs), Bolobo field (1 rig) and Miandoum field (1 rig)
Total of 320 production wellsThe pipeline from Doba to Kibri

Buried to the approximate depth of 1 m and deeper with reinforced walls on certain areas (crossing of rivers, ...)
Stop valves at 35 km interval monitored 24 hours a day Environmental risks
Rigs :
Explosion with oil spillage (ex: Nigeria case)
Uncontrolled flow and oil spill
Pipeline :
Leaks with impact on the groundwater table
