DORIS optimized the Pre-Project Dossier


This plant is fed by 14 gas producing wells drilled before plant start-up and 23 extra wells drilled later. The gas is collected via 5 clusters, provided with production and test manifolds, and sent through trunklines to the Central Processing Facility to be treated.
The CO2 content in the raw gas (7%) is eliminated through an amine unit and re-injected in 2 disposal wells.
Treated gas is exported through a 24’’ pipeline up to a tie-in point to a new pipeline to be installed as part of another project.
