Irri flowstation is a new gathering station, located in the Irri/Isoko area, designed to receive well-fluids from 3 existing and 2 future dual-completion wells.

The Plant is designed to export 120 MMSCFD of gas and 15,700 BPD of oil from 3 existing wells, rising to 160 MMSCFD of gas and 23,000 BPD of oil when the future wells are brought online.

The gas is treated to reduce the CO2 content to bellow 2 mol% before it is exported to Kwale via an 18” pipeline. In the event of an upset at Kwale or there being no demand for the gas from Irri, the oil production may be continued by venting the gas stream to flare
