Key facts
  • The length of this pipeline - 829 km

WREP facilities include:

  • Six pump stations (three in Azerbaijan, three in Georgia)
  • Two pressure reduction stations located in Georgia
  • 59 block valves with check valves along the pipeline
  • One intermediate pigging station in Azerbaijan and one at each station.

The Western Route Export Pipeline (WREP) transports crude oil from offshore oil fields in the Caspian Sea to the Black Sea, from where the crude is further shipped via tankers through the Bosporus to European markets.


The pipeline begins at the Sangachal terminal near Baku and travels through Azerbaijan and Georgia to the Supsa terminal on the Georgian coast of the Black Sea. The length of this pipeline is 829 km.


The Azerbaijan International Operating Company (AIOC) owns and operates the pipeline on behalf of the ACG PSA Parties.


Construction started following the ratification of the intergovernmental agreement between Azerbaijan and Georgia in April 1996 and was completed in November 1998. WREP has been in operation since February 1999. In April 17, 1999 the Supsa terminal was inaugurated. A full re-commissioning programme for WREP was undertaken in 2008.


Throughout 2007 WREP was shutdown to permit an extensive repair and replacement work to take place. The programme included section replacements in Georgia and Azerbaijan. The work was completed in the first quarter of 2008. During the shutdown other routes were used to deliver oil to world markets, so ensuring there was no impact on demand or ACG production.


During the first six months of 2023, the Sangachal terminal exported around 1 million barrels through the Western Route Export Pipeline (WREP).
