Azerbaijan's State Oil Company (SOCAR) is lining up a final investment decision by the end of 2026 on a petrochemical expansion in Türkiye valued at up to $7 billion, according to reporting published on 16 September. The project would deepen a position in which SOCAR has already invested a cumulative $19.5 billion in the Turkish market.
The company has finished preliminary engineering work and is moving into the full front-end engineering design (FEED) phase. It has signed a memorandum with engineering firm Technip for technical and economic studies. Kanan Mirzayev, cited in the report, put the investment at between $5 billion and $7 billion, so the final figure remains open until FEED is complete.
SOCAR's Turkish footprint centres on two assets: the Petkim petrochemical complex, with annual capacity of 3.6 million tonnes, and the STAR Refinery, which can process 13 million tonnes of crude a year. The expansion is pitched as a push into higher-value manufacturing, with potential to cut Türkiye's polyethylene imports by about $1.5 billion.
The scale of the plan sits against a Fitch Ratings assessment dated 15 September. Fitch expects SOCAR to invest around AZN 4 billion annually across 2026-2030. Key figures from the agency:
Fitch also expects the decline in SOCAR's production to stabilise from 2028.
Crude prices remain elevated. Azeri Light (CIF) averaged $121.75 a barrel in the week of 28 September to 2 October, up 0.6% on the week, while Dated Brent averaged $123.52, according to Trend's weekly review.
For investors, the sequence matters: FEED will define cost, partners and financing, and the year-end decision will show how SOCAR balances a multi-billion-dollar downstream bet against Fitch's projected rise in leverage. Higher-margin petrochemicals would diversify earnings beyond crude and gas sales, but no financing structure has been disclosed.
