Kashagan Arbitration: Tribunal Rejects $12 Billion in Kazakhstan’s Claims
An arbitration tribunal rejected $12B of Kazakhstan's claims against Kashagan oil field investors, citing late filings. The case involves $20B in disputed costs. Investors include ExxonMobil, Shell, and TotalEnergies. Kazakhstan alleges inflated costs and bribery, while NCOC denies wrongdoing. Separately, Kazakhstan seeks a $5.2B environmental fine from the operator. Proceedings may continue until 2028.
