Exxon and CNOOC Ltd (0883.HK) , opens new tab filed arbitration claims claiming a pre-emption right to any sale of Hess’ lucrative stake in a Guyana oil-producing joint venture. The challenge threatens to block Chevron’s biggest deal since its 2001 acquisition of Texaco for $36 billion.

Exxon and CNOOC have argued Chevron's bid for Hess triggered a right of first refusal clause in their Guyana joint operating agreement. Chevron and Hess dispute that claim.
