Talos finalises Zama unitisation deal with Pemex

US producer Talos Energy has finalised the unitisation agreement for its shallow-water Zama discovery in Mexico following an operatorship dispute with state-owned Pemex. In 2017, Talos announced the Zama find of up to 950mn bl of recoverable oil equivalent in block 7, which neighbours Pemex acreage. But after more than two years of talks, the parties failed to agree and the energy ministry designated Pemex as operator in July last year. That decision was criticised for deterring investors, for the strain it will put on Pemex's stretched finances, and because of Pemex's lack of experience drilling a reservoir at Zama's depth. The block could produce up to 160,000 b/d of oil equivalent, Talos says, making it the largest exploration and production contract awarded since 2014's energy reforms.
