Oil and Gas Minister Sauat Mynbayev said state oil and gas company KazMunaiGas would borrow $1 billion over three years from the consortium partners to pay for the stake, at the London Interbank Offered Rate plus 3%, Reuters reported.
"KMG will service and repay this debt with the cash flow that its 10% stake will generate," Mynbayev said.
The Karachaganak consortium is led by Britain's BG Group and Italy's Eni.
