The Jubilee oil field in Ghana, due to come online at the end of next year, should provide Anadarko Petroleum Corp. with a healthy output worth $25 a barrel.

Senior vice-president for exploration Bob Daniels said work at the Ghana oil field has so far ensured the project is being delivered on time and on budget.

The oil field, which is estimated to contain 1.8 billion barrels of oil, is mostly owned by Anadarko.
