The company said its 2020 exploration and production capital and exploratory budget will be $3 billion, higher than the estimated $2.7 billion allocated for 2019.
The company said it would allocate $1.69 billion for production, $860 million for offshore Guyana developments and $450 million for exploration and appraisal activities.
Hess has been relying on its investment in offshore Guyana, one of the world's most important oil and gas blocks in the last decade, which is being developed by a consortium led by oil major Exxon Mobil Corp.
The partnership recently boosted Guyana oil estimates by 2 billion barrels, bringing total recoverable oil and gas resources to more than 8 billion barrels.
The company expects net production, excluding Libya, to average between 330,000 and 335,000 barrels of oil equivalent per day (boe/d) in 2020 compared with the 285,000 boe/d it expects for 2019.
"We are well positioned to deliver industry leading cash flow growth while also achieving significant reductions in our unit costs, which will drive margin expansion and lower our breakeven oil price to below $40 per barrel Brent by 2025," said Chief Executive Officer John Hess in a statement.
Hess is expected to report its fourth-quarter results and its spending in 2019, on Wednesday.
