Anadarko plans to sell up to $3 billion of assets this year as it aims to offset the effects of the oil price crash.
The US oil giant has already closed or signed agreements to monetize about $1.3billion of assets this year, it said last week.
Oil companies are selling assets in response to a more than 70 percent fall in crude oil prices that has made drilling uneconomical.
Anadarko lowered its total sales volumes forecast, excluding a pending divestiture, to 770,000-781,000 barrels of oil equivalent per day (boe/d) compared with 836,000 boe/d in 2015.
The company said it expected 2016 capital expenditures to range between $2.6billion and $2.8billion, compared with its previous estimate of $2.8billion.
The company said it cut its US onshore rig count by 80% to five operated rigs, from an average of 25 in 2015.
Anadarko had slashed its quarterly dividend by 82% to 5 cents earlier this month in an attempt to preserve cash.
President and chief executive Al Walker said: “In 2016, we will continue our disciplined and focused approach, preserving and building value by leveraging our best-in-class capital allocation, enhancing operational efficiencies and continuing an active monetization program.”
