Executive Vice President and Chief Financial Officer at ConocoPhillips
Thanks, Ryan. Starting with fourth quarter results, we generated $2.71 in adjusted earnings per share. Fourth quarter production was 1,758,000 barrels oil equivalent per day, which included a 27,000-barrel-a-day negative impact from weather in the Lower 48. Lower 48 production averaged 997,000, including 671,000 from the Permian, 214,000 from the Eagle Ford, and 96,000 from the Bakken.
Moving to cash flow, fourth quarter CFO was $6.5 billion excluding working capital at an average WTI price of $83 per barrel. APLNG distributions were $639 million and fourth quarter capital expenditures were $2.5 billion, including $2.1 billion of base capital and $300 million for acquisitions and North Field East payments.
On capital allocation, we returned $5.1 billion to shareholders through ordinary dividends, VROC payments, and share buybacks, while also reducing gross debt by $400 million. Full year CFO was $28.5 billion, excluding working capital at an average WTI price of $94 per barrel in 2022. Full year APLNG distributions were $2.2 billion and full year total capex was $10.2 billion, with base capex achieving our guidance of $8.1 billion, and $2.1 billion of acquisitions in North Field East payments. Full year return of capital was $15 billion while $3.4 billion went to debt reduction, with cash and short-term investments ending the year at $9.5 billion.
Turning to 2023 guidance. We forecast full year production will be in a range of 1.76 million to 1.8 million barrels of oil equivalent per day, which represents 1% to 4% of organic growth. Our first quarter production guidance range is 1.72 million to 1.76 million, which includes 35,000 of plant maintenance, primarily in Qatar and the Lower 48. Our full year plant maintenance is expected to be similar to 2022.
On capital spending, we expect a range of $10.7 billion to $11.3 billion, which I will discuss in more detail in a moment. We expect operating cost of $8.2 billion, DD&A of $8.1 billion, and corporate segment net loss of $900 million. For 2023 cash flow, we forecast $22 billion in CFO at $80 a barrel WTI, $85 Brent, and $325 Henry Hub at current strip prices for regional differentials. Included in our cash flow forecast is $1.9 billion in APLNG distributions with $600 million expected in the first quarter.
Now regarding capex. We provided waterfall in our prepared materials bridging 2022 actual spending to 2023 guidance. Starting with base capital spending, we forecast an increase from $8.1 billion in 2022 to a range of $9.1 billion to $9.3 billion in 2023. The remaining $1.6 billion to $2.0 billion is allocated to longer-term projects. Of this amount, $1.5 billion to $1.6 billion is for LNG projects, which includes Port Arthur, North Field East, and North Field South.
For Port Arthur specifically, after factoring in expected project financing, we forecast that ConocoPhillips' net investment will be just under $2 billion over the five-year investment period. However, more than half of this capital investment will be in 2023. For Willow, we're guiding to $100 million to $400 million of incremental spending with the higher end of this range assuming that the project is sanctioned this year.
In summary, we're happy with our strong 2022 results, which would not be possible without the hard work and dedication of our talented workforce. And we are well-positioned to balance investing in our deep and diversified portfolio this year while also continuing to return capital to our shareholders.
That concludes our prepared remarks. I'll now turn the call back over to Phil.
