Thanks, Ryan. Diving into second quarter performance, we generated $1.84 per share in adjusted earnings. We recognize that this result was below consensus, which we primarily attribute to transitory price capture headwinds in Lower 48 natural gas and Alaska crude. Now based on strip pricing for the second half, we expect price capture to normalize and be consistent with our previous full year guidance of $22 billion in CFO at $80 WTI and our published full year sensitivities. Moving to production. We set another record in the second quarter, producing 1,805,000 barrels of oil equivalent per day, representing 6% underlying year-over-year growth with solid execution across the entire portfolio.
Planned turnarounds were successfully completed in Norway and Qatar. And Lower 48 production was also a record, averaging 1,063,000 barrels of oil equivalent per day, including 709,000 from the Permian, 235,000 from the Eagle Ford and 104,000 from the Bakken. Lower 48 underlying production grew 8% year-on-year with new wells online and strong well performance relative to our expectations across our asset base. Moving to cash flows. Second quarter CFO was $4.7 billion at an average WTI price of $74 per barrel. This includes APLNG distributions of $405 million. And in the second quarter, we also received $200 million in proceeds, primarily related to a prior year disposition.
Second quarter capital expenditures were $2.9 billion, which included $624 million for long-cycle projects. Now through the first half, we have now funded $700 million for Port Arthur LNG of the planned $1.1 billion for the year, which we expect to lead to a step-down in overall capital in the second half. We also expect to see a step-down in Lower 48 capital in the second half of the year. And as a result, we have narrowed our full year capital guidance range to $10.8 billion to $11.2 billion with no change to the midpoint. Regarding returns of capital, we returned $2.7 billion to shareholders in the second quarter. This was via $1.3 billion in share buybacks and $1.4 billion in ordinary dividends and VROC payments.
And we announced a fourth quarter VROC of $0.60 per share, which has us on track to deliver our $11 billion target for total return of capital in 2023. Turning to guidance. We forecast third quarter production to be in the range of 1.78 million to 1.82 million barrels of oil equivalent per day, which includes 20,000 barrels a day of planned seasonal turnarounds, primarily in Alaska and Europe. We have also increased the midpoint of our full year production guidance. Our new full year range is 1.8 million to 1.81 million barrels of oil equivalent per day, up 15,000 barrels per day from the prior midpoint of 1.78 million to 1.8 million previously. For APLNG, we expect distributions of $400 million in the third quarter and $1.9 billion for the full year.
Consistent with our higher production guidance for the year, we have raised our full year adjusted operating cost and our DD&A guidance by $100 million each to $8.3 billion and $8.2 billion, respectively. We have also lowered our corporate cost guidance by $100 million to $800 million due to higher interest income. And finally, as a reminder, all guidance excludes any impact from announced but not closed acquisitions such as Surmont and APLNG. So to wrap up, we had another solid operational quarter. We're confident in our outlook, leading to our increase in full year production guidance. We continue to progress our strategic initiatives across the portfolio. And we expect to return $11 billion to shareholders this year. Now that concludes our prepared remarks.
I'll turn it back over to the operator to start the Q&A.
