Mark Lashier
Chairman and Chief Executive Officer at Phillips 66
Thanks, Jeff. Welcome, everyone, to our second quarter earnings call.
First, I'd like to introduce Don Baldridge, our new EVP of Midstream and Chemicals. He previously served as the Interim CEO of DCP, and brings a wealth of midstream experience to Phillips 66. I also want to wish Tim Roberts the best in his retirement, and thank him for his contributions to Phillips 66, including being instrumental in executing our NGL wellhead-to-market strategy.
Let's turn to our second quarter performance. We continue to systematically execute on our strategic priorities, focusing on what we control. The improvements are visible in our results. Since July 2022, we've returned over $11 billion to shareholders through share repurchases and dividends. We expect to achieve our $13 billion to $15 billion target by the end of the year. Share repurchases will continue to be a priority in our capital allocation plan. We are committed to returning over 50% of our operating cash flows to shareholders.
In refining, we're enhancing performance and reducing our cost structure. Crude utilization during the quarter was our highest at over -- in over five years at 98% and clean product yield was 86%. In addition, we've lowered our costs by nearly $1 per barrel. In Midstream, we continue to benefit from synergy capture as we execute on our NGL wellhead-to-market strategy. Earlier this month, we closed on our acquisition of Pinnacle Midstream. It was a bolt-on to our natural gas gathering and processing business and grows our stable earnings with high-quality 100% fee-based long-term contracts. The assets are strategically located near our existing Permian footprint in the liquids-rich Midland Basin.
In the second quarter, we sold our 25% non-operated interest in the Rockies Express Pipeline for $685 million. We generated over $1 billion from asset dispositions toward our previously announced target of more than $3 billion. By the end of the second quarter, the Rodeo Renewable Energy Complex reached full rates with the startup of the second hydrocracker in both pre-treatment units. The complex is processing approximately 50,000 barrels per day of renewable feedstocks. On the next two slides, I'll focus on the improvements we've made to our cost structure. We're approaching our $1.4 billion run rate savings target and the results are hitting the bottom line.
Slide 4 provides cost detail at the total company level compared with the first half of 2022. We've supported growing our business while mitigating inflationary impacts through business transformation. We've realized approximately $400 million in cost reductions, including our share of WRB costs. Additionally, we've been successful in driving efficiencies in our logistics spend that flow-through margin, as well as lowering our sustaining capital spend.
Slide 5 highlights how our business transformation efforts have translated into a lower refining cost per barrel. Adjusted controllable costs, excluding turnarounds were $5.93 per barrel. We're closing in on our target to lower cost by $1 per barrel. We continue to increase shareholder value through strong operating performance and disciplined capital allocation as we deliver on our strategic priorities. I want to recognize our employees for their hard work and dedication to driving value creation for shareholders.
Kevin, over to you.
