Vicki Hollub
President and Chief Executive Officer at Occidental Petroleum
Thank you, Jordan, and good afternoon, everyone. I'm pleased to report on a strong start to 2024 driven by our persistent focus on operational execution. As we will detail on today's call our Oil and Gas business delivered robust production results essentially offsetting an extended third-party outage. Our Midstream and OxyChem businesses outperformed our first quarter guidance.
Today, I'll start by discussing our first quarter performance, including highlighting our Delaware appraisal success and it's contribution to Permian's Development Runway. Then I'll discuss what's on the horizon for Oxy and how these initiatives are expected to generate significant value for our shareholders. Operational excellence is fundamental to everything we do at Oxy and our capabilities were evident during the first quarter as our teams generated over $2.4 billion in operating cash flow before working capital.
Though the third-party outage in the Eastern Gulf of Mexico made it a challenging start to the year, our teams delivered excellent performance in all areas of our portfolio. We concluded the first quarter by approximating the midpoint of our production guidance and we restarted production from our Gulf of Mexico platforms affected by the outage in mid April.
Taking a closer look at our production results, the first quarter benefited from strong new well performance in the Permian Basin and Crown Rockies overcoming the impact of winter weather early in the year. In the Permian, we exceeded the midpoint of our production guidance due in part to better than expected secondary bench performance in the Delaware Basin. Our Delaware teams are achieving impressive performance by results -- performance results by applying the same proprietary subsurface workflows that have generated remarkable success in our primary benches and applying that to secondary benches. Through utilization of fit-for-purpose well-designed and reservoir characterization expertise, performance in our secondary benches is nearly matching Oxy's record setting 2023 program average. Not only that, first year cumulative production from Oxy's 2023 secondary wells exceeds the Delaware industry average for all horizontal wells for the same period by more than 30%.
We are driving financial returns for our shareholders by improving our ability to high grade our near-term inventory and by extending our runway of Tier-1 location. Meanwhile, use of our existing infrastructure yields meaningful capital efficiencies. We expect these efficiency benefits to become more impactful as secondary benches become a more substantial part of our development program. Our Rockies asset outperformed the high end of our first quarter production guidance partly driven by strong new well performance in the DJ Basin, better production uptime, higher than expected outside operating volumes. And then internationally, we achieved record gross daily production in Oman North, driven by new well performance and production uptime.
Our teams continue to improve capital efficiency through a combination of innovative well design, exceptional execution, proactive supply chain and management practices. In the DJ and Powder River basins, our teams optimized casing and submitting plans, completion stage design and profit utilization. These fit-for-purpose well design enhancements resulted in tangible first quarter well cost reductions of between $700,000 and $1 million per well compared to the first half of last year. We're also starting to see cost reduction progress in the Delaware Basin.
Our continuous drive for improvement not only leads to innovations that increased operational efficiencies, but in many instances, we're also able to reduce emission and advance progress toward our net zero goals. I'm proud of our team's involvement in another oil and gas industry first, the deployment of a fully electric well service rig. Oxy and Axis Energy Services deployed the first of its kind rig into our Permian Basin operations. Expanding electrification is integral to Oxy's strategy because it increases operational efficiency, generates cost savings, improved safety and helps reduce our emissions.
Our Midstream business significantly outperformed the high end of our guidance for the first quarter. Outperformance was partly driven by gas marketing optimization across our portfolio where our teams captured value in regional pricing disparities. Warmer than expected weather combined with various third-party Midstream infrastructure maintenance resulted in disjointed prices in some regions. Midstream's first quarter performance demonstrates how our teams realized value from these pricing abnormalities by leveraging Oxy's rich market intelligence along with our product storage and transportation portfolio.
Looking back over multiple quarters, our marketing teams have frequently demonstrated the ability to outperform with our transportation optimization capabilities playing a major role. Over the longer term, we anticipate similar marketing opportunities, but we generally exclude those opportunities from our guidance because of the difficulty in predicting event occurrence. Not only does our Midstream business provide us with full assurance for our marketed products, it also offers great diversification during periods of commodity price volatility as we saw in early 2024.
Along with being one of the top performers for the products it manufacturers, OxyChem is a consistent cash flow diversifier within our business due in part to its renowned focus and operational efficiency. During the first quarter, OxyChem benefited from improved demand from our marketed products, including PVC and vinyl chloride as well as lower ethylene cost. This performance demonstrates how our diversified asset portfolio is well positioned to deliver financial results for our shareholders throughout the commodity cycle.
In prior calls, we have reiterated our drive to increase value for our investors on an absolute and per share basis through cash flow and earnings growth. Today, I'd like to provide an update on the specific projects that we mentioned in our last quarterly call. Some aspects of the OxyChem plant enhancement projects are complete, but there is more to be done, including the battleground project where the team held a ground breaking ceremony on April 4 to kick-off the site work. Employees, contractors, community partners, city leaders and elected officials attended in support of the project. The completion of the OxyChem projects and reductions in crude oil and transportation rates from the Permian to the Gulf Coast are expected to deliver incremental cash flow of approximately $725 million per year.
In our Midstream business, we expect that ownership -- our ownership stake in Western Midstream or West will also enhance our financial results. In February, West announced an increase of over 50% in their distribution. Based on the current distribution, we anticipate that West will contribute over $240 million of additional cash flow per year to Oxy.
Additionally, we intend to increase free cash flow by repaying debt as it matures. The repayment of existing debt maturities through 2026 will result in approximately $180 million of annualized incremental cash flow from interest savings that can then be applied to further strengthen our balance sheet. Overall, we expect more than $1 billion of cash flow improvements that are independent of commodity cycles. That figure does not include our Oil and Gas business, which is also poised for continued financial success.
As most of you know, at the end of last year, we entered into an agreement to strategically enhance our Midland Basin portfolio with the acquisition of CrownRock. The free cash flow accretion and portfolio high grading to be enabled by the CrownRock acquisition are expected to provide the potential for equity appreciation and acceleration of our shareholder return priorities.
In our Low-carbon Ventures businesses, we expect to generate cash flow detached from oil and gas, price volatility and further strengthen Oxy's cash flow resiliency. The construction of our first Direct Air Capture plant, STRATOS is advancing on schedule and during the first quarter we were pleased to announce a multitude of carbon dioxide removal credit agreements with customers across a variety of sectors. Throughout Oxy's portfolio, we are focused on expanding resilient cash flow and enhancing shareholder value for decades to come.
I will now hand the call over to Sunil, who will cover our financial results and guidance.
