Billy Helms
President & Chief Operating Officer at EOG Resources
Thanks, Tim. I would like to first thank our employees for their commitment and dedication that led to another quarter of exceptional execution. EOG once again beat our forecasted target and delivered a near-perfect quarter. As a result, we have completed the first half of the year ahead on volumes and ahead on totaled per unit cash operating cost.
Our volume performance in the first half of the year is due to several factors. The performance of new wells is outpacing our forecast, primarily in the Delaware Basin, part of which is due to our new completion design. We were also experiencing less downtime due to market interruptions than previously planned. Our investments in infrastructure along with real-time data analytics, provided the control and flexibility needed to redirect sales volumes to different markets to maintain production.
Unit cash operating costs for the first half of the year averaged 5% below the midpoints of our quarterly guidance, due to a combination of several factors including lower lease operating expenses, as well as reduced transportation costs. Lower workover and compression-related expense reduced LOE, while transportation costs benefited from the flexibility to sell into more favorable markets throughout the quarter. Credit goes to the cross-functional efforts of our production, marketing and information systems teams who remain focused on sustainable low-cost operations quarter-after-quarter. We have line-of-sight to maintain these cost improvements throughout the year and as a result have reduced our full year guidance for total unit cash operating cost.
Operationally, EOG is firing on all cylinders. Our foundational Eagle Ford and Delaware Basin plays are delivering exceptional results, while our emerging plays benefited from learnings and technology transfer across our multi-basin portfolio. Our decentralized structure supports innovation in each operating area which function much like independent technology incubators and compounds the impact of that innovation by taking ideas borne in one area and expanding them across multiple basins and across multiple functions.
Across every operating area, our frontline engineers and geologists work that technology every day to lower cost and improve well performance. We look for strategic opportunities to vertically integrate certain services within the supply chain, where we find an opportunity to better align those services with our goals. That includes areas like downhole drilling motors, drilling mud, sand and water. Developing search capabilities in-house, significantly improves the cost structure of the company.
This quarter, we're highlighting drilling performance improvements in the South Texas Dorado, South Powder River Basin, Mowry and the Ohio Utica Combo plays. Our emerging plays are moving up the learning curve faster due to the benefit of drilling advancements and the application of technology over the past decade.
We've continued to evolve our proprietary suite of applications powered by real-time high-frequency data and analytics to assist our frontline employees to collaborate and make decisions faster. The combined benefit of these efforts has already contributed to an increase of up to 25% in drilling feet per day for wells in our emerging plays this year. In our Ohio Utica play, we recently drilled a 15,700 foot lateral in 2.6 days and 100% in-zone.
Capital expenditures for the first half were also running light due primarily to infrastructure spend that has been deferred into the second half of the year. It is worth noting the economic impact of our investments in EOG-owned infrastructure. Our realized U.S. oil price in the second quarter was $1.23 above WTI, and U.S. natural gas was essentially flat to Henry Hub. Capex for our drilling and completion program are right on track. The rate of change for inflation this year is consistent with what we had anticipated at the start of the year.
So we still see line-of-sight to limit year-over-year well cost inflation in '23 to just 10%. While any additional softening of service costs this year has the potential to impact 2024, it's simply too early to predict. The market remains too dynamic, particularly given the constructive outlook for oil in the second half of the year.
Furthermore, we remain focused on generating long-term, sustainable cost reductions, driven by utilizing the highest-quality equipment and the highest-performing teams which are less exposed to the leading-edge price declines that we see in more marginal equipment. Our $6 billion capital program is focused -- is forecasted to deliver 3% oil volume growth and 6% total liquids growth.
In Dorado, our South Texas natural gas play, we delayed the timing of planned completions earlier this year and about five wells have been pushed into early 2024. Thus, we reduced our full year gas volume guidance accordingly. We maintained our drilling pace in Dorado to build operational momentum and capture the corresponding efficiencies. As a result, we are seeing a 16% improvement in our drilling times for Dorado as shown on Slide 11 of our updated Investor Presentation.
We are constructive on natural gas longer-term and believe Dorado will be one of the lowest-cost and lowest emission supplies of natural gas in the U.S., and will compete on a global scale. This year has started out with many challenges, but also many opportunities to continue to improve the company. I'm very pleased with the progress our teams continue to deliver and remain optimistic about the second half of the year and how the company is positioned for the future.
Now I'll turn the call over to Ken to discuss progress on lowering our emissions.
