EOG reports a major Austin Chalk leasing milestone, leasing roughly 60,000 acres in a core sweet spot at favorable costs and validating strong early economics with wells showing payouts under one year at $65 WTI. Chalk is planned to feather into South Texas development within the core Eagle Ford program, not as a standalone track, and is expected to add about one additional year of drilling inventory for the San Antonio division while delineation continues.

What is the status of leasing in the Austin Chalk and how will Chalk be integrated into development plans in South Texas versus the Eagle Ford and other legacy assets?
EOG reports that it identified and leased about 60,000 acres in the Austin Chalk and characterizes this as a “sweet spot.” 1
Management indicates that it has leased up the majority of the sweet spot, which is why EOG is now willing to discuss the play publicly. 1
EOG also provides how it sourced the position: mostly organic leasing with some small acquisitions at an average cost of ~$1,200 per acre. 1
EOG reports about a dozen wells drilled to date that confirm strong economics and meet hurdle rates, including payouts of less than 1 year at $65 WTI and returns over 100% (as described for the wells drilled in the Austin Chalk leased area). 1
EOG further states it has drilled 20 net wells on the acquired acreage, again noting less than 1-year payouts at $65 WTI. 2
In response to a question about capital allocation and how Chalk would be “feathered” into development plans, EOG frames Chalk as being integrated alongside its core Eagle Ford development. 34
Management says Chalk and its capital allocation will be “equally within our core Eagle Ford development” and that, because the resource sits in a sweet spot and is geologically positioned southeast of Eastern Eagle Ford acreage, it will be “pretty much in the mix” of standard Eagle Ford and Austin Chalk proper core development over the “next handful of years.” 41
EOG quantifies the forward inventory contribution from the leased Chalk sweet spot: it has identified ~125 remaining 2-mile lateral locations in the ~60,000-acre sweet spot. 1
EOG says this adds about 1 additional full year of drilling inventory to its San Antonio division at current pace. 1
EOG also reinforces that it is still gathering data and evaluating the extent of the sweet spot (i.e., leasing and full delineation are not necessarily fully “finished,” but the majority of the sweet spot position is secured). 2
EOG explains that integration is not only capital allocation but also technical execution: moving “down south” into Chalk, it has had to apply high-temperature/high-pressure learnings (from Dorado) to push development forward. 4
EOG also describes the Austin Chalk resource behavior as more down-dip and deeper/mature than Eagle Ford, tending to be a combo play with more associated gas, while still delivering total liquids yields comparable to Eagle Ford proper. 1
EOG’s framing is that Chalk is being treated as an extension/add-on to Eagle Ford development rather than as a wholly separate “legacy replacement” initiative. Specifically:
In other words, based on the excerpts, EOG is not signaling that Chalk will divert the core Eagle Ford plan into a separate project structure; rather, it is being folded into Eagle Ford execution culture and scheduling, leveraging existing operational know-how. 34
When asked whether EOG is “done leasing” because it is willing to discuss the play, management’s answer trajectory is:
So, the status is best characterized as:
All of the above is consistent with EOG’s stated goal of leveraging decentralization and technical expertise to extend resource life and improve returns profile across divisions using analogous play learning. 4

Management describes EOG’s decentralized exploration as division-driven, organic, and data-driven, with divisions identifying opportunities and applying shared technical capabilities to boost asset quality and returns. The approach balances a domestic emphasis with selective international opportunities, emphasizes risk-adjusted decision-making, and relies on rapid, decisive execution across plays and basins. It also highlights cross-divisional knowledge sharing to upgrade portfolio quality rather than simply expand resource counts.

Answer outline
EOG has largely leased the Austin Chalk sweet spot (~60,000 acres) and plans to feather Chalk into its South Texas Eagle Ford program, treating it as a core extension rather than a standalone capital project. The move adds about 125 remaining 2-mile locations and roughly one more year of drilling inventory, with economics similar to Eagle Ford and cross‑basin learnings guiding execution.

Answer outline
EOG indicates about 60,000 acres leased in the Austin Chalk, with management signaling the majority of the ‘sweet spot’ is captured and Chalk will be feathered into South Texas development. The play will sit alongside core Eagle Ford in capital allocation, delivering comparable liquids yields and adding roughly one extra year of drilling inventory for the San Antonio division.

EOG Resources reports the Austin Chalk leasing has reached roughly 60,000 acres, with the majority secured and ready for development. The company plans to weave Chalk into its core South Texas Eagle Ford program, treating it as an extension rather than a standalone target, while preserving similar liquids economics and adding roughly one additional year of drilling inventory for the San Antonio division.
