EOG indicates it has leased the majority of the Austin Chalk sweet spot (~60,000 acres) and plans to feather Chalk into its South Texas Eagle Ford program. Chalk is treated as a parallel development rather than a standalone engine. This integration approach preserves Eagle Ford as the core development framework while adding Chalk as a high-potential extension.

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’s update indicates it has already leased most of the “sweet spot” acreage it intends to pursue right now, rather than being at the beginning of a long leasing phase. Specifically, management said it identified and leased about 60,000 acres in the Austin Chalk 1 and believes it has leased up the majority of the sweet spot, which is why it could start discussing it publicly 1.
On the practical inventory side, EOG quantified the drilling impact of that leasing: within its identified ~60,000-acre sweet spot, it has about 125 remaining 2-mile locations, which adds ~1 additional full year of drilling inventory to its San Antonio division at current pace 1. Management also stated that the company continues to gather data and evaluate extent, indicating leasing may not be strictly “done forever,” but near-term development readiness is already established by the current acreage position 2.
EOG frames the Austin Chalk as an extension/addition to its South Texas development program rather than a totally separate development engine. For capital allocation and program structure, management said Chalk will be “pretty much in the mix of our standard Eagle Ford” development, while also noting that the core Eagle Ford proper will be developed over the “next handful of years” 3.
This suggests Chalk is being treated as a parallel resource opportunity fed into the same operational/capital framework as the Eagle Ford, not as a distant, independently timed project.
EOG links Chalk integration to (a) locating a high-return sweet spot and (b) applying operational learnings from other basins—especially because Chalk sits southeast of the Eastern Eagle Ford acreage 1 and trends more down-dip, deeper/more mature with more associated gas, making it a “combo play” while maintaining total liquids yields comparable to Eagle Ford proper 1.
Management emphasized that the company used its regional geologic/reservoir understanding to identify the Chalk extension and that the wells have met its hurdle rates, with payouts of less than 1 year at $65 WTI and returns over 100% on drilled wells 1. It also emphasized leveraging high-temperature, high-pressure operations from Dorado and applying “a lot of our learnings” to push it forward 3, reinforcing that Chalk development is being integrated through established technical capability rather than waiting for new infrastructure or a fresh operating model.
EOG states it has already drilled a meaningful number of wells and that results support economics and speed-to-payback:
That progression (leasing → initial well results → expanding inventory discussion) is consistent with a plan to feather Chalk into an active development schedule rather than remain in a long appraisal-only posture.
EOG was directly asked whether it is essentially “done leasing” and how it thinks about capital allocation in South Texas based on Chalk relative to the structural elements and legacy foundation in the Eagle Ford. Management’s answer was essentially that Chalk will be equally within the core Eagle Ford development for allocation purposes, because both are within a sweet spot view: it will be “equally within our core Eagle Ford development” 3.
In other words, EOG does not describe Chalk as competing for capital in a “winner-take-all” way against Eagle Ford’s existing legacy platform; rather, it describes Chalk as another resource opportunity being folded into the same ongoing Eagle Ford proper development cadence 3.
While Chalk is treated as part of the Eagle Ford development plan for capital purposes, EOG highlights key differences that may affect execution details:
This combination—comparable liquids economics plus differences mainly in maturity/fluid mix—helps explain why EOG can integrate Chalk into Eagle Ford plans without treating it as fundamentally alien. The “feathering” is about adding drilling locations to the program and using transferable operational strengths, while still learning the nuances (“continue to gather data and evaluate its extent”) 2.

EOG indicates the Austin Chalk leasing is largely complete, with about 60,000 acres leased and strong early-well economics underpinning the position. Chalk will be woven into South Texas development as an extension of the core Eagle Ford program, with capital allocation and cross-basin operational learnings guiding its integration rather than a separate, stand-alone plan.

Answer outline
EOG reports that roughly 60,000 acres in the Austin Chalk have been leased in a defined sweet spot and that Chalk will be balanced within core Eagle Ford development in South Texas over the next several years. The play shows compelling economics—a payout in under one year at $65 WTI and returns over 100%—with about 125 remaining two-mile lateral locations expanding inventory. Chalk integration leverages cross-basin learnings and decentralization to extend drilling runway.

Answer outline
EOG reports substantial progress in Austin Chalk leasing, with about 60,000 acres in the Chalk sweet spot largely secured and ongoing delineation to define boundaries. Chalk is being integrated into South Texas development as a mix with the Eagle Ford core, supported by attractive economics (sub-1-year payout at $65 WTI and >100% returns) and a remaining inventory that extends roughly one year of drilling for the San Antonio division.
