EOG reports roughly 60,000 acres leased in the Austin Chalk, positioned as a sweet spot in South Texas and largely leased though full delineation remains ongoing. Chalk will be integrated into core Eagle Ford development with equal capital allocation, leveraging Dorado learnings to accelerate progress and adding about one extra year of drilling inventory for the San Antonio division at current activity levels.

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 states it has identified and leased about 60,000 acres in the Austin Chalk. 1 Management further characterizes this acreage position as a “sweet spot” and says it has leased up the majority of the sweet spot, which is why it is comfortable discussing the play publicly now. 1 EOG also indicates it is still trying to figure out the extent of the sweet spot even after leasing it, suggesting the play is not fully delineated but the initial leasing phase is largely complete. 1
On the economics and early drilling confirmation, EOG reports drilling about 12 high-return wells on the leased area (as of the discussion) that confirm strong economics meeting its hurdle rates, including payouts of less than 1 year at $65 WTI and returns over 100% (as described). 1 EOG also later indicates it has drilled 20 net wells on the acquired acreage and continues to use the play as a confirmed, investable opportunity. 2
When asked how it will be integrated into capital allocation and development plans, EOG’s response frames Chalk as being placed into the mix of standard Eagle Ford and Austin Chalk proper core development in South Texas rather than treated as a separate, standalone program with radically different capital mechanics. 3
Specifically:
Additionally, EOG quantifies what the leasing/development inventory contributes to the South Texas drilling plan:
EOG describes the Austin Chalk position as geographically and geologically related to its Eagle Ford footprint:
It also provides a confirmatory development-economic comparison:
EOG reinforces the “integration” point with a second, later description:
While your question asks specifically about “South Texas versus the Eagle Ford and other legacy assets,” the excerpts provided focus on how Chalk fits inside the core Eagle Ford development framework, rather than giving a detailed relative ranking versus each legacy basin.
That said, EOG does provide two relevant framing statements:
Chalk is not treated as a separate, competing priority; it is treated as part of core Eagle Ford development economics/capital allocation. 3
Strategic/operational learnings from other divisions are used to improve Chalk execution, implying Chalk benefits from cross-division capability rather than competing with legacy assets for the same “type” of resources. 3
The excerpts do not quantify a formal capital “budget share” for Chalk versus each Eagle Ford legacy sub-area, nor do they provide a basin-by-basin capital allocation table. However, they do give a key operational integration takeaway: Chalk’s inventory is expected to be absorbed into San Antonio division drilling schedules at current activity levels, implying Chalk is intended to extend resource life within the South Texas footprint, not to divert capital away from the main Eagle Ford program. 12

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 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.

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.

Answer outline
Leasing in the Austin Chalk is largely complete within the 60,000-acre sweet spot, with ongoing data work to map the play's extent. Chalk will be feathered into South Texas development, treated as equal in capital allocation to the Eagle Ford, extending the San Antonio drilling inventory without displacing legacy assets.

Answer outline
EOG reports that the Austin Chalk leasing effort has advanced to a sizeable sweet spot (~60,000 acres) with most of the area leased, and Chalk is planned to be feathered into South Texas development in the same framework as the Eagle Ford. Remaining inventory (~125 two-mile locations) supports about one additional year of drilling at current activity, while economics—comparable to Eagle Ford—will guide Chalk’s development over the next few years, leveraging learnings from Dorado."
