EOG Signals Austin Chalk Leasing Largely Leased, Integrated with Eagle Ford in Q2 2026

Status of Austin Chalk leasing and how it will be integrated vs. Eagle Ford and other legacy assets (EOG)

1) Leasing status in the Austin Chalk (what’s been done)

EOG reports that it identified and leased about 60,000 acres in the Austin Chalk, describing it as a “sweet spot.” ¹ Management also says it believes it has leased up the majority of the sweet spot, which is why it is able to discuss the play publicly now. ¹

On positioning and how it was sourced:

• The leased area is southeast of EOG’s Eastern Eagle Ford acreage. ¹
• The acreage was acquired primarily through organic leasing, with some small acquisitions at an average cost of about $1,200 per acre. ¹

On early drilling that underpins the leasing/commercial status:

• EOG has drilled about 12 high-rate-of-return wells (in the earlier description) that confirm strong economics and meet its hurdle rates. ¹
• It cites payouts of less than 1 year at $65 WTI and returns over 100% on the drilled wells referenced in that update. ¹
• In a follow-up, EOG states it has drilled 20 net wells on the acquired acreage achieving less than 1-year payout at $65 WTI. ²
• It also points out that the play was used as an extension to the Eagle Ford acreage and that the extension achieves less than 1-year payout at $65 WTI. ²

Inventory implication of the leasing (how “complete” the leasing is operationally):

• In the ~60,000-acre sweet spot, EOG identifies about 125 remaining 2-mile locations, which it says adds about one additional full year of drilling inventory at current pace for the San Antonio division. ¹

Bottom line on leasing status: EOG is not describing Austin Chalk leasing as an ongoing open-ended land grab; instead, it characterizes the program as largely “leased up” in the core sweet spot with remaining work focused more on delineation (“extent”) and converting the leased position into drillable inventory. ¹

2) How Chalk will be integrated into development plans in South Texas

EOG’s answer to capital-allocation and integration is that Austin Chalk will be treated as an extension/adjacent element inside its core Eagle Ford development activity, rather than as a stand-alone capital program that displaces Eagle Ford.

A) Capital allocation “mix” with core Eagle Ford

In direct response to how capital allocation will work between Chalk vs. “legacy foundation” in the Eagle Ford, EOG says:

• Chalk and the core Eagle Ford will be “equally within our core Eagle Ford development” from a capital allocation standpoint. ³
• It frames Chalk as part of the mix alongside standard Eagle Ford development over the next handful of years. ³
• It specifically characterizes the Austin Chalk sweet spot as a “play…extension or bypass” value opportunity that adds to divisional value creation. ³

Interpretation: EOG is signaling that Chalk will be feathered into the same South Texas operational/development framework (timing and capital allocation), using Eagle Ford activity levels as the pacing reference rather than creating a separate, parallel development cadence. ³¹

B) Technical/operational integration logic (what EOG says enables “feathering”)

EOG also emphasizes why Chalk fits operationally and economically into its broader domestic platform:

• It says the Chalk opportunity required applying high-temperature, high-pressure operational learnings from Dorado to push it forward in South Texas. ³
• It calls this an example of leveraging technical and operational expertise across divisions and “play extensions or bypass pay.” ³

Interpretation: The integration plan is not just capital mixing; it’s also capability mixing—using Dorado-based operational experience to improve execution in the Chalk segment while still developing it within the Eagle Ford development program. ³

3) Comparison: Chalk vs. Eagle Ford and other “legacy foundation” assets

EOG’s framing suggests three levels of relationship: (1) Chalk is an extension to Eagle Ford, (2) it is resourced as part of core Eagle Ford development, and (3) it leverages broader basin learnings rather than standing apart.

A) Chalk vs. core Eagle Ford proper

EOG states Chalk will be integrated directly into Eagle Ford development:

• Chalk will sit “pretty much in the mix” of standard Eagle Ford proper core development over the next handful of years. ³
• Chalk is “southeast of” Eastern Eagle Ford acreage, and EOG sees it as an Eagle Ford acreage extension. ¹²

On economics comparability:

• EOG says total liquids yields are very comparable to Eagle Ford proper. ¹
• It characterizes well economics as competitive, citing mid-range similarity: returns over 100% at $65 WTI and payout under 1 year, and stating that this is competitive and “right in the middle with [their] core Eagle Ford asset.” ¹

Interpretation: Chalk is being treated as a neighboring, geologically/economically compatible add-on rather than a fundamentally different development model requiring separate hurdle rates or a different capital pipeline. ³¹

B) Chalk vs. legacy “foundation” in Eagle Ford (how capital tradeoffs are described)

EOG does not describe Chalk as competing for capital with Eagle Ford’s structural foundation; instead it says capital allocation will be equal within the core Eagle Ford development. ³

Interpretation: Based on the transcript, the “tradeoff” question is answered by integration, not by reallocation. Chalk is meant to augment inventory and returns within the Eagle Ford development umbrella. ³¹

C) Chalk vs. other EOG legacy/basin assets (how learnings cross basins)

EOG’s transcript uses Dorado as the specific cross-basin operational analog for Chalk execution (high-pressure/high-temperature learnings). ³ Separately, it mentions broader proof of integration and use of expertise across portfolio and divisions. ³

Interpretation: While the question asks “vs. the Eagle Ford and other legacy assets,” the provided excerpts mainly establish that Chalk is integrated into South Texas using cross-basin operational learnings—not that Chalk will compete against other legacy assets for capital. ³

4) What remains to be resolved (extent/delineation)

Although EOG says it leased up most of the sweet spot, it also notes:

• It is still trying to figure out the extent of it (even after leasing the majority). ¹
• It continues to gather data and evaluate its extent. ²

Interpretation: The near-term “status” is that leasing is largely done for the sweet spot core, while engineering/geologic follow-through is ongoing to confirm the full development envelope. ¹²

---

Conclusion

• Leasing status in Austin Chalk: EOG has leased ~60,000 acres and believes it has leased up the majority of the sweet spot, supported by early drilling economics (e.g., <1-year payout at $65 WTI and >100% returns on referenced wells) and a quantified inventory impact of ~125 remaining 2-mile locations adding roughly one additional year of drilling inventory at current pace. ¹²
• Integration into South Texas development plans: EOG intends to feather Chalk into the development program by treating it as part of the core Eagle Ford development capital mix, i.e., “equally” within core Eagle Ford development and “pretty much in the mix” of standard Eagle Ford proper over the next several years. ³
• Versus Eagle Ford and other legacy assets: The excerpts characterize Chalk as an Eagle Ford extension with liquids yields comparable to Eagle Ford proper, and they emphasize operational learning transfer (notably from Dorado high-temperature/high-pressure operations) to support Chalk execution—rather than describing Chalk as displacing legacy Eagle Ford capital. ³¹²
