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 has identified and leased about 60,000 acres in the Austin Chalk, describing the acreage as a “sweet spot.” 1 The company indicates it is “pretty much” fully leased up within that sweet spot to the extent that it feels comfortable discussing it publicly now. 1
In terms of how much development inventory this creates, EOG states that within the ~60,000-acre sweet spot it has identified about 125 remaining 2-mile locations, which equates to ~1 additional full year of drilling inventory for its San Antonio division at current Eagle Ford activity levels. 1
Cost and early performance indicators from early drilling:
Geologic/operational positioning vs. Eagle Ford: EOG characterizes the Austin Chalk sweet spot as southeast of its Eastern Eagle Ford acreage. 1 It also notes that the Austin Chalk is a bit more down-dip (deeper and more mature), making it a more “combo play” with more associated gas, though total liquids yields are very comparable to Eagle Ford proper. 1
EOG’s commentary suggests the company is not talking about broad, open-ended leasing everywhere, but rather about a bounded, high-return sweet spot that it believes is largely leased up. 1 In the specific leasing update, management says it “really feel[s] like we’ve leased up the majority of the sweet spot,” which is the main reason it is able to “talk about it right now.” 1
At the same time, EOG says it is still trying to figure out the extent of the play, implying the sweet spot has been defined enough for value creation and planning, while additional delineation/extent work remains ongoing. 1
In the Q&A framing, management is asked whether it should be assumed that EOG is “done leasing” and, separately, how Chalk will affect capital allocation in South Texas versus Eagle Ford’s structural base. 3
EOG’s direct response on capital allocation is that Chalk will be treated as part of the core Eagle Ford development rather than as a standalone program:
EOG also explains why Chalk fits technically into its South Texas development model:
EOG’s integration language indicates Chalk is not displacing the Eagle Ford development thesis; rather, it is treated as an incremental addition to the same operational/capital framework:
So, the “legacy foundation” (core Eagle Ford) remains the base plan, while Chalk is folded in as a sweet-spot resource opportunity/play extension. 41
While the question asks about “Eagle Ford and other legacy assets,” the excerpts provide more direct evidence comparing Chalk’s operational integration with EOG’s ability to apply its playbook across basins, rather than a basin-by-basin capital priority ranking.
EOG highlights cross-basin operational transfer in Chalk specifically (Dorado learnings into Chalk). 4 And more generally, EOG describes its strategy as applying technical and operational expertise across its portfolio to enhance economics of both new basins and older legacy basins, using exploration/play-analog learnings. 5
In addition, management stresses that it aims to add value and improve returns profiles within divisions—again consistent with Chalk being an integrated value-add on top of foundational assets rather than a new separate “legacy replacement” category. 4
If you interpret the question as whether Chalk will get preferential capital versus Eagle Ford: based on EOG’s own language, the company does not describe Chalk as receiving segregated or separate capital treatment; it describes Chalk as part of the same integrated core Eagle Ford development system. 4

EOG reports that the Austin Chalk lease play has progressed to a development-ready position, leasing about 60,000 acres at roughly $1,200/acre and building a robust inventory of high-return wells. Chalk is being feathered into South Texas development alongside the Eagle Ford, not treated as a standalone program, with ~125 remaining 2-mile lateral locations and a multi-year plan that leverages Dorado learnings to optimize capital allocation.

Answer outline
EOG reports that the Austin Chalk leasing effort is largely complete in the sweet spot, about 60,000 acres, and will be blended into South Texas' Eagle Ford development rather than run as a stand-alone program. The company frames Chalk as an incremental extension, leveraging Dorado learnings and internal expertise to extend core Eagle Ford activity with an additional drilling inventory tail for the San Antonio division.

Answer outline
EOG reports about 60,000 acres leased in the Austin Chalk sweet spot, with the majority secured and Chalk being feathered into South Texas development as an extension of the Eagle Ford program. The economics are competitive with Eagle Ford, and Chalk adds roughly a year of drilling inventory while leveraging Dorado's HTHP learnings to improve execution.

Answer outline
EOG reports Austin Chalk leasing has advanced to the sweet spot with roughly 60,000 acres leased and about 125 remaining two-mile locations; Chalk is being feathered into South Texas development as an extension of the core Eagle Ford program. The play maintains strong economics, supports sub-1-year payouts at $65 WTI, and leverages Dorado learnings to extend asset life within a unified capital-allocation framework.

Answer outline
EOG confirms about 60,000 acres leased in the Austin Chalk, with the majority leased, enabling public discussion. Chalk is treated as an extension to Eagle Ford and will be feathered into South Texas development over the next several years, leveraging shared operating capabilities and similar liquids economics. The program is integrated within the core Eagle Ford development rather than treated as a separate priority, supported by ongoing validation of economics and drilling inventory.
