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.

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 has identified and leased about 60,000 acres in the Austin Chalk and describes the area as a “true sweet spot.” 1
Management indicates EOG is still figuring out the extent, but believes it has leased up the majority of the sweet spot, which is why it is comfortable discussing it publicly. 1
EOG also characterizes the acquisition as primarily organic leasing, with average costs around $1,200 per acre, and notes small acquisitions contributed as well. 1
On the development confirmation side, EOG reports it has drilled ~12 high-rate-of-return wells to date in this sweet spot. 1 Management further states that payouts are <1 year at $65 WTI and that returns are over 100% on wells drilled so far. 1
EOG provides a related update noting it has drilled 20 net wells on the acquired acreage, also achieving less than 1-year payout at $65 WTI. 2
Inventory sizing: In the identified sweet spot (referenced as ~60,000 acres), EOG states it has identified about 125 remaining 2-mile locations, which adds about 1 additional full year of drilling inventory at current pace to its San Antonio division. 1
Management frames the Austin Chalk position as an extension to Eagle Ford and intends to “feather” Chalk into ongoing development rather than treat it as a separate standalone program. 3 2
EOG attributes the ability to apply Chalk learnings to its high-temperature, high-pressure operations from Dorado, applying those learnings to push forward the Austin Chalk opportunity. 3
Separately, EOG also emphasizes using its technical and operational expertise and a decentralized divisional culture where each division looks for extensions/bypass opportunities and leverages internal expertise. 3
For the Chalk play mechanics, EOG describes the Austin Chalk as sitting southeast of Eastern Eagle Ford acreage, and being more down-dip, deeper/more mature, and a combo play with more associated gas—but with total liquids yields comparable to Eagle Ford proper. 1
A key question from analysts is whether EOG should be “done leasing” and how Chalk affects capital allocation compared with “structural elements” in legacy foundation in the Eagle Ford. 4
EOG’s answer is effectively that Chalk is not replacing the core Eagle Ford program; rather, it is added into the ongoing Eagle Ford development plan:
So, relative to Eagle Ford “legacy” asset foundations, EOG’s stated stance is:
While the question focuses on South Texas vs. Eagle Ford, the excerpts also show how EOG situates Chalk as another example of its playbook across the portfolio:

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.
