Austin Chalk Play Map
Austin Chalk Horizontal Production
Summary
The graphic above presents all Austin Chalk horizontal wells completed in the Eagle Ford Play since 2008.
Typically considered a legacy play, the peak of Austin Chalk development occurred in the 90s. However, horizontal development has seen a slight uptick in recent years, with the majority of modern development being concentrated in the “Karnes Trough”.
This highly fractured chalk reservoir is sourced by the underlying Eagle Ford Shale. The Austin Chalk ranges in thickness from 150’ – 800’ and has many named members, commonly divided into an upper chalk, middle marl, and lower chalk. Productivity relies heavily on interconnected natural fracture networks present in the brittle chalk zones.
Methodology Overview
VSO sourced landing bench and production data from IHS to prepare these maps.
