Typical well nonexistent in Austin Chalk
Discoveries of localized large-capacity reservoirs capable of sustaining high-rate production distinguish the current Austin Chalk play from past booms in the S.E. Texas trend. The chalk gained its reputation for high initial potentials with quick decline rates in the area of the Pearsall field in Frio County; this is southwest of the current focus of play in Burleson, Lee, Fayette, Washington, and Gonzales Counties. In this portion of the vast producing trend a different kind of rock exists - one that is highly fractured and gives up large amounts of hydrocarbons for a sustained period. An example of high-rate sustained production is in the Birch Creek area near Lake Somerville in Burleson County. Projected reserves should average 100,000 to 125,000 bbl/well. With varying amounts of associated gas from 400 MMCF to one billion cubic feet. Initial production tests on these wells range from 200 to 500 bopd and 200 MCFD to 3 MMCFD. After several months of production, the wells indicate capacity to hold up to initial performance.
