What the Austin Chalk means for your minerals in Atascosa County

A formation name on your royalty statement or division order does not change how your interest is valued. What matters is the income your wells actually pay: average your last three to six royalty checks, then apply the standard multiple of 36 to 72 times your average monthly check, the same as 3 to 6 times your annual royalty. Where you land in that band depends on how fast your Atascosa County wells decline, the operator, your royalty rate, and any undeveloped drilling upside.
