Tex. Nat. Res. Code § 86.083

The commission shall exercise its authority to adjust correlative rights and opportunities of each owner of gas in a common reservoir to produce and use or sell the gas when evidence introduced at a hearing after proper notice will support a finding made by the commission that the aggregate lawful volume of the open flow or daily potential capacity to produce of all gas wells located in a common reservoir is in excess of the daily reasonable market demand for gas from gas wells that may be produced from the common reservoir, to be used as permitted in this chapter.
