Wyo. Stat. § 30-5-125
Each person now or hereafter purchasing or taking for transportation gas produced from gas wells or from oil wells from any owner or producer shall purchase or take ratably without discrimination in favor of any owner or producer, over any other owner or producer in a pool. Such person shall not discriminate in the quantities purchased, the basis of measurement, or the gas transportation facilities afforded for gas of like quantity, quality, and pressure available from such wells. For the purpose of this act reasonable differences in quantity taken or facilities afforded shall not constitute unreasonable discrimination if such differences bear a fair relationship to differences in quality, quantity, or pressure of the gas available or to the acreage attributable to the well, market requirements, or to the relative lengths of time during which such gas will be available to the purchaser. In the event any such purchaser or person taking gas for transportation is likewise a producer or owner, he is hereby prohibited from discriminating in favor of his own production or production in which he may be interested, and his own production shall be treated as that of any other producer or owner producing from gas wells in the same pool.
