(b) Such unit production shall be distributed among or the proceeds thereof paid to the several persons entitled to share in the production from such separately owned tract in the same manner, in the same proportions, and upon the same conditions that they would have participated and shared in the production or proceeds thereof from such separately owned tract had not said unit been organized. The share of the unit production allocated to each separately owned tract shall be delivered in kind to the persons entitled thereto by virtue of ownership of oil and gas rights therein or by purchase from such owners, subject to the right of the unit operator to a lien thereon for payment of unit expenses pursuant to the order of unitization.

Wells drilled or operated on any part of the unit area no matter where located shall, for all purposes, be regarded as wells drilled on each separately owned tract within such unit area.
