Cal. Pub. Resources Code § 3342
To the extent necessary to conform to the provisions and requirements of this article, and to any order of unitization or other order, rule or regulation of the supervisor, made and adopted pursuant hereto, all leases, contracts, and all other rights and obligations shall be regarded as modified and amended, but otherwise to remain in full force and effect. Nothing contained in this article shall be construed to extend the term of any lease or other agreement.
Nothing contained in this article shall be construed to require a transfer to or vesting in the unit operator, or in persons other than those owning the same at the time of the creation of the unit, of title to the separately owned tracts or to any leases or other drilling and operating agreements thereon within the unit area, other than the right to use and operate the same to the extent set out in the order of unitization; nor shall the unit operator or the working interest owners jointly be regarded as owning the unit production. Each respective share of the unit production and the proceeds from the sale thereof shall be severally owned by the persons to whom the same is allocated pursuant to the order of unitization. All property, whether real or personal, which the unit operator may in any way acquire, hold or possess, the cost of which is chargeable to the working interest owners, shall not be acquired, held or possessed for the unit operator for his own account but shall be so acquired, held and possessed by the unit operator for the account of and as agent for each of the several working interest owners and shall be the property of each of such persons as their respective interests may appear under the order of unitization, subject, however, to the right of the unit operator to the possession, management, use or disposal of the same in the proper conduct of the affairs of the unit, and subject to any lien the unit operator may have thereon to secure the payment of unit expense.
No unit order made by the supervisor shall be construed to have the effect of, result in, or in any manner require or provide for the alienation, transfer, conveyance or change of any title or ownership, whether legal or equitable, of any person in or to any separately owned tract of land included in the said order, or to the mineral rights therein, to any other person owning or possessing a separately owned tract of land which may likewise be included in said unit order.
