Okla. Stat. tit. 52, § 52-287.8: Status and powers of unit - Liability for expenses -

Liens.

Each unit created under the provisions of this act shall be a

body politic and corporate, capable of suing, being sued and

contracting as such in its own name. Each such unit shall be

authorized on behalf and for the account of all the owners of the

oil and gas rights within the unit area, without profit to the unit,

to supervise, manage and conduct the further development and

operations for the production of the oil and gas from the unit area,

pursuant to the powers conferred, and subject to the limitations

imposed by the provisions of this act and by the plan of

unitization.

The obligation or liability of the lessee or other owners of the

oil and gas rights in the several separately-owned tracts for the

payment of unit expense shall at all times be several and not joint

or collective and in no event shall a lessee or other owner of the

oil and gas rights in the separately-owned tract be chargeable with,

obligated or liable, directly or indirectly, for more than the

amount apportioned, assessed or otherwise charged to his interest in

such separately-owned tract pursuant to the plan of unitization and

then only to the extent of the lien provided for in this act.

Subject to such reasonable limitations as may be set out in the

plan of unitization, the unit shall have a first and prior lien upon

the leasehold estate and other oil and gas rights (exclusive of a

one-eighth (1/8) royalty interest) in and to each separately-owned

tract, the interest of the owners thereof in and to the unit

production and all equipment in the possession of the unit, to

secure the payment of the amount of the unit expense charged to and

assessed against such separately-owned tract. The interest of the

lessee or other persons who by lease, contract or otherwise are

obligated or responsible for the cost and expense of developing and

operating a separately-owned tract for oil and gas in the absence of

unitization, shall however, be primarily responsible for and charged

with any assessment for unit expense made against such tract and

resort may be had to overriding royalties, oil and gas payments,

royalty interests in excess of one-eighth (1/8) of the production,

or other interests which otherwise are not chargeable with such

cost, only in the event the owner of the interest primarily

responsible fails to pay such assessment or the production to the

credit thereof is insufficient for that purpose. In the event the

owner of any royalty interest, overriding royalty, oil and gas

payment or other interest which under the plan of unitization is not

primarily responsible therefor pays in whole or in part the amount

of an assessment for unit expense for the purpose of protecting such

interest, or the amount of the assessment in whole or in part is

deducted from the unit production to the credit of such interest,

the owner thereof shall to the extent of such payment or deduction

be subrogated to all of the rights of the unit with respect to the

interest or interests primarily responsible for such assessment. A

one-eighth (1/8) part of the unit production allocated to each

separately-owned tract shall in all events be regarded as royalty to

be distributed to and among, or the proceeds thereof paid to, the

royalty owners free and clear of all unit expense and free of any

lien therefor.
