Okla. Stat. tit. 52, § 52-36.6: Ownership of gas

All natural gas which has previously been reduced to possession,

and which is subsequently injected into underground storage fields,

sands, reservoirs and facilities, shall at all times be deemed the

property of the injector, his heirs, successors or assigns. In no

event shall such gas be subject to the right of the owner of the

surface of said lands or of any mineral interest therein, under

which said gas storage fields, sands, reservoirs, and facilities

lie, or of any person other than the injector, his heirs, successors

and assigns, to produce, take, reduce to possession, waste, or

otherwise interfere with or exercise any control thereover. With

regard to natural gas in a stratum, or portion thereof, which has

not been condemned or otherwise purchased under the provisions of

this act:

1. The injector, his heirs, successors and assigns shall not

lose title to such gas if such injector, his heirs, successors or

assigns can prove by a preponderance of the evidence that such gas

was originally injected into the underground storage;

2. The injector, his heirs, successors and assigns, shall have

the right to conduct such tests, at his sole risk and expense

including, but not limited to, the value of any lost production of

other than the injector's gas, as may be reasonable to determine

ownership of such gas; and

3. The owner of the stratum shall be entitled to such

compensation as is provided by law.
