Okla. Stat. tit. 52, § 52-318.3: Notice of intent to drill - Negotiating surface damages

Before entering upon a site for oil or gas drilling, except in

instances where there are non-state resident surface owners, non-

state resident surface tenants, unknown heirs, imperfect titles,

surface owners, or surface tenants whose whereabouts cannot be

ascertained with reasonable diligence, the operator shall give to

the surface owner a written notice of his intent to drill containing

a designation of the proposed location and the approximate date that

the operator proposes to commence drilling.

Such notice shall be given to the surface owner in any manner as

provided for in paragraph 1 and paragraph 2 of subsection C of

Section 2004 of Title 12 of the Oklahoma Statutes for the service by

personal delivery or by mail of a summons in a civil action. If the

operator makes an affidavit that he has conducted a search with

reasonable diligence and the whereabouts of the surface owner cannot

be ascertained or such notice cannot be delivered, then constructive

notice of the intent to drill may be given in the same manner as

provided for the notice of proceedings to appoint appraisers.

Within five (5) days of the date of delivery or service of the

notice of intent to drill, it shall be the duty of the operator and

the surface owner to enter into good faith negotiations to determine

the surface damages.
