Okla. Stat. tit. 11 § 27-120
Jurors in the municipal court shall be selected pursuant to this section under the same terms and conditions as are provided for by law for the district courts, or in the alternative, pursuant to Section 18.1 of Title 38 of the Oklahoma Statutes. Upon written request of the judge of the municipal court for a stated number of jurors to the chief judge of the appropriate district court, it shall be the duty of the clerk of the district court to draw from the jury wheel a requested number of jurors in the same manner as is provided by law for the district court until the number requested, who from their addresses appear to reside within the corporate limits of the municipality, is drawn, and to prepare a list of names drawn and certify such list to the judge of the municipal court. On completion of the draw, the clerk shall immediately return to the jury wheel all names drawn which are not placed on the certified list. The judge of the municipal court shall make written request to the chief judge of the district court for a stated number of additional jurors if, after allowance of claimed statutory exemptions, the listed number is found to be insufficient. Summons of the prospective jurors shall be issued as set out by ordinance, and may be served in person by the chief of police or any member of the police force of the municipality, or may be served by the clerk of the municipal court by mail.
