Okla. Stat. tit. 12, § 12-393: Attachment of witness for nonattendance

When a witness fails to attend in obedience to a subpoena

(except in case of a demand and failure to pay his fees), the court

or officer before whom his attendance is required may issue an

attachment to the sheriff, coroner or constable of the county,

commanding him to arrest and bring the person therein named before

the court or officer, at a time and place to be fixed in the

attachment, to give his testimony and answer for the contempt. If

the attachment be not for immediately bringing the witness before

the court or officer, a sum may be fixed in which the witness may

give an undertaking, with surety, for his appearance; such sum shall

be endorsed on the back of the attachment; and if no sum is so fixed

and endorsed, it shall be One Hundred Dollars ($100.00). If the

witness be not personally served, the court may, by a rule, order

him to show cause why an attachment should not issue against him.
