Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against no board: Oklahoma does not license or register geologists and Okla. Stat. title 59 act list (no geologist act) on 21 September 2026 · Updated 21 September 2026
Oklahoma has a deep petroleum geology workforce, a state geological survey and a large oil and gas regulatory apparatus, and it has never created a professional geologist license. Title 59 of the Oklahoma Statutes, Professions and Occupations, is where the state’s licensing acts live, and its act list contains no geologist chapter. The closest neighboring entry is chapter 31, Foresters. The Oklahoma Geological Survey is a research agency at the University of Oklahoma, not a licensing board.
Nearby states differ, which is where the confusion comes from. Texas licenses professional geologists, Arkansas registers them, Arizona registers geologists through its Board of Technical Registration and Wyoming licenses them under W.S. ch. 33-41. Regional habit is not a guide.
Nothing is prescribed, so the design is yours. One limit still applies, and it is about wording rather than shape. No required diameter, no required legend, no approved artwork and no filing step, so your stamp is a design decision and Acorn will cut it to whatever you want on it. Put your own name, your firm name, and any credential you actually hold, named with the state that issued it. Leave off “Licensed” and “Registered” and any state-issued title unless the state issued you one, and in particular do not combine State of Oklahoma with a professional geologist legend and a number, because there is no such number.

Is a seal required in Oklahoma?
Oklahoma does not license, register or certify geologists, and no Oklahoma agency issues a geologist’s seal. Title 59 of the Oklahoma Statutes, Professions and Occupations, is where the state’s licensing acts live, and its act list contains no geologist chapter; the closest neighboring entry is chapter 31, Foresters. The Oklahoma Geological Survey is a research agency at the University of Oklahoma, not a licensing board. There is no credential to seal with.
What must appear on the seal
- Not applicable: Oklahoma issues no geologist license and prescribes no geologist seal
Nothing is prescribed because nothing is regulated. A geologist practicing in Oklahoma may use a business stamp or an out-of-state credential stamp, but no Oklahoma element list applies and no Oklahoma board approves the artwork. Do not combine the words State of Oklahoma with a professional geologist legend and a number; there is no Oklahoma geologist number and the device implies a credential the state does not grant.
Size and shape
Not applicable. Oklahoma prescribes no geologist seal and therefore no diameter. The sources here are the title 59 act list for a geologist act and found none.
Embosser, rubber stamp or digital
Not applicable. With no Oklahoma geologist credential there is no required instrument. Where geological work reaches a regulated Oklahoma submittal, the seal on it is the professional engineer’s or the professional surveyor’s under OAC 245:15-17-1, and that licensee carries the responsibility.
Signing and dating
Not applicable. No Oklahoma rule prescribes a signature or date for a geologist, because no Oklahoma rule prescribes a geologist seal.
An energy state that never created the license
Oklahoma has a deep petroleum geology workforce, a state geological survey and a large regulatory apparatus for oil and gas, and it has never created a professional geologist license. Title 59 is the state’s professions and occupations title and its act list does not include geologists. Nearby states differ: Texas licenses professional geologists, Arkansas registers them, Arizona registers geologists through its Board of Technical Registration, and Wyoming licenses them under W.S. ch. 33-41. Regional habit is not a guide.
Which documents must be sealed
No Oklahoma document requires a geologist’s seal. Geological content reaching a regulated submittal travels under an engineer’s seal. OAC 245:15-17-2(a) is wide enough to carry it, reaching all final engineering and surveying specifications, reports, drawings, plans, design information, calculations, surveys and plats presented to a client or any public agency.
Electronic and digital seals
Not applicable. No electronic seal standard exists for a profession the state does not regulate.
Renewal, lapse and retirement
Not applicable. There is no Oklahoma geologist license to renew, lapse, retire or revoke.
Firm requirements
Not applicable. Oklahoma registers no geology firms and issues no certificate of authority for geological services. A firm offering engineering alongside geological work needs a certificate of authority under 59 O.S. § 475.21 and must show its name, certificate number and contact information on the document under OAC 245:15-17-2(j).
What to check before you order
There is nothing for an Oklahoma geologist seal to comply with, because Oklahoma issues no geologist license. Do not order a device pairing State of Oklahoma with a professional geologist legend and a number. If you hold a geologist license from a state that does issue one, order that state’s seal to its own specification and use it only there. If you are also licensed in Oklahoma as a professional engineer or professional surveyor, order that seal to Okla. Admin. Code 245:15-17-1(c), which names a one and seven-eighths inch and a one and five-eighths inch seal, and keep the two devices separate.

Frequently asked questions
Does Oklahoma require a geologist to have a seal?
No, and it could not, because it issues no geologist license. The title 59 act list contains no geologist act, so there is no number to inscribe, no legend to letter and no document that calls for the device.
Is there an Oklahoma geologist board?
There is not. The Oklahoma Geological Survey is a research agency at the University of Oklahoma rather than a licensing board, and no Oklahoma statute creates a geology credential or a board to administer one.
What can I put on an Oklahoma geologist stamp?
Whatever is true of you. Your name as you use it professionally, your firm name, contact details, a monogram or logo, and the exact name of any out-of-state credential you hold with its issuing state named alongside. No Oklahoma element list applies and no Oklahoma board approves the artwork.
What should I keep off it?
State of Oklahoma paired with a professional geologist legend and a number. There is no Oklahoma geologist number, and the device would imply a credential the state does not grant. A neutral firm device raises none of those questions.
What size and shape should it be?
Any size and any shape, because Oklahoma prescribes no geologist seal and therefore no diameter. Because nothing is prescribed, the size is yours. The round dies Acorn makes most often for unregulated devices fall between 1-1/2 and 2 inches, and rectangular blocks around 2-1/2 by 1 inch, which is a legibility judgment from our own production rather than any rule.
Who seals geological content on a regulated Oklahoma submittal?
The licensed professional engineer or professional surveyor, under OAC 245:15-17-1. The duty rule at OAC 245:15-17-2(a) is wide enough to carry geology, reaching all final engineering and surveying specifications, reports, drawings, plans, design information, calculations, surveys and plats presented to a client or any public agency.
What does the engineer have to show on that document?
Seal, signature and date, plus firm information. Under OAC 245:15-17-2(j) the firm name, certificate number and contact information appear as text on the document. That is the engineer’s obligation rather than yours, and it is worth knowing when you are coordinating a submission.
Does Oklahoma set an electronic seal standard for geologists?
No electronic seal standard exists for a profession the state does not regulate. A graphic of your own stamp in a PDF is governed by nothing but your own practice.
I am also licensed in Oklahoma as an engineer. Can I combine the devices?
No. Order your engineering or surveying seal to Okla. Admin. Code 245:15-17-1(c), which names a one and seven-eighths inch and a one and five-eighths inch seal, and keep it separate from anything you use to identify geological work.
Does an Oklahoma geology firm need a certificate of authority?
Not for geology. Oklahoma registers no geology firms and issues no certificate of authority for geological services. A firm offering engineering alongside geological work needs a certificate of authority under 59 O.S. § 475.21 and must show its name, certificate number and contact information on the document under OAC 245:15-17-2(j).
