Re: Withdrawal of Registration Statement on Form S-3 (File No. 333-131596)

Ladies and Gentlemen:

        Pursuant to Rule 477(a) under the Securities Act of 1933, as amended, Pioneer Drilling Company, a Texas corporation (the "Company"), hereby request the immediate withdrawal of the Registration Statement on Form S-3 (Accession No. 0001047469-06-001423, File No. 333-131596), which was filed with the Commission on February 6, 2006 (the "Registration Statement").

        The Registration Statement was filed inadvertently by the Company's financial printer on Form S-3 rather than Form S-3ASR. No securities have been sold pursuant to the Registration Statement. Accordingly, the Company hereby requests the immediate withdrawal of the Registration Statement and will file a new registration statement on Form S-3ASR.

        If you have any questions or concerns with regard to any of the foregoing, please contact Ted Paris (713) 229-1838 or Ben Hance (713) 229-2076 of Baker Botts L.L.P.

    Sincerely,

 

 

PIONEER DRILLING COMPANY
