============================================= ======================= ===================== ========================= ==============

(1)  Covers  900,000  shares  issuable under the Swift Energy Company 2005 Stock
     Compensation Plan(the "Plan").
(2)  Pursuant  to Rule 416 under the  Securities  Act of 1933,  as amended  (the
     "Securities  Act"),  this  Registration  Statement  is  deemed  to  include
     additional  shares issuable under the terms of the Plan to prevent dilution
     resulting   from  any  future  stock  split,   stock  dividend  or  similar
     transaction.
(3)  Estimated solely for the purpose of calculating the registration fee.
(4)  Calculated  pursuant  to Rule  457(c) and (h).  Accordingly,  the price per
     share of the common stock offered  hereunder  pursuant to the Plan is based
     on 900,000 shares reserved for issuance under the Plan at a price per share
     of $46.05, which is the average of the highest and lowest selling price for
     the shares on the New York Stock Exchange on December 16, 2005.
(5)  Each share of common stock is  accompanied  by a preferred  share  purchase
     right pursuant to the Rights Agreement (as Amended and Restated as of March
     31, 1999) between Swift Energy  Company and American Stock Transfer & Trust
     Company, as Rights Agent.
(6)  The registrant  paid a registration  fee of $56,642 in connection  with its
     Registration   Statement  on  Form  S-3  (Reg.  No.   333-64692)   covering
     $350,000,000 that was filed with the Securities and Exchange  Commission on
     July 6, 2001,  and $965 of the unused  $29,630 prior  registration  fee was
     used for  Registration  Statement on Form S-8 (Reg. No.  333-112042)  dated
     January 20, 2004, and $28,315 of the unused $29,630 prior  registration fee
     was used for Registration Statement on Form S-3 (Reg. No. 333-112041) dated
     January 20, 2004, of which  $200,000,000 of unsold securities  remains.  As
     calculated  pursuant  to Rule 457(o) at the  statutory  rate of $117.70 per
     $1,000,000 of securities  registered,  and pursuant to Rule 457(p), $552.62
     which includes $350 of the unused $29,630 registration   fee  paid  for the
     earlier registration statement and $202.62 balance held by the SEC is being
     used  to partially  offset the  $4,878.07  registration  fee  due  for this
     registration statement.

          Stock") set forth in the registrant's  Registration  Statement on Form
          S-3 filed January 21, 2004, (Reg. No. 333-112041), as amended on April

     All  documents  filed by the  registrant  with the  Commission  pursuant to
Sections 13(a),  13(c), 14 and 15(d) of the Securities  Exchange Act of 1934, as
amended  (the  "Exchange  Act"),  subsequent  to the  date of this  Registration
Statement  shall be deemed to be  incorporated  herein by reference  and to be a

Item 4.  Description of Securities.

         Not applicable.

Item 5.  Interests of Named Experts and Counsel.

         Not applicable.

Item 6.  Indemnification of Directors and Officers.

     Swift Energy Company ("Swift") has the authority under Articles 2.02(A)(16)
and 2.02-1 of the Texas Business  Corporation Act to indemnify its directors and
officers to the extent provided for in such statute. Swift's Bylaws, as amended,
provide for  indemnification  of its  officers,  directors  and employees to the
fullest extent  permitted by Article  2.02-1 of the Texas  Business  Corporation
Act. With shareholder  approval,  Swift amended its Articles of Incorporation to
confirm  that  Swift  has  the  power  to  indemnify  certain  persons  in  such
circumstances as are provided in its Bylaws. The amendment allows Swift to enter
into  additional  insurance  and  indemnity  arrangements  at the  discretion of
Swift's board of directors.  Swift has entered into  indemnification  agreements
with each of its officers and directors  that  indemnify  the  individual to the
fullest extent permitted by law.

     Article  1302-7.06(B)  of the  Texas  Miscellaneous  Corporation  Laws  Act
provides  that a  corporation's  articles of  incorporation  may provide for the
elimination  or  limitation  of a  director's  liability.  Swift's  Articles  of
Incorporation  eliminate  the liability of directors to the  corporation  or its
shareholders  for  monetary  damages for an act or omission in his capacity as a
director, with certain specified exceptions to Swift and its shareholders to the
fullest extent permitted by Article 1302-7.06(B)(1-4) of the Texas Miscellaneous
Corporation Laws Act.


                                      II-2



     Swift  maintains  insurance to cover amounts that it may be required to pay
officers  and  directors  under the  indemnity  provisions  described  above and
coverage for its officers and directors against certain  liabilities,  including
certain liabilities under the federal securities law.

Item 7.  Exemption from Registration Claimed.

         Not applicable.

Item 8.  Exhibits.

     The following documents are filed as a part of this registration statement.

          5.1  Opinion of Counsel as to the legality of the shares being offered

          23.1 Consent of Ernst & Young LLP

          23.2 Consent of Counsel (contained in Exhibit 5.1)

          24.1 Powers of Attorney (contained in the signature pages hereto)

          99.1 Swift  Energy  Company  2005 Stock   Compensation  Plan
               (filed with the Commission as Exhibit 10.1 to our report on  Form
               8-K filed on May 12, 2005 and incorporated   by   reference)

Item 9.  Undertakings.

     A.   The undersigned registrant hereby undertakes:

          (1) to file,  during  any  period  in which  offers or sales are being
     made, a post-effective  amendment to this registration statement to include
     any  material  information  with  respect to the plan of  distribution  not
     previously  disclosed in the registration  statement or any material change
     to such information in the registration statement;

          (2) that,  for the  purpose of  determining  any  liability  under the
     Securities Act of 1933, each such post-effective  amendment shall be deemed
     to be a new  registration  statement  relating  to  the securities  offered
     therein, and the offering of such securities  at that time  shall be deemed
     to be the initial bona fide offering thereof; and

          (3) to remove from registration by means of a post-effective amendment
     any  of  the  securities  being  registered  which  remain  unsold  at  the
     termination of the offering.

     B. The  undersigned  registrant  hereby  undertakes  that,  for purposes of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Exchange Act (and, where  applicable,  each filing of an employee benefit plan's
annual  report   pursuant  to  section  15(d)  of  the  Exchange  Act)  that  is
incorporated by reference in the registration  statement shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

     C. Insofar as indemnification  for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
registrant pursuant to the foregoing  provisions,  or otherwise,  the registrant
has been advised that in the opinion of the Commission such  indemnification  is
against  public  policy as expressed in the  Securities  Act and is,  therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction  the  question  of whether  such  indemnification  by it is against
public  policy as  expressed in the  Securities  Act and will be governed by the
final adjudication of such issue.

statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
