Re:  Registration  Statement on Form S-8 covering 650,000 shares of common stock
     of Swift Energy Company

Ladies and Gentlemen:

     Reference  is  made  to  the  Registration   Statement  on  Form  S-8  (the
"Registration  Statement")  to  be  filed  by  Swift  Energy  Company,  a  Texas
corporation (the "Company"),  with the Securities and Exchange  Commission under
the  Securities  Act of 1933,  as amended (the  "Securities  Act"),  on or about
January 20, 2004,  relating to the  registration of a total of 650,000 shares of
common  stock  (the  "common  Stock") of the  Company  that may be issued by the
Company pursuant to employee benefit plans of the Company, including (i) 500,000
shares of Common  Stock  issuable  pursuant  to the Swift  Energy  Company  2001
Omnibus Stock  Compensation Plan, as amended (the "2001 Plan"), and (ii) 150,000
shares of Common Stock issuable  pursuant to the Swift Energy  Company  Employee
Savings Plan (the "401(k) Plan" which,  together with the 2001 Plan are referred
to collectively as the "Plans").

     In connection  therewith,  I have examined and relied upon the original, or
copies identified to my satisfaction,  of (1) the Articles of Incorporation,  as
amended,  and the Bylaws, as amended, of the Company; (2) minutes and records of
the corporate  proceedings of the Company with respect to the  establishment  of
the Plans,  the issuance of the Shares of Common Stock pursuant to the Plans and
related matters; (3) the Registration Statement and exhibits thereto,  including
the  Plans;  and (4) such  other  documents  and  instruments  as I have  deemed
necessary  for the  expression  of  opinions  herein  contained.  In making  the
foregoing examinations, I have assumed the genuineness of all signatures and the
authenticity of all documents  submitted to me as originals,  and the conformity
to  original  documents  of  all  documents  submitted  to  me as  certified  or
photostatic  copies.  As to various  questions of fact material to this opinion,
and as to the content and form of the Articles of Incorporation, as amended, and
the Bylaws,  as amended,  minutes,  records,  resolutions and other documents or
writings  of  the  Company,  I have  relied,  to the  extent  deemed  reasonably
appropriate,   upon  representations,   statements  or  certificates  of  public
officials or officers or representatives of the Company.

     Based upon my examination,  consideration of, and reliance on the documents
and other matters described above, and assuming that:

(1)  outstanding   incentive  or   nonqualified   options  to  purchase   Shares
     ("Options") were duly granted,  and the Options to be granted in the future
     are duly  granted,  in  accordance  with the terms of the 2001 Plan and the
     Shares to be sold and issued in the future upon the  exercise of Options or
     otherwise will be issued and sold in accordance  with the terms of the 2001
     Plan;

(2)  the Company  maintains an adequate number of authorized but unissued shares
     and/or treasury shares available for issuance to those persons who purchase
     Shares pursuant to the Plans;

(3)  the  consideration  for the Shares issued pursuant to the Plans is actually
     received  by the Company as provided in the Plans and exceeds the par value
     of such Shares; and

(4)  the board of directors  of the Company  authorizes  the annual  issuance of
     shares of Common Stock to the 401(k) Plan;

     I am of the opinion that the Shares issued or sold in  accordance  with the
terms  of  the  Plans  will  be  duly  and  validly   issued,   fully  paid  and
nonassessable.

     The opinion  expressed herein is limited to the laws of the State of Texas,
and  the  federal  laws  of the  United  States  of  America  and we  assume  no
responsibility as to the applicability  thereto,  or the effect thereon,  of the
laws of any other jurisdiction.

     I  hereby  consent  to  the  use  of  this  opinion  as an  exhibit  to the
Registration  Statement.  In giving this consent,  I do not thereby admit that I
come within the category of persons whose consent is required under Section 7 of
the  Securities  Act or rules and  regulations  of the  Securities  and Exchange
Commission thereunder.

     I am delivering  this opinion to the Company,  and no person other than the
Company may rely on it.

                             Respectfully submitted,



                             Karen Bryant
                             General Counsel--Corporate Governance
