                       [LETTERHEAD OF JENKENS & GILCHRIST,
                           a Professional Corporation]



                                 August 4, 1999



Swift Energy Company
16825 Northchase Drive
Suite 400
Houston, Texas 77060

Ladies and Gentlemen:

     We have acted as  securities  counsel  for Swift  Energy  Company,  a Texas
corporation  ("Swift"),  in connection  with (i) the preparation and filing with
the  Securities  and Exchange  Commission  (the  "Commission")  of  Registration
Statement No.  333-81651 on Form S-3 filed by the Company with the Commission on
June  28,  1999,  and  amended  and  declared  effective  on July 9,  1999  (the
"Registration  Statement")  for the purpose of registering  under the Act, among
other  securities,  common stock of Swift;  and (ii) the  preparation of a final
prospectus  supplement  dated July 30, 1999 (the  "Prospectus  Supplement"),  in
connection with an underwritten public offering (the "Offering") of an aggregate
of up to  4,600,000  shares  of common  stock,  par  value  $.01 per share  (the
"Shares").

     In  connection  with this opinion,  we have  examined  originals or copies,
certified or otherwise  identified to our satisfaction,  of (i) the Registration
Statement,  including the form of prospectus  included therein and the documents
incorporated by reference therein, and the Prospectus  Supplement,  (ii) Swift's
Restated  Articles of  Incorporation  and the  Bylaws,  each as amended to date;
(iii) copies of resolutions of the Board of Directors of the Company authorizing
the issuance of the Shares and related  matters;  and (iv) such other  documents
and  instruments  as we have deemed  necessary  for the  expression  of opinions
herein  contained.  In making the  foregoing  examinations,  we have assumed the
genuineness of all signatures and the authenticity of all documents submitted to
us as  originals,  and the  conformity  to original  photostatic  copies.  As to
various  questions of fact  material to this  opinion,  we have  relied,  to the
extent we deem reasonably  appropriate,  upon representations or certificates of
officers of Swift and upon documents, records and instruments furnished to us by
Swift, without independent check or verification of their accuracy.








         Based upon the foregoing examination, we are of the opinion that:

     1.   the Company is a corporation  duly organized,  validly existing and in
          good standing under the laws of the State of Texas; and

     2.   the Shares to be sold in the Offering,  as described in the Prospectus
          Supplement,  have been duly  authorized  for issuance  and,  when such
          shares are issued and  delivered by Swift to the  Underwriters  in the
          manner and for the consideration stated in the Prospectus  Supplement,
          they will be validly issued, fully paid and nonassessable.

     We hereby  consent  to the  filing of this  opinion  as an  exhibit  to the
Registration Statement and to reference being made to our firm under the caption
"Legal  Opinions"  in the  Prospectus  dated July 9, 1999 and under the  caption
"Legal Opinions" in the Prospectus  Supplement dated July 30, 1999, which form a
part of the Registration  Statement.  In giving this consent, this firm does not
thereby  admit  that it comes into the  category  of  persons  whose  consent is
required under Section 7 of the  Securities Act or the rules and  regulations of
the Commission promulgated thereunder.

     We are  members of the Bar of the State of Texas and do not hold  ourselves
out as being  experts on laws other than laws of the State of Texas and the laws
of the United States of America.


                               Respectfully submitted,

                               Jenkens & Gilchrist, a Professional Corporation
