FOR IMMEDIATE RELEASE


                     SEVEN SEAS TO SELL PRODUCING PROPERTIES



December 14, 2002 - HOUSTON,  TEXAS - Seven Seas  Petroleum Inc.  (AMEX:  "SEV")
announced  that  its  Colombian  subsidiaries  entered  into an  Asset  Purchase
Agreement with Sociedad  Internacional  Petrolera S.A.  ("Sipetrol") for sale of
the  subsidiaries'  interest in the shallow Guaduas Oil Field,  inclusive of the
40-mile Guaduas-La Dorada Pipeline effective December 13, 2002.

Sipetrol Agreement

     Sipetrol has agreed to purchase the combined 57.7% participating  interests
and related assets of Seven Seas Petroleum Colombia,  Inc., GHK Company Colombia
and Petrolinson  S.A. in the shallow Guaduas Oil Field.  Sipetrol is currently a
32.9% owner of participating  interest in the shallow Guaduas Oil Field and is a
party to a Joint Operating Agreement with the subsidiaries. The basic terms are:

|X|  The purchase price is $20 million subject to certain adjustments and taxes

|X|  The effective time is 7:00 am on December 13, 2002

|X|  The Closing is contingent  on obtaining  governmental  approvals  from both
     Chile  and  Colombia  and the  consent  of  Chesapeake  Energy  Corporation
     pursuant to the Note Purchase and Loan Agreement between Chesapeake and the
     Company, among other things

|X|  The Closing is expected to occur in late January or early February

|X|  GHK Company Colombia will continue to operate the shallow Guaduas Oil Field
     pending Closing

Auction Process

     The Company engaged CIBC World Markets ("CIBC") to provide financial advice
in late September, 2002. CIBC commenced an auction process to sell the producing
interests in the Guaduas Oil Field.  This  included  establishing  data rooms in
Houston and in Colombia and  soliciting  interests  from fifty  companies.  Nine
companies went through the data rooms. Bids from several prospective buyers were
received  in  mid-November  and this  process  resulted  in the  agreement  with
Sipetrol today.

Remaining Assets and Operations

     After  the  sale,  the  only  material   assets  of  the  Company  and  its
subsidiaries  will be the rights  associated  with the Deep  Dindal  association
contract  and  certain  Colombian  tax  assets.  Neither  the  Company  nor  its
subsidiaries  will have  sufficient  cash to conduct any additional  exploration
activities.

     The Company has been  actively  seeking to secure  additional  financing or
find a partner to  participate  in the completion of the Escuela 2 well and test
the commercial  potential of the Deep Dindal prospect.  To date, the Company has
been  unsuccessful  in these  efforts;  however,  the Company is continuing  its
efforts to find a third party to provide  the  necessary  financing  to test the
Escuela 2 well. Even if tested,  there are no assurances that the Escuela 2 well
would be productive and provide additional value.

     After  December 15, 2002,  the Company may be in default  under the 12-1/2%
$110 Million Senior Subordinated Notes. Now that the financial  circumstances of
the  Company  are  more  clearly  defined,   the  Company  will  accelerate  its
discussions with representatives of the Senior Subordinated Noteholders.

     The Company has  received  notice from  Chesapeake  that it is currently in
default under its 12% $45 Million  Senior  Secured Notes ("$45 Million  Notes").
Chesapeake,  as the collateral agent for the $45 Million Notes,  holds a lien on
the stock of all of the Company's subsidiaries and its cash accounts.

AMEX Listing

     As previously  announced Seven Seas has been notified by the American Stock
Exchange ("AMEX") that the Company fails to meet specific listing standards. The
Company  previously  submitted a plan to the AMEX to remedy these  deficiencies;
however,  based upon the present  circumstances,  the Company cannot satisfy the
AMEX standards.
