EXHIBIT(a)(1)(J)


This announcement is neither an offer to purchase nor a solicitation of an offer
to sell any Shares. The Offer is made solely by the Offer to Purchase dated June
12, 2002, and the related Letter of Transmittal and any amendments or
supplements thereto, and is being made to all holders of Shares. Neither Conoco
Canada nor Conoco is aware of any jurisdiction in which the making of the Offer
or the acceptance of shares in connection therewith would not be in compliance
with the laws of such jurisdiction. If either Conoco or Conoco Canada becomes
aware of any valid law in a jurisdiction prohibiting the making of the Offer or
the acceptance of Shares pursuant thereto, Conoco Canada may, in its sole
discretion, take such action as Conoco Canada may deem necessary to make the
Offer in any such jurisdiction. The Offer is not being made to (nor will tenders
be accepted from or on behalf of) holders of Shares in any jurisdiction in which
the making of the Offer or the acceptance thereof would not be in compliance
with the laws of such jurisdiction.

                        GULF INDONESIA RESOURCES LIMITED
                                       FOR
                        U.S.$13.25 FOR EACH COMMON SHARE

                         CONOCO CANADA RESOURCES LIMITED
                          A WHOLLY OWNED SUBSIDIARY OF

                                   CONOCO INC.

    Conoco Canada Resources Limited, a Nova Scotia, Canada corporation ("Conoco
Canada") and a wholly owned subsidiary of Conoco Inc., a Delaware corporation
("Conoco"), is offering to purchase all of the outstanding common shares, par
value U.S.$0.01 per share (the "Shares"), of Gulf Indonesia Resources Limited, a
New Brunswick, Canada corporation ("Gulf Indonesia"), not owned by Conoco
Canada. The offer to purchase is being made at a price of U.S.$13.25 per Share,
net to the seller in cash, without interest thereon (the "Offer Price"), upon
the terms and subject to the conditions set forth in the Offer to Purchase dated
June 12, 2002 (the "Offer to Purchase"), and in the related Letter of
Transmittal (which, together with any amendments or supplements thereto,
collectively constitute the "Offer").

    ------------------------------------------------------------------------
      THE OFFER EXPIRES AT 6:00 P.M., NEW YORK TIME, ON JULY 19, 2002,
      UNLESS THE OFFER IS EXTENDED.
    ------------------------------------------------------------------------

    The Offer is subject to certain conditions, including there having been
validly tendered and not properly withdrawn, at the expiration of the Offer,
more than 50% of the Shares then outstanding (calculated on a fully diluted
basis) not owned by Conoco Canada, its affiliates or certain other persons.

    The Offer is being made pursuant to a Support Agreement dated as of June 7,
2002 (the "Support Agreement"), by and among, Conoco, Conoco Canada and Gulf
Indonesia. Following the consummation of the Offer, Conoco Canada has agreed to
use its best efforts to consummate a second-step transaction (the "Second-Step
Acquisition") to acquire all remaining Shares not tendered in the Offer if the
conditions to such Second-Step Acquisition have been satisfied or waived. The
Second-Step Acquisition would be effected under the laws of New Brunswick,
Canada pursuant to a compulsory acquisition or a statutory transaction such as
an amalgamation, arrangement or share consolidation.

    THE BOARD OF DIRECTORS OF GULF INDONESIA AND A COMMITTEE OF INDEPENDENT
DIRECTORS OF GULF INDONESIA (THE "INDEPENDENT COMMITTEE") HAVE (I) APPROVED THE
OFFER AND THE SUPPORT AGREEMENT AND (II) DETERMINED THAT THE OFFER IS FAIR TO
THE SHAREHOLDERS OF GULF INDONESIA (OTHER THAN CONOCO CANADA) AND IN THE BEST
INTERESTS OF GULF INDONESIA AND THE SHAREHOLDERS OF GULF INDONESIA (OTHER THAN
CONOCO CANADA). THE BOARD OF DIRECTORS OF GULF INDONESIA AND THE INDEPENDENT
COMMITTEE RECOMMEND THAT SHAREHOLDERS OF GULF INDONESIA ACCEPT THE OFFER AND
TENDER THEIR SHARES IN THE OFFER.

    For purposes of the Offer, Conoco Canada will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not properly
withdrawn if, as and when Conoco Canada gives oral or written notice to The Bank
of New York (the "Depositary") of its acceptance for payment of such Shares.
Upon the terms and subject to the conditions of the Offer, payment for Shares
accepted pursuant to the Offer will be made by deposit of the purchase price
thereof with the Depositary, which will act as agent for tendering shareholders
whose Shares have been accepted for payment. In all cases, payment for Shares
accepted pursuant to the Offer will be made only after timely receipt by the
Depositary of (i) certificates for such Shares or a confirmation of a book-entry
transfer of such Shares into the Depositary's account at The Depository Trust
Company ("DTC") pursuant to the procedures set forth in the Offer to Purchase,
(ii) the Letter of Transmittal (or facsimile copy thereof), properly completed
and duly executed, with any required signature guarantees or, in the case of a
book-entry transfer, an Agent's Message (as defined in the Offer to Purchase)
and (iii) any other required documents. Under no circumstances will interest
on the purchase price for Shares be paid by Conoco Canada, regardless of any
delay in making such payment.

    The term "Expiration Date" shall mean 6:00 p.m., New York time, on July 19,
2002, unless and until Conoco Canada (in accordance with the terms of the
Support Agreement) shall have extended the period of time during which the Offer
is open, in which event the term "Expiration Date" shall mean the latest time
and date on which the Offer, as so extended by Conoco Canada, shall expire. Any
such extension will be followed by a public announcement thereof no later than
9:00 a.m., New York time, on the next business day after the previously
scheduled Expiration Date. During any such extension, all Shares previously
tendered and not properly withdrawn will remain subject to the Offer, subject to
the rights of a tendering shareholder to withdraw such shareholder's Shares
other than in connection with an extension pursuant to Rule 14d-11 under the
Securities Exchange Act of 1934, as amended (which, in any event, must comply
with Canadian law). Without limiting the manner in which Conoco Canada may
choose to make any public announcement, Conoco Canada will have no obligation to
publish, advertise or otherwise communicate any such announcement other than
by issuing a press release, except as may be required by applicable law.

    Tenders of Shares made pursuant to the Offer are irrevocable except that
such Shares may be withdrawn at any time until Conoco Canada has accepted for
payment Shares that have been tendered in the Offer. In addition, if Conoco
Canada has not accepted Shares validly tendered into the Offer for payment by
August 11, 2002, tendering shareholders can withdraw such Shares at any time
thereafter until Conoco Canada accepts such Shares for payment. Once Shares are
accepted for payment, they cannot be withdrawn unless Conoco Canada has not
deposited with the Depositary funds to pay for such Shares within three business
days of such Shares having been accepted for payment. For a withdrawal to be
effective, a written or facsimile transmission notice of withdrawal must be
timely received by the Depositary at one of its addresses set forth in the Offer
to Purchase.

    Any such notice of withdrawal must specify the name of the person having
tendered the Shares to be withdrawn, the number or amount of Shares to be
withdrawn and the names in which the certificate(s) evidencing the Shares to be
withdrawn are registered, if different from that of the person who tendered such
Shares. The signature(s) on the notice of withdrawal must be guaranteed by an
Eligible Institution (as defined in the Offer to Purchase), unless such Shares
have been tendered for the account of an Eligible Institution. If Shares have
been tendered pursuant to the procedure for book-entry transfer set forth in the
Offer to Purchase, any notice of withdrawal must specify the name and number of
the account at DTC to be credited with the withdrawn Shares. If certificates for
Shares to be withdrawn have been delivered or otherwise identified to the
Depositary, the name of the registered holder and the serial numbers of the
particular certificates evidencing the Shares to be withdrawn must also be
furnished to the Depositary prior to the physical release of such certificates.
Withdrawn Shares may be retendered by again following one of the procedures
described under "THE OFFER--Procedure for Tendering Shares" in the Offer to
Purchase at any time prior to the Expiration Date. All questions as to the form
and validity (including time of receipt) of any notice of withdrawal will be
determined by Conoco Canada, in its sole discretion, whose determination will be
final and binding on all parties.

    The information required to be disclosed by Rule 14d-6(d)(1) of the
Securities Exchange Act of 1934, as amended, is contained in the Offer to
Purchase and is incorporated herein by reference.

    The Offer to Purchase, the related Letter of Transmittal and other relevant
documents will be mailed to record holders of Shares whose names appear on Gulf
Indonesia's shareholder lists and will be furnished to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the names
of whose nominees, appear on the shareholder lists or, if applicable, who are
listed as participants in a clearing agency's security position listing, for
subsequent transmittal to beneficial owners of Shares.
