Exhibit 99.1

                     Contango Updates Operations

    HOUSTON--(BUSINESS WIRE)--Dec. 6, 2006--Contango Oil & Gas Company
(AMEX:MCF) announced today that it has fracture stimulated ("fraced")
and production tested its first two Fayetteville Shale wells operated
by its alliance partner, Alta Resources LLC ("Alta"), the Alta-Thines
#1-30H in its Pigeon Roost area where it has 5,600 net mineral acres
(approximately 3,900 net to Contango) and the Alta-Ledbetter #1-33H in
its Buck Ridge area where it has 5,100 net mineral acres
(approximately 3,600 net to Contango). The Alta-Thines #1-30H flowed
at approximately 1 million cubic feet per day ("MMcf/d") and is
currently shut-in awaiting hook-up to production facilities, expected
by February 2007. The Alta-Ledbetter #1-33H did not flow commercial
quantities of gas, and has been temporarily abandoned while we
consider various re-completion alternatives.

    The following outlines the Company's wells in the Pigeon Roost and
Buck Ridge areas:

                Pigeon Roost               Buck Ridge
           -----------------------   -----------------------
           Alta-Thines #1-30H        Alta-Ledbetter #1-33H
           Alta-Briggler #1-31H      Alta-Wooten #1-34H
           Alta-Beck #1-32H          Alta-Clark #1-26H
           Alta-Kaufman #1-12H


    The Company plans to drill its next set of wells north of its
Pigeon Roost and Buck Ridge areas in what it considers to be a proven
area of the Fayetteville Shale play, and where Alta has approximately
18,000 net mineral acres (approximately 12,600 net to Contango). Alta
has been designated as operator in the following sections: 29-10N-15W,
4-9N-15W, 8-9N-12W, 18-9N-12W and anticipates drilling its first well
in section 8-9N-12W. Alta could drill up to 32 wells in these four
sections. Alta recently released its second rig to another operator
and has the option of getting this second rig back in February 2007.

    Contango has now been integrated into 73 wells by a third party
operator. Of these, 22 wells are currently producing, 20 wells are
either drilled or awaiting completion, and 31 wells are scheduled to
be drilled.

    In addition, the Company is in negotiations to sell its
wholly-owned subsidiary's, Contango Operators, Inc. ("COI"), 25%
working interest (1.9 billion cubic feet equivalent net to COI) in our
Grand Isle 72 discovery ("Liberty") for $7.0 million. Our
partially-owned subsidiary, Contango Offshore Exploration LLC ("COE"),
will continue to own its 50% working interest. We expect production at
an 8/8ths rate of 8 million cubic feet equivalent per day ("MMcfe/d")
to begin at this well prior to year-end.

    Our Eugene Island 10 ("Dutch") well is also expected to begin
producing prior to year-end at an 8/8ths rate of 30 MMcfe/d.
Production, net to Contango from its Dutch and Liberty wells, is
expected to be approximately 13 MMcfe/d. The location for our Dutch #
2 exploration well is complete and we anticipate spudding this well
prior to year-end.

    Kenneth R. Peak, Contango's Chairman and Chief Executive Officer,
said, "While the Alta-Ledbetter #1-33H well is a disappointment, we
are not sure why the well didn't flow. We are considering various
alternatives, including re-fracing the well. We will also frac and
test the Alta-Clark #1-26H, which is also in Buck Ridge and near our
Alta-Ledbetter #1-33H well, in the first quarter of 2007 using a
different frac technique. In Pigeon Roost we intend to frac our
Alta-Briggler #1-31H well sometime in the first quarter as well."

    Mr. Peak continued, "Drilling operations are a challenge in the
Pigeon Roost and Buck Ridge areas and we have encountered a variety of
difficulties with each of the seven wells we have drilled. We believe
we are still early in the exploration life of this play and that by
experimenting with alternative drilling and fracing techniques, we
will ultimately be able to economically produce the Fayetteville Shale
in these two areas. In the interim, however, as we consider the
necessary drilling, fracing and completion procedures to improve our
performance, we will focus our drilling efforts further north in a
proven, shallower area of the play."
