Exhibit 99.1

         CIMAREX REPORTS THIRD-QUARTER 2006 EARNINGS OF $1.11 PER SHARE

    DENVER, Nov. 6 /PRNewswire-FirstCall/ -- Cimarex Energy Co. (NYSE: XEC)
today reported third-quarter 2006 net income of $94.0 million, or $1.11 per
diluted share. This compares to third-quarter 2005 earnings of $64.1 million, or
$0.76 per diluted share.

    Revenues from oil and gas sales in the third quarter of 2006 were $309.3
million, compared to $343.5 million in the same period of 2005. Third-quarter
2006 cash flow from operations totaled $241.7 million versus $217 million in the
same period of 2005(1).

    Third-quarter 2006 gas prices decreased 19% to $6.35 per thousand cubic feet
(Mcf) and oil rose 12% to $66.57 per barrel from the same period of 2005.

    Third-quarter 2006 oil and gas production averaged 447.5 million cubic feet
equivalent per day (MMcfe/d), as compared to 445.8 MMcfe/d for the same period a
year earlier. The current quarter's daily production was comprised of 338
million cubic feet of gas and 18,255 barrels of oil.

    "Our quality reserve base continues to provide solid financial results and
our process of rationalizing peripheral assets continues," said F.H. Merelli,
Cimarex's Chairman, Chief Executive Officer and President. "Operational
challenges on several significant onshore producers and completion delays in the
Gulf of Mexico have affected production. Drilling results have been impacted by
increased service costs and by less than expected exploration success. All of
these factors force further high-grading of the drilling program and increased
emphasis on cost reductions."

    Included in the current quarter's net income is an $18.3 million gain on
sale of certain limited partnership interests in oil and gas properties. Net
sales consideration received to date via distributions from these affiliated
partnerships totaled $57.9 million.

    For the nine months ended September 30, 2006, Cimarex reported net income of
$287 million, or $3.41 per diluted share, up from the $159.9 million, or $2.63
per diluted share for the comparable period of 2005. Cash flow from operations
for the first nine months of 2006 totaled $704.7 million versus $450.4 million
in the same period of 2005(1). Nine month results for the prior year reflect the
impact of the Magnum Hunter merger beginning on June 7, 2005.

    Capital

    In the third quarter of 2006 we drilled 125 gross (81.0 net) wells and
exploration and development (E&D) expenditures totaled $249.7 million, up from
$192.9 million in the third quarter of 2005. We expect full-year 2006
exploration and development expenditures to approximate $1 billion.

    Hedging

    Cimarex has hedged a portion of its natural gas production through collars
covering calendar years 2007 and 2008 for 80,000 and 40,000 MMBtu per day,
respectively. The floor price protects our return on capital invested in certain
Mid-Continent drilling programs while still allowing participation in potential
price increases up to the ceiling. The prices in the table below are at the
Mid-Continent delivery point.

    Exploration and Development Activity

    Cimarex drilled 429 gross (269.9 net) wells during the first nine months of
2006, with a completion rate of 92%. At the present time we have 27 operated
rigs running.

    Mid-Continent

    Cimarex drilled 235 gross (146.2 net) wells in the Mid-Continent region
during the first three quarters of 2006 realizing a 98% success rate.
Mid-Continent third quarter production volumes averaged 182.7 MMcfe/d, a two
percent increase over second-quarter 2006.

    In the Texas Panhandle, principally targeting the Granite Wash formation at
depths of 11,000-14,000 feet, Cimarex drilled 61 gross (42.6 net) wells with a
97% success rate. Meaningful wells recently brought on production in the Texas
Panhandle area include the Webb 5-194 (100% working interest) at 3.6 MMcfe/d,
Webb 4-194 (75% working interest) at 3.4 MMcfe/d, Earp 3-60 (100% working
interest) at 2.7 MMcfe/d and the Earp 3-59 (75% working interest) at 2.4
MMcfe/d.

    Exploitation activity in the Panoma gas field, also located in the Texas
Panhandle, consisted of drilling 75 (73.4 net) infill wells with a 100% success
rate. These wells target the Brown Dolomite formation at 2,200 feet. This
drilling has increased gross field production by 5.1 MMcfe/d.

    In the Anadarko Basin of western Oklahoma, Cimarex drilled 71 gross (13.1
net) wells realizing a 99% success rate. Wells in this area generally target the
Red Fork and Clinton Lake/Atoka at depths of 12,000-15,000 feet. A notable
Clinton Lake well, the Patricia 1-29 (56% working interest), commenced
production averaging 6.5 MMcfe/d. In southern Oklahoma, Cimarex drilled 13 gross
(10.4 net) wells with an 85% success rate including the Eola Robberson field's,
Harmon Heirs 4-8H (100% working interest) producing at 2.0 MMcfe/d.

    Cimarex currently has 11 operated rigs drilling in the Mid-Continent region.

    Permian Basin

    Permian Basin drilling for the first nine months of 2006 totaled 125 gross
(92.0 net) wells, 97% of which were completed as producers. Permian Basin
third-quarter 2006 production volumes averaged 130.2 MMcfe/d as compared to
137.6 MMcfe/d in the second quarter of 2006.

    In southeast New Mexico, two wells the Laguna Deep 8 (94% working interest)
and the New Mexico DD State 3 (100% working interest) declined rapidly as a
result of smaller than anticipated reservoir size and/or water encroachment. Net
daily production from these two wells decreased 5.3 MMcfe/d from the second to
the third quarter of 2006. Year-to-date southeast New Mexico drilling totaled 43
gross (31.6 net) wells with a 93% success rate in the Morrow, Atoka and Strawn
formations. Initial production rates averaged 1.5 MMcfe/d. Notable wells in Eddy
County, New Mexico include the Ozley 25 (100% working interest) at 2.9 MMcfe/d,
White City 31 (100% working interest) at 2.7 MMcfe/d and the Parks 1 (62.5%
working interest) at 2.6 MMcfe/d.

    In West Texas, a total of 70 gross (51.9 net) wells were drilled, of which
99% were successful. Included in the West Texas program is exploitation of the
Westbrook Unit (90% working interest) where 32 infill wells have been drilled
and completed in the Clearfork formation at 3,200 feet. Other geologic targets
in West Texas include the Devonian, Ellenburger, Bone Springs and Spraberry.
Cimarex has drilled or participated in 17 (5.8 net) Devonian wells in the Arbol
de Nada field, five gross (five net) Ellenburger wells in the Will-O field, and
four gross (1.8 net) Bone Springs wells in the War-Wink field.



    Cimarex has 11 operated rigs drilling in the Permian Basin, six in southeast
New Mexico and five in West Texas.

    Gulf Coast

    Cimarex drilled 37 gross (21.2 net) Gulf Coast area wells during the first
nine months of 2006, realizing a 65% success rate. Gulf Coast third-quarter 2006
production volumes averaged 72.9 MMcfe/d as compared to 76.4 MMcfe/d in the
second quarter of 2006.

    Net production from the Donald Harrington #1 (100% working interest) in
south Louisiana, Rich #1 (100% working interest) and the Galloway Gas Unit #1,
both in Liberty County Texas, cumulatively decreased 5.4 MMcfe/d from the second
to the third quarter of 2006. The decrease in production from these wells is a
result of increased water production in the primary zone, mechanical well bore
failure and natural decline.

    Year-to-date Cimarex drilled or participated in 12 gross (7.7 net) Liberty
County wells, eight of which were successful. The Cimarex-operated Galloway Gas
Unit #2 (50% working interest) commenced production in July and is currently
producing 16 MMcfe/d. In the fourth quarter, first production is expected from
three Kate Dishman (60% working interest) wells at rates of 350 barrels of oil
per day each. In the Mississippi Salt Basin, Cimarex drilled the Blackstone #2
(100% working interest) to a total depth of 16,546 feet. Production commenced in
August at a rate of 5.5 Mcfe/d.

    Cimarex has three operated rigs drilling in the onshore Gulf Coast area.

    Gulf of Mexico

    Third-quarter Gulf of Mexico production volumes averaged 51 MMcfe/d, up from
46 MMcfe/d in the second quarter of 2006. Shut-in production volumes related to
damage from last year's hurricanes decreased to approximated 1-2 MMcfe/d in the
third quarter from 10-15 MMcfe/d in the second quarter. In addition, 6 MMcfe/d
of production in the Main Pass area has been consistently curtailed because of
weather-related difficulties impacting barging operations. To prevent such
ongoing delays, work is proceeding to tie-in Main Pass oil production to a new
pipeline which is expected to be completed in early 2007.

    Net volumes of 15-20 MMcfe/d from discoveries at Main Pass 185 (47% working
interest), Main Pass 187 (100% working interest) and Main Pass 200 (50% working
interest) are expected to begin in the first quarter of 2007. Cimarex will
resume drilling on its Main Pass operated blocks in November. However, Cimarex
has elected to market its operated Main Pass assets. The sales package includes
these three discoveries as well as interest in 40 total blocks and 15 billion
cubic feet equivalent of proved reserves.

    Outlook

    The following statements provide a summary of production and certain expense
projections for the remainder of 2006.

    We estimate that fourth-quarter 2006 production volumes will range between
445-455 MMcfe/d, resulting in full-year 2006 volumes of 450-455 MMcfe/d.
Fourth-quarter volume estimates have been negatively impacted by Gulf Coast
operational issues, less than expected exploration success, delays in bringing
on Gulf of Mexico production and completion delays in the Permian Basin.



    Expenses for the remainder of 2006 are expected to fall within the following
ranges:

    Expenses ($/Mcfe):
        Production expense                             $1.00  - $1.10
        Transportation expense                          0.11  -  0.14
        DD&A and ARO accretion                          2.60  -  2.70
        General and administrative expense              0.25  -  0.28
        Production taxes (% of oil and gas revenue)      7.0% -   8.0%

is useful information for investors because it is used internally and is
accepted by the investment community as a means of measuring the company's
ability to fund its capital program. It is also used by professional research
analysts in providing investment recommendations pertaining to companies in the
oil and gas exploration and production industry.
