Exhibit 99.1

     CIMAREX ENERGY REPORTS SECOND-QUARTER 2006 EARNINGS OF $0.98 PER SHARE

    DENVER, Aug. 2 /PRNewswire-FirstCall/ -- Cimarex Energy Co. (NYSE: XEC)
today reported second-quarter 2006 net income of $82.9 million, or $0.98 per
diluted share. This compares to second-quarter 2005 earnings of $52.5 million,
or $0.98 per diluted share.

    Revenues from oil and gas sales in the second quarter of 2006 were
$300.5 million, compared to $185.0 million in the same period of 2005.
Second-quarter 2006 cash flow from operations totaled $235.9 million versus
$132.7 million in the same period of 2005(1).

    The increases in revenues, earnings and cash flow are due to higher
production volumes and higher oil prices.

    Second-quarter 2006 oil and gas production averaged 448 million cubic feet
equivalent per day (MMcfe/d), a 52% increase over the same period a year
earlier.  Gas production rose 46% to 338.7 million cubic feet per day and oil
volumes increased 75% to 18,213 barrels per day.  Current quarter production
volumes reflect a full three months of output from the properties acquired in
the Magnum Hunter merger on June 7, 2005.

    Second-quarter 2006 gas prices decreased 4% to $6.22 thousand cubic feet
(Mcf) and oil rose 30% to $65.67 per barrel.

    For the six month period ended June 30, 2006, Cimarex reported net income
of $193.0 million, or $2.27 per diluted share, up from the $95.8 million, or
$1.98 per diluted share for the comparable period of 2005.  First-half 2006
cash flow from operations totaled $463.0 million versus $233.4 million in the
same period of 2005(1).

    Capital

    Second-quarter 2006 exploration and development (E&D) expenditures totaled
$281.7 million, up from $141.0 million in the second quarter of 2005.  In the
second quarter of 2006, we participated in drilling 134 gross (80.1 net)
wells, with an overall success rate of 89%.  We expect full-year 2006
exploration and development expenditures to approximate $1 billion.

    Hedging

    Cimarex has entered into natural gas collars for calendar 2007 and 2008
for 70,000 and 40,000 MMBtu per day, respectively.  The floor price protects
our return on capital invested in the Mid-Continent drilling program while
still allowing participation in potential price increases up to the ceiling.
The collars have been executed to settle against regional delivery points that
correspond with Mid-Continent production and have been designated as hedges
under SFAS No. 133, Accounting for Derivative Instruments and Hedging
activities.  The prices in the table below are at the Mid-Continent delivery
point.

    Oil and gas collars, assumed as part of the Magnum Hunter acquisition,
also remain in place.  These contracts have not been designated for hedge
accounting treatment.  The following table summarizes the open contracts as of

    Outlook

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

    With the contribution from several high-rate Gulf Coast wells, continued
active drilling programs in the Mid-Continent and Permian Basin, and numerous
other factors we estimate that second-half 2006 production volumes will range
between 455-475 MMcfe/d, resulting in full-year 2006 volumes of
455-465 MMcfe/d.

    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
  Depreciation, depletion and amortization       2.35  -    2.45
  General and administrative expense             0.25  -    0.28
  Production taxes (% of oil and gas revenue)     6.5% -     7.5%

    Management believes that the non-GAAP measure of cash flow from operations
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.
