         Cimarex Announces Third-Quarter Production Volumes and Provides
                                Operations Update


DENVER,  October 30, 2007 - Cimarex Energy Co. (NYSE:  XEC) today announced that
third-quarter  2007 oil and gas production  volumes averaged 448.5 million cubic
feet equivalent per day (MMcfe/d), up from 447.5 MMcfe/d in the third quarter of
2006.

Reflecting  positive  results from new  horizontal  oil wells in  southeast  New
Mexico and West Texas,  third-quarter oil production grew 12.5% to an average of
20,537  barrels per day. Gas  production in the latest  quarter  averaged  325.2
million cubic feet per day (MMcf/d) versus 338.0 MMcf/d a year-earlier.

Third-quarter  prices  are  expected  to be in the  range of $6.35 to $6.45  per
thousand cubic feet of gas and $71.25 to $71.75 per barrel of oil.

Exploration and Development Activity
Cimarex  drilled 345 gross (199 net) wells  during the first nine  months  ended
September 30, 2007,  completing 92% as producers.  Exploration  and  development
capital  investment for 2007 is projected to be approximately $1 billion focused
on oil and gas plays principally located in the Mid-Continent, Permian Basin and
Gulf Coast areas of the United States.  Drilling activity remains active with 31
operated rigs currently running.

Mid-Continent
- -------------
Cimarex drilled 191 gross (97 net) wells in the Mid-Continent  region during the
first three quarters of 2007,  completing 96% as producers.  Third-quarter  2007
Mid-Continent  production volumes averaged 194.3 MMcfe/d, an increase of 6% over
third-quarter 2006.

Texas Panhandle  Granite Wash drilling totaled 70 gross (51 net) wells with 100%
completed as producers.  Notable wells  commencing  production  during the third
quarter include the Wilson 2-217 (90% working interest) at 7.1 MMcfe/d, DD Payne
B3H (50%  working  interest) at 2.7  MMcfe/d,  Hobart Ranch 67-18 (100%  working
interest) at 2.1 MMcfe/d, Earp 58-4 (80% working interest) at 2.0 MMcfe/d.



Anadarko Basin and Southern Oklahoma drilling totaled 69 (22 net) wells with 91%
being completed as producers.  Wells in this area recently commencing production
include the Barney 1-29 (l00%  working  interest) at 4.9 MMcfe/d and the Harrell
A9 (100% working interest) at 3.8 MMcfe/d.

Twelve  operated  rigs  are  currently  drilling  in the  Mid-Continent  region,
including six in the Texas Panhandle.

Permian Basin
- -------------
Permian  Basin  drilling for the first nine months of 2007 totaled 122 gross (80
net) wells, 92% of which were completed as producers. Third-quarter 2007 Permian
Basin production  volumes averaged 145.1 MMcfe/d,  a 12% increase over the third
quarter of 2006. Permian third-quarter 2007 oil production reached a record high
9,557 barrels per day, 18% greater than the third quarter of 2006. Increased oil
production is a result of successful  horizontal  drilling programs in southeast
New Mexico and West Texas.

Year-to-date  southeast New Mexico drilling totaled 47 gross (32 net) wells with
89% being  completed  as  producers.  Recent  wells  brought  on  production  in
southeast New Mexico  include the Crow Flats 16 State 2H (73% working  interest)
at 350 barrels of oil per day, Home State Com 1 (100%  working  interest) at 3.0
MMcfe/d and the State HH 2 (100% working interest) at 2.9 MMcfe/d.

A total of 21 gross (12 net) wells were drilled in West Texas, of which 90% were
successful.  In Ward and Winkler Counties  drilling totaled 15 gross (seven net)
horizontal  wells in the  Third  Bone  Spring  formation.  As a  result  of this
program, Third Bone Spring gross production has increased from approximately 600
BOE/d in early to 2006 to nearly 5,000 BOE/d currently.

Cimarex has 15 operated rigs drilling in the Permian Basin,  including  seven in
southeast New Mexico and eight in West Texas.

Gulf Coast/Gulf of Mexico
- -------------------------
Cimarex  drilled 32 gross (23 net) Gulf Coast wells during the first nine months
of 2007,  completing 69% as producers.  Third-quarter 2007 Gulf Coast production
volumes averaged 67.5 MMcfe/d,  a decrease of 8% from third-quarter 2006 volumes
of 73.0  MMcfe/d.  Fluctuations  in Gulf  Coast  volumes  reflect  the timing of
production additions from new wells relative to natural reservoir declines.



Current year Yegua/Cook Mountain drilling in Liberty and Hardin Counties,  Texas
has totaled 12 gross (ten net) wells with an 83% success  rate.  Wells  recently
commencing  production  include the  Grammier 1 (98%  working  interest)  at 5.8
MMcfe/d,  Blackstone Rock Creek 1 (100% working interest) at 5.6 MMcfe/d and the
Barbeaud 1 at 3.5 MMcfe/d.

Offshore activity is currently focused on production  facility  installations in
the Main  Pass  area.  Third-quarter  2007  Gulf of  Mexico  production  volumes
averaged 32.6 MMcfe/d, as compared to 51.4 MMcfe/d in the third quarter of 2006.
Decline in offshore  production is a result of natural  reservoir decline and an
inactive drilling program.

Cimarex has four operated rigs drilling onshore along the Texas Gulf Coast.

Cimarex will release its  third-quarter  2007  financial  results on  Wednesday,
November  7, 2007 before the market  opens and will host a follow-up  conference
