             NATURAL GAS SERVICES GROUP ANNOUNCES THIRD QUARTER AND
                         NINE MONTHS FINANCIAL RESULTS

          20% Increase In Revenue For The Three Months to $3.7 Million
           13% Increase In Revenue For The Nine Months to $9.2 Million

MIDLAND,  Texas, November 4, 2003 - Natural Gas Services Group, Inc. (AMEX:NGS),
a  leading  provider  of  equipment  and  services  to the  natural  gas and oil
industry,  announces its financial results for the third quarter and nine months
ended September 30, 2003.

Revenue  for the third  quarter  ended  September  30,  2003,  increased  20% to
$3,699,556  as compared to $3,081,384  for the same period in 2002.  Revenue for
the nine months  ended  September  30,  2003,  increased  13% to  $9,264,116  as
compared  to  $8,200,940  for the same period in 2002.  The  increase in revenue
during the third  quarter and nine months  reflects an increase in revenue  from
the rental of natural gas compressor  units and a slight increase in service and
maintenance revenue.

Net income for the three months  ended  September  30,  2003,  increased 4% to $
384,407 or $.07 per share  (diluted),  as  compared to net income of $368,932 or
$.08 per share  (diluted)  for the same period in 2002.  Net income for the nine
months ended  September  30, 2003,  increased  15% to $817,442 or $.14 per share
(diluted), as compared to net income of $708,041 or $.15 per share (diluted) for
same period in 2002.  Earnings  Per Share were  affected by the  increase of 1.5
million shares for the initial public offering in the fourth quarter of 2002.

EBITDA (see  discussion of EBITDA at the end of this  release)  increased 13% to
$1,300,933 for the three months ended September 30, 2003,  versus $1,150,993 for
the same period in 2002.  EBITDA  increased  12% to  $3,164,915  for nine months
ended September 30, 2003, versus $2,830,105 for the same period in 2002.

NGS's rental fleet grew by 35% during the nine months ended  September 30, 2003.
The Company ended the quarter with 371 compressor  packages in its rental fleet,
up from 274 units at September 30, 2002.




Wayne Vinson,  President and CEO of Natural Gas Services  Group,  Inc. said, "We
are pleased with our  quarter-over-quarter  growth. Our Year-To-Date  financials
are strong and getting stronger.
Here are some key indicators comparing September 2002 to September 2003:

         Services and Maintenance income up 13% to $1.3 million Leasing income
         up 55% to $5 million. Operating income up 18% to $1.9 million.
         Net income up 15% to $817,442.
         EBITDA up 12% at $3.2 million.
         Diluted Earnings Per Share at $.14.

As the third quarter and nine months  financial  results show,  our core leasing
business remains quite profitable.  We have been able to do this by delivering a
high-value product to the small to mid-sized  compressor market that meets their
critical  needs.  As we continue to focus on the  execution of our marketing and
sales strategies,  we are pleased with the increasing acceptance of our products
and the acceleration of new account penetration. We have a strong balance sheet,
a healthy  backlog and are on track for a successful  fourth  quarter and fiscal
year 2004.  We remain  extremely  optimistic  about our  prospects for continued
growth."

"EBITDA"  reflects net income or loss before interest,  taxes,  depreciation and
amortization. EBITDA is a measure used by analysts and investors as an indicator
of operating non-cash charges and financing costs.  Therefore,  EBITDA gives the
investor information as to the cash generated from the operations of a business.
However,  EBITDA is not a measure  of  financial  performance  under  accounting
principles  generally  accepted in the United  States of America  ("GAAP"),  and
should  not  be  considered  a  substitute  for  other  financial   measures  of
performance.  EBITDA as  calculated  by NGS may not be  comparable  to EBITDA as
calculated and reported by other companies.  The most comparable GAAP measure to
EBITDA is net income. The reconciliation of EBITDA to net income is as follows:
