             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 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: Page 2 of 6
