             GASCO ENERGY PROVIDES PRODUCTION AND OPERATIONS UPDATE
                     SEQUENTIAL MONTHLY PRODUCTION RISES 20%

DENVER - (PR Newswire) - January 4, 2005 - Gasco Energy,  Inc. (AMEX: GSX) today
provided an interim production and operations update on its Riverbend Project in
Utah's Uinta Basin.

Monthly Production
Estimated  cumulative  monthly  production  for December  2004 was 200.2 million
cubic feet equivalent (MMcfe) gross, or 49.9 MMcfe net. This is a 20.0% increase
from November  cumulative  gross  production of 166.8 MMcfe and a 20.2% increase
from November net  production  of 41.5 MMcfe.  Production  increases,  partially
offset by normal  production  declines in existing wells,  are attributed to the
completion of a new well as described below,  and to the November  completion of
the Riverbend gathering system expansion and compression upgrades.

Drilling Activity
Gasco is currently  drilling its twelfth well spudded  during  fiscal year 2004,
the Federal  31-21 (GSX:  22.5% - 30% WI). It is the final well  spudded in 2004
and is being drilled with the company's third rig, which was recently contracted
from Nabors  Industries.  The Federal 31-21 is located in Gasco's Riverbend Area
and is intended to test the Wasatch, Mesaverde and the Blackhawk formations to a
proposed total depth of 12,890 feet.

In  addition,  Gasco's  other two  drilling  rigs are moving  onto  location  to
commence  drilling the Gate Canyon 41-19 (GSX: 75% - 100% WI) well and the State
24-16 (GSX: 30% WI). Both wells are intended to test the Wasatch,  Mesaverde and
Blackhawk formations.

Completion Activity
During  December  2004,  Gasco  completed  one well,  the Federal 21-6 which was
completed in the Blackhawk  Formation.  At the end of December  2004, two wells,
the Federal 22-30 and the Federal 41-3, awaited completion.
