             GASCO ANNOUNCES YEAR-END RESERVE ESTIMATES AND PROVIDES
                          RIVERBEND PROJECT PRODUCTION

DENVER -- April 9, 2003 /PRNewswire / -- Gasco Energy (OTCBB: GASE) today
announced year-end reserve estimates.

Estimated year-end, proved reserves were approximately 21.5 billion cubic feet
equivalent (Bcfe). This marks the first reserve estimates for Gasco based on
recent production from its Riverbend and Wyoming Projects. The company's reserve
mix is 96% natural gas and 4% liquid hydrocarbons with approximately 28% of
total reserves proved developed.

Gasco's estimated, pre-tax future net cash flows discounted at 10% (commonly
known as the Securities and Exchange Commission PV-10 figure) for proved
reserves at year end was $12.3 million. The 2002 PV-10 calculation used net
year-end commodity prices of $3.39 per thousand cubic feet (Mcf) of natural gas
and $29.60 per barrel of crude oil (Bbl). Reserve estimates were prepared by
James R. Stell, a third party, registered petroleum engineer, and conform to the
definition as set forth in the SEC Regulation S-X Part 210.4-10 (a) as clarified
by subsequent Commission Staff Accounting bulletins. The proved reserves are
also in accordance with Financial Accounting Standards Board Statement No. 69
requirements and are available in the company's Report on Form 10-K for the year
ended December 31, 2002.

PRODUCTION UPDATE
Gasco's current gross and net production is approximately 2.9 MMcf/d and 1.25
MMcf/d, respectively. The most recently drilled well, the Lytham 22-22 (100% WI,
pending partner's election) is currently awaiting a pipeline connection and will
be completed as soon as the tie-in is made. The Federal 32-21 is currently
drilling through 11,000 feet and has experienced gas shows in both the Wasatch
and the Mesaverde.

MANAGEMENT COMMENTS
Mark Erickson, Gasco's President and CEO, said: "We are certainly excited to be
able to announce the reserve estimates for Gasco. The majority of the reserves
in this initial report are under our core Riverbend Project in Utah, where Gasco
is focusing its capital investment. This report demonstrates Riverbend's
commerciality while improving our access capital to further develop this
gas-rich resource. We are currently experiencing higher gas prices than those
used in the reserve report and look forward to continued strong prices with the
addition of the Kern River pipeline expansion scheduled for completion in May
2003. We do not see domestic gas supply issues improving in the coming 12 to 18
months, making this an opportune time to continue drilling our acreage. We have
one well drilling ahead and will assess the remainder of 2003's CAPEX as a
function of cash flow and new sources of funding."
