NAL Oil & Gas Trust Reports 2004 Year-End Reserves

CALGARY--(CCNMatthews - March 2) - NAL Oil & Gas Trust (TSX:NAE.UN) (the "Trust" 
or "NAL") today announced its 2004 year-end reserves, evaluated by McDaniel & 
Associates Consultants Ltd. ("McDaniels"), independent engineering consultants 
in Calgary, in accordance with National Instrument ("NI") 51-101. At December 
31, 2004, the Trust's proved reserves total 26.8 million barrels of oil 
equivalent(*) ("boe"), and proved plus probable (P+P) reserves amount to 37.6 
million boe. The Trust's year-end reserves for 2004 do not include the reserves 
of the recently acquired Addison Energy Inc., as the effective date of that 
transaction was February 1, 2005.

/T/

    Infill drilling and development activities resulted in:

    -  increased reserves attributable to improved recovery of 1,891 thousand
       boes (proved plus probable) over and above the volumes previously
       booked as undeveloped. These increases occurred mainly in the
       Brent/Provost, Medicine River, Alida, Browning, Elswick and Star
       Valley areas.

    -  NAL's proved producing reserves as a percentage of total proved
       reserves increasing from 92.9 percent at year end 2003 to 95.6 percent
       at year end 2004. This was mainly a result of our successful 2004
       drilling program in southeast Saskatchewan, which developed reserves
       previously booked as proved undeveloped.

/T/

The following tables summarize NAL's estimated reserves volumes and values using 
the forward oil and natural gas prices in effect at the close of markets on 
December 30, 2004, the final trading day prior to the effective date of the 
evaluation. Gross reserves volumes are based on company working interests that 
exclude any wells or properties in which NAL has only royalty interests, and are 
before deduction of royalties payable. Net reserves include working interest 
reserves after deducting royalties payable, plus royalty interest reserves.

/T/

    (*) When converting natural gas to equivalent barrels of oil within this
        report, NAL uses the widely recognized standard of 6 thousand cubic
        feet (Mcf) to one barrel of oil equivalent (boe). However, boes may
        be misleading, particularly if used in isolation. A boe conversion
        ratio of 6 Mcf : 1 bbl is based on an energy equivalency conversion
        method primarily applicable at the burner tip and does not represent
        a value equivalency at the wellhead.

The comparable Net Present Value estimates discounted at ten percent using 
McDaniels' price forecast of January 1, 2005 would be $368.8 million for total 
proved, and $486.1 million for total proved plus probable reserves. The actual 
reserves estimates are essentially unchanged by using either the McDaniels price 
forecasts or the forward sales prices.

The Net Present Values shown include ARTC, and are reported before income taxes. 
It should not be assumed that the estimated future net revenue is representative 
of the fair market value of the properties of the Trust. There is no assurance 
that such price and cost assumptions will be attained and variances could be 
material.

Based on our production estimate for 2005 of 12,789 boe per day, NAL's reserve 
life index ("RLI") at December 31, 2004 was 8.0 years for proved plus probable.

Following NAL's February 2005 acquisition of Addison Energy Inc., gross company 
working interest P+P reserves at February 1, 2005 amount to approximately 66.2 
MMboe. Using the Trust's production estimate for the next 12 months, this 
represents an RLI of 8.9 years.

NAL Oil & Gas Trust has a reserves committee, composed entirely of independent 
directors, which is responsible for appointing the Trust's independent 
engineering consultants and determining the scope of the annual reserves review.

NAL Oil & Gas Trust is an open-end investment trust founded in May 1996 that 
generates distributions through the acquisition, development, production and 
marketing of oil, natural gas and natural gas liquids. The Trust owns high 
quality assets in Alberta, Saskatchewan and Ontario. Trust units trade on the 
Toronto Stock Exchange under the symbol "NAE.UN".
