CALGARY, Feb. 14 /CNW/ - Peyto Energy Trust ("Peyto") is pleased to
present the results of our independent reserve report effective December 31,
2005. The evaluation encompassed 100% of the Trust's reserve assets and was
conducted by Paddock Lindstrom and Associates in compliance with National
Instrument 51-101.

Highlights

- The net present value (NPV) discounted at 5% of the total proved
  reserves grew 66% from $1.5 billion in 2004 to $2.5 billion in 2005.
  Adjusting for debt and equity this NPV grew 63%.
- The NPV discounted at 5% of the proved plus probable additional
  reserves grew 62% from $2.0 billion in 2004 to $3.2 billion in 2005.
  Adjusting for debt and equity this NPV grew 57%.
- The proved developed reserve life increased 14% from 10.1 years in 2004
  to 11.5 years in 2005. This reserve life grew due to the maturation of
  our tight gas wells and the scheduling of new processing capacity in
  the greater Sundance area.
- The proved plus probable additional reserve life increased 10% from
  17.1 years to 18.9 years. This growth in reserve life reflects Peyto's
  unique ability to internally generate its own high quality investments.
  The team continues to successfully replace what it develops with new
  opportunities.
- Proved producing, total proved and proved plus probable additional
  reserves increased 24%, 20% and 18% respectively from 2004 to 2005.
- Peyto replaced over 310% of its annual production with new proved
  producing reserves while replacing close to 400% with new proved plus
  probable additional reserves.
- Our reserve and value growth was achieved by focusing 100% of our
  capital investments into internally generated projects. Peyto did not
  have to participate in the marginal acquisition market of 2005.

-------------------------------------------------------------------------


- The reserve life index is calculated by dividing the reserves (in boes)
  in each category by the annualized average production rate in boe/year.
  Peyto believes that the most accurate way to evaluate the current
  reserve life is by dividing the proved developed reserves by the actual
  fourth quarter average production. In our opinion, for comparative
  purposes, the proved developed reserve life provides the best measure
  of sustainability.

- The reserve replacement ratio is determined by dividing the yearly
  change in reserves before production by the actual annual production
  for the year.

Analysis

There are two fundamental questions that we believe should be answered
from this annual evaluation.

- Base Reserves - How did the "base reserves" that were on production in
  the last reserve report perform based on twelve more months of data?

- Value Creation - How much value did our 2005 capital investments
  create?

Base Reserves

Simply put, the new estimate for last year's proved developed producing
reserves (base reserves) is within 99.3% of the previous estimate, after
adjusting for the 2005 production. This difference is certainly within the
margin of error for this kind of evaluation. We are pleased to report that our
base reserves are meeting our expectations stated a year ago and the
additional twelve months of data has enhanced the confidence in this
evaluation.

Value Creation

Our capital investments in 2005 were funded from a combination of
cashflow, debt and equity. In order to assess how much the value per unit has
increased year over year we need to know the change in NPV of the assets, the
change in net debt and the change in units outstanding.
At year end 2005, we estimate that the net debt had increased by $51
million over the past year while the number of units outstanding has increased
from 96.6 million to 103.5 million. These estimates take into consideration
all of our capital expenditures and the total fixed and performance based
compensation paid out during the year. We believe these estimates are
accurate, however they remain unaudited at this time. After adjusting for
changes in debt and equity, the proved plus probable NPV discounted at 5% is
worth $28.25/unit, or 57% more today than a year ago.
In our opinion, it is important to identify the amount of value created
by the capital invested during the year. We undertake this exercise to
determine the best use of the unitholders' capital on a go forward basis. In
order to assess how much value was created during the year from our capital
program, the independent engineers have run last year's NPV with this years
price forecast to eliminate the change in value attributable to the commodity
price forecast. For example, when we look at the total proved case
undiscounted, we can see that our capital program created $1 billion worth of
NPV (NPV created by drill bit in table below). The following table breaks out
the value creation for both the total proved and proved plus probable cases.

The 2005 growth per unit in debt adjusted NPV for the total proved

program accounted for 34% of this growth in value, while the change in
forecasted commodity prices accounted for the other 66%. The following table

The growth in our fundamentals has been accomplished with the drill bit
while maintaining our low operating costs, long reserve life and after the
2005 cash distribution of $136.6 million to unitholders.
Peyto has a reserves committee of independent board members which reviews
the qualifications and appointment of the independent qualified reserve
evaluators. The committee also reviews the procedures for providing
information to the evaluators. All booked reserves are based upon annual
evaluations by the independent qualified reserve evaluators. The evaluations
are conducted from the fundamental geological and engineering data. Peyto
believes this is the most stringent standard of reserves governance available
to the industry, and that it goes well beyond external reviews or audits of
reserves.

Distribution Increase

A committee of Peyto's independent directors has approved a distribution
increase of $0.02 per unit per month to be paid on March 15, 2006. This
represents a 17% increase from the current distribution. We feel comfortable
that this increase passes our sustainability test when we consider the
following business conditions:

- After adjusting for changes in debt and equity, the value of the
  Trust's reserve assets are worth at least 50% more today than a year
  ago.
- The proved developed reserve life has increased 14% from 10.1 years in
  2004 to 11.5 years in 2005.
- We have a 2006 hedged gas price of $9.91/mcf on over 50% of our current
  after royalty production.
- On February 13, 2006 the AECO gas price for the remainder of 2006 was
  trading at $7.64/gj or $8.94/mcf.
- Despite the recent volatility in short term natural gas prices, the
  long term contracts have strengthened. For example, over the past year
  the one year contract for the period of November 1, 2009 to October 31,
  2010 is up 50% and over the last three months is up 14%. When converted
  for Peyto's heating value, this long term contract currently trades at
  over $9/mcf.
- A significant reduction in the 2006 base decline rate from the previous
  year, based on the Dec 31, 2005 independent engineering report.

While production per unit in 2005 remained stable, we were successful in
growing the value of the Trust independent of commodity prices. Peyto is in a
stronger position today to create wealth for our unitholders than ever before.
We will continue to execute on our strategy to invest Peyto's capital in
projects that provide a strong financial return and add to our solid oil and
natural gas foundation.
For more in depth discussion of the 2005 reserve report an interview with
the management will be available on our website by Friday February 17, 2006.

equivalency conversion method primarily applicable at the burner tip and does
not represent a value equivalency at the wellhead. Some values set forth in
the tables above may not add due to rounding. It should not be assumed that
the estimates of future net revenues presented in the tables above represent
