Petro-Reef Resources Ltd. (TSX VENTURE:PER), ("Petro-Reef" or the "Company") is
pleased to announce a production increase of 181 BOE/day and a 12% increase in
proved plus probable reserves.


Petro-Reef has tied in its Alexander 09-12-56-27W4 step-out well producing from
the Detrital oil zone. The well came on stream on October 26, 2011, and during
the first 19 days on production the well has flowed at an average rate of 193
BOE/day (181 BOE/day net) - 151 bbl/day (142 bbl/day net) of oil and 247 mcf/day
(232 mcf/day net) of natural gas. Petro-Reef has a 94% working interest in the
9-12 well.


The Company believes that this step-out well in Section 12 confirms that the
Detrital oil trend extends west from Section 7 where Petro-Reef has three wells
producing from the same zone. The Company has completed the reprocessing of 35
sections of 3-D seismic data on its Alexander lands which has been incorporated
into the October 1, 2011 independent reserves evaluation, prepared by McDaniel &
Associates Consultants Ltd. ("McDaniel") (the "McDaniel Update Report"). Four
additional Detrital development locations have been included in the McDaniel
Update Report.


Petro-Reef's gross proved plus probable reserves at October 1, 2011 indicated an
increase of 12% to 1,771,150 BOE from 1,580,000 BOE at December 31, 2010, after
extensions, technical revisions, discoveries, acquisitions, economic factors,
and production. After considering the production for the period January 1 to
September 30, 2011 of 180,300 BOE, the 2011 reserve additions totalled 371,450
BOE which represents an increase of 24% over the 2010 year end reserves.


Using a 10% net present value ("NPV"), the value of proved plus probable
reserves at forecast prices and costs (before income taxes) was unchanged at
$34,735,200 as compared with proved plus probable reserves of $34,741,400 as at
December 31, 2010.


Petro-Reef's gross proved, probable plus possible reserves at October 1, 2011
totaled 2,623,050 BOE. Using a 10% NPV, the value of proved, probable plus
possible reserves at forecast prices and costs (before income taxes) totaled
$56,281,100. The possible reserves include four potential development locations
targeting the Detrital zone offsetting the Company's recent 09-12-56-27W4 well.


Only extensions to the existing producing zones were included in the possible
reserves. The resource plays in the Nordegg at Goose River and the Wabamum and
other plays identified by the seismic reprocessing at Alexander were not
included in the evaluation.


Proved plus probable reserves were comprised of 47% natural gas and 53% crude
oil and natural gas liquids (December 31, 2010 - 54% natural gas and 46% crude
oil and natural gas liquids).


Of the total proved plus probable reserves reported (using forecast prices)
Petro-Reef's reserves are 54% proved and 46% probable.


Based on proved plus probable reserves and production volumes, Petro-Reef's
reserve life index was 7.0 years (41.1 years remaining life) on a proved plus
probable basis at October 1, 2011 compared with 4.2 years (39.8 years remaining
life) at the end of 2010.


Summary of Oil and Gas Reserves - Forecast Prices and Costs

The table below provides a summary of the oil and natural gas reserves
attributable to Petro-Reef as at October 1, 2011. As the tables below summarize
the data contained in the McDaniel Update Report, they may contain slightly

Notes:



1.  Inflation rates for forecasting prices and costs. 
2.  Exchange rates used to generate the benchmark reference prices in this
    table. 
3.  Product sale prices will reflect these reference prices with further
    adjustments for quality and transportation to point of sale. 
4.  Forecast prices and costs as supplied by our independent and qualified
    reserves evaluator, McDaniel.



The McDaniel Update Report, effective October 1, 2011, was prepared in
accordance with National Instrument 51-101 - Standards of Disclosure for Oil and
Gas Activities and the COGE handbook, and is dated November 21, 2011.


Estimates are prepared such that there is a 90% probability that at least the
estimated proved reserves will be recovered and a 50% probability that at least
the sum of the estimated proved reserves plus probable reserves will be
recovered. Possible reserves are those additional reserves that are less certain
to be recovered than probable reserves. There is a 10% probability that the
quantities actually recovered will equal or exceed the sum of the estimated
proved plus probable plus possible reserves.

exploration and production company with producing properties in Alberta, Canada.

BOE Reference

Reference is made to barrels of oil equivalent ("BOE"). BOE may be misleading,
particularly if used in isolation. In accordance with National Instrument
51-101, a BOE conversion ratio of six mcf of natural gas to one bbl of oil has
been used, which is based on an energy equivalency conversion method primarily
applicable at the burner tip and does not represent a value equivalency at the
wellhead.
