• Total WCSB production flat at 16.7 Bcfd ± 0.2 Bcfd

• Decline in production from connected wells

• Rate additions from new wells onstream provide growth

• Wells onstream since 1989 produce 80% of gas

Supply Challenge: Sustain Production

• WCSB supplies 25% of consumption in US and Canada

9Higher production rates require higher production replacement

• Supply additions were 1.7 Bcfd in 1990, peaking at 3.9 Bcfd in 2001; 3.7 Bcfd in 2004

• Shallow declines in early years; first year decline has increased from less than 30% to 40%

• Rate additions for all wells onstream in year is the peak monthly rate

economic margin

• Rate added by new connections declined to 250 Mcfd per zone (2004)

• Threshold size of an economic well decreased as gas price and netback increased

• Expanded opportunity set: smaller, higher cost, lower quality, higher risk or more remote prospects

• Summary

Agenda

14

To provide a comparison to the US production, we have adopted the US Energy Information Administration (EIA) definition of unconventional gas:

“Natural gas extracted from coalbeds (coalbed methane) and from low permeability sandstone and shaleformations (tight sands and gas shales) is commonly referred to as unconventional gas. Most of these resources must be subjected to a significant degree of stimulation (e.g., hydraulic fracturing) or other “unconventional” production techniques to attain sufficiently economic levels of production.”

Identification Issues• U.S. agencies currently report natural gas production in

the Lower 48 states from conventional and “unconventional” sources

• Canadian agencies do not (yet) distinguish production from tight sand or shale reservoirs from conventional gas production

• The Alberta EUB only recently began to identify production from coalbed methane wells separately

• Confidentiality provisions delay some information release, thus potentially obscuring more recent trends

Coalbed Methane Opportunities and Challenges

• Significant resource potential

• Value drivers increasing with strengthening of commodity prices and technology improvements

• Due to their location, CBM properties often have the benefit of existing infrastructure and stakeholder familiarity

• Surface land and land user impacts

• Major challenges– sufficient resources of permeability-thickness – (the cost of) water handling

24

• No current recognized gas production from shale zones

• Values for resource estimates large numbers

• Experimental work being undertaken – results are confidential

• Some production occurring as commingled production with sand stringers, whether inadvertent or planned

– Shallow– Jean Marie– Deep Basin

• Summary

Agenda

26

• In the US, “tight gas reservoirs generally are defined as gas-bearing rocks with an in-situ permeability to gas of less than 0.1 md” (Spencer, 1989)

• Since in-situ permeability data is not publicly reported for gas zones in the WCSB, we have estimated tight gas production on the basis of a number of criteria, including stratigraphic group, geographic region, the occurrence of fracture stimulation or horizontal drilling and depth

What is Tight Gas?

Page 14: Tight Gas in Western Canada - Forward Energy Group Inc

Tight Gas in Western Canada July 2005

27

• For the purpose of this analysis, we illustrate three types of tight gas plays, as examples: – Shallow (SE Alberta/SW Sask.)– Jean Marie– Deep Basin

• Definition of the Deep Basin characteristics:– Gas charged area in west-central Alberta (and parts of BC), just

east of the Foothills disturbed belt– Located in recent to Jurassic stratigraphic groups– Deeper than 6000 ft

• A large portion of these reservoir rocks are low permeability, or ‘tight’

• Well depth: 7000-11,000 ft; average 8400 ft; predominantly vertical

• The Deep Basin play produced about 2.6 Bcfd, 15% of 2004 WCSB production

Deep Basin Deliverability Class

• Extraordinary growth in the number of low rate (<0.5 MMcfd and 1-2 MMcfd) connections since 1995; number of connections in the higher rate classes has remained relatively constant

• Rate additions from lower deliverability wells (<2.0 MMcfd) increased from 30% to 65% of annual rate additions

Pushing the marginal economic limit has lead to growth in overall rate additions from lower deliverability wells

Agenda

Page 25: Tight Gas in Western Canada - Forward Energy Group Inc

Tight Gas in Western Canada July 2005

49

• Outstanding issues:

– No clear working definition of tight gas

– Lack of accepted characterization of plays and resources

– Size and scope of resource potential/opportunity is not agreed

– Focus on enabling technologies not as well understood

• Resolution: Forward Energy is embarking on a tight gas characterization project

– Multi-client

– Wide support: industry, government, agency

– Multi-year

Where To From Here?

A solid grounding in the definition and extent of tight gas in the WCSB required - to lead to solid investment decisions

50

• The WCSB is a large, diverse and dynamic basin; many opportunities available to all types and sizes of operators

• Unconventional gas is one of the few components of the WCSB with sustainable growth potential

• CBM is in relative infancy in Canada; tight gas is a continuing program

• Tight gas, developed through the resource play mechanism, is a major focus for selected operators

• Technology developments have been, and will continue to be a major factor in resource development

Key Messages

The sky is not falling - the sky is growingThe challenge is cost-effective rate additions
