E&P delivery - Full production

• Production start – Targeted for next year, from first full site

• Between 2011-2014 targeting 20-50 sites

• Each site planned to consist of 4-6 wells with 24,000 to 40,000 feet of

lateral in each well

• Each site is expected to produce between 7 and 20 Bcf over 15 years

(gross)

• Production from each site is expected to be peak at between 4 and 10

mmscfd (gross) (650 - 1,500 Boepd per site)

• Stable production curve (much flatter and longer than conventional)

• Production technology – known and demonstrated in other markets

Page 13: 20101104-Gas Presentation Slides, Coal Bed Methane

E&P delivery - Surface access

Planning has been obtained for 13 sites to date from variety of land

owners and planning authorities

Land access:

• Peel Environmental agreement gives access to multiple sites in

core licences.

• More than 40 drilling locations identified

• Point of Ayr offshore

Planning:

• King Sturge retained to take multiple drill sites to planning

Water disposal:

• No issues to date because of quality and quantity

• Even local sewer disposal can be possible

Red areas show Peel land holding across

E&P delivery - Market

• IGas operates in a high realisable gas price environment

• Direct access to many large customers

• No material pipeline infrastructure required, legal right to access both

low and high pressure gas networks

• 2011-2012 forward gas prices are ~$7.50mcf (~50p/therm)

• Pricing at National Balancing Point by discounting transportation

achievable

• Sales therefore can be direct or through Grid

Large industrial consumer

What is Coal Bed Methane?

• CBM is the natural gas found in many

coal deposits

• It is used as a fuel in exactly the same

way as conventional gas

• Coal seams can hold large quantities

of gas (six to seven times more than the

equivalent volume of rock in a

conventional gas reservoir)

• Gas is stored within the molecular

structure of the coal, on the surface and

in natural fractures (cleats). Typically

water pressure keeps the gas trapped

• When the water pressure is released,

the gas flows through the fractures into

a well bore where it can be collected

Page 16: 20101104-Gas Presentation Slides, Coal Bed Methane

What is Coal Bed Methane?

• CBM – Methane rich gas

• “Firedamp” in mining terms

• Typical composition:

• Methane 80-95%

• Ethane 0-8%

• Propane + 0-4%

• Nitrogen 2-8%

• CO2 0.2-6%

• Low porosity (0-3%)

Page 17: 20101104-Gas Presentation Slides, Coal Bed Methane

Three Forms of Methane Extraction

• Coal Bed Methane (CBM)

•from virgin seams

• Coal Mine Methane (CMM)

• From prior workings/abandoned

mines

• Underground Coal Gasification (UCG)

• In situ combustion of virgin

seams

• IGas Energy is focussed on CBM only

Site Selection & Data

Page 23: 20101104-Gas Presentation Slides, Coal Bed Methane

Site Selection & Data

• The British Coal (NCB) wireline logs used to locate wells

• Data acquisition is critical, particularly in the early appraisal

stages

• key data include logs, cores ( gas content, desorption

measurements etc)

Four Oak Gamma & Density

Log at Florida horizon

Litholog from recent CBM well

Page 24: 20101104-Gas Presentation Slides, Coal Bed Methane

Site selection & Data

• Coal samples from numerous

boreholes enabled contour maps of coal

seam gas to be established

• detailed structural maps were

developed by integrating the down dip

exploration with the active coal mine

data

Page 25: 20101104-Gas Presentation Slides, Coal Bed Methane

Site Selection & Data

• The abandoned mine plans

provide further data upon

which to select potential

sites.

• This plot shows an area of

working longwall panels that

are completely free from

faulting

• The relatively undisturbed

structure suggests a

promising site to locate

extended horizontal wells

may exist in the vicinity

Page 26: 20101104-Gas Presentation Slides, Coal Bed Methane

Typical well Completion

• The well is drilled and lined with a

cemented steel casing – to provide

isolation from aquifers etc

• The casing is perforated in the target

coal seams

• Water and eventually methane gas are

produced through the tubing to surface

• Artificial lift technology is used to pump

the water/gas to surface (PCP’s, ESP’s,

Jet Pumps, Rod Pumps)

Vertical vs Horizontal Wells

• Successful CBM development is a function of

gas rate

• Historically, this required a high (vertical) well

density (see opposite)

• Such an approach is not viable in the UK

(environmental impact, land access etc)

• Alternative solutions have had to be found

• Horizontal or multi-lateral wells allow

comparable areas of coal to be accessed whilst

minimising the surface impact (as opposite)

• Commercial CBM production is attainable

through a combination of technology application

and innovative approaches to reduce the cost

base.
