UNCONVENTIONAL GAS - TRANSFORMATIONAL AND GLOBAL

CBM and shale have transformed the energy landscape in North America and Australia

Europe and Asia have significant untapped unconventional gas resources, rising demand and

increased dependence on imported gas

FAVOURABLE MARKET CONSIDERATIONS

Long term supply deficits

Dependence on gas imports

Security of supply concerns

Large indigenous resource base

High prices

Long-term sector dynamics are favourable

Page 21: Dart Energy Limited - ASX · DART ENERGY CBM PORTFOLIO –SCHEMATIC OVERVIEW Global portfolio of CBM assets –53 licences; 8 countries; biggest onshore licence holder in UK Key CBM

Coal Bed Methane Shale gas Tight gas

Gas is adsorbed onto the

surface of the coal

Gas is “trapped” within

the shale rock

Gas trapped in impermeable

hard rocks or sands

WHAT ARE “UNCONVENTIONALS”?

21

CBM and shale gas is the same end product as

conventional natural gas

Difference is source rock from which natural gas is

produced

Drilling techniques and principles of well completions are

similar to those used in the conventional oil and gas

industry

Advances in horizontal drilling and hydraulic fracturing

make CBM and shale gas economically competitive

surface of the coal the shale rock hard rocks or sands

Conventional natural gas

Gas exists in a free state in

the spaces between the sands

Page 22: Dart Energy Limited - ASX · DART ENERGY CBM PORTFOLIO –SCHEMATIC OVERVIEW Global portfolio of CBM assets –53 licences; 8 countries; biggest onshore licence holder in UK Key CBM

HOW IS IT EXTRACTED?

CBM EXTRACTION

Water is removed from the

coalbeds (“dewatering”),

lowering the pressure in the

22

lowering the pressure in the

coals and the gas is “desorbed”

SHALE GAS EXTRACTION

Water, sand and chemicals are

injected into the rock at high

pressures (“fraccing”) to crack

the rock and liberate the gas

A TYPICAL SHALE WELL.

Deep vertical well with one or more laterals

Main difference is “fraccing” - pumping water

and sand (>98%) and additives (<2%) down

the wellbore at high pressure

The fluid injected at pressure fractures the

shale rock, and the sand (proppant) holds the

cracks open

Process is repeated multiple times along the

lateral wellbore to cover the maximum area

Source: Chesapeake Energy

Fluids are carried up the wellbore for

disposal or treatment and re-use ; sand prop

open the cracks, allowing gas to flow out

WATER

� Water produced is not fit for other uses?

� Water produced affects the soil?

standards ; remaining treated for safe disposal

� Shale formations are typically several thousand

meters below aquifers

� No clear examples of ground water contamination

since 1982(2)

� Multiple safeguards: steel casings, cementing, etc

FRACCING

� New technology?

� Chemicals used are dangerous?

� Gas can migrate to surface?

� Causes earthquakes?

3� Safe “fraccing” dates back to 1950s, over tens of

thousands of wells globally

� >98% water; < 2% “additives” (common in

household products)

� Used for shale; limited use in CBM

� Strictly regulated
