Self funding
Own investments
Sustainable development built in growth
Expansion in extraction
and fixed incomes
Oil and Gas
Rapid development of POTENTIAL POLISH RESOURCES OF THE NATURAL GAS TRAPPED
shale gas IN SHALE ROCKS IS A GREAT CHANCE FOR THE ECONOMIC DEVELOPMENT

3. GAS RESOURCES IN SHALE ROCKS
Sweden
Poland:
UK
- Deep and saturated gas deposits
- Large area of exploration
But the deposits need VERIFICATION
Poland
Germany
Ukraine
Austria
France Hungary
Italy Romania
Bulgaria
Spain
Turkey
Algeria
POLAND MAY BE RICH IN GAS

4. Gas resources in Poland (Paleozoic, Silurian)
• GAS in BED ROCK
in 3 basins:
- the BALTIC basin (Sth Baltic)
- the Mazowiecki basin
- the Lubelski basin
• TALISMAN ENERGY together with
SAN LEON hold 3 concesions:
GDANSK
BRANIEWO
SZCZAWNO
• Possible economic and
social consequences:
- domestic gas consumption: 14
bcm/pa, where 4 bcm is
domestic production
- shale gas resources are
estimated on 1.4 – 5.0 tcm,
meaning over 300 years of
operation and energy
independence

5. THERE ARE STILL MANY UNCERTAINTIES ON GAS DEPOSITS IN POLAND
• Reported quantities are only ESTIMATED
• Lack of GEOLOGICAL data
• UNKNOWN TECHNICAL PARAMETERS OF GAS
• unknown COST-EFFECTIVENESS of EXTRACTION
DEPOSITS AND THEIR POSSIBLE EXPLOITATION REQUIRES STUDIES
5
6. WHAT IS THE UNCONVENTIONAL GAS ?
• Gas from shale rocks is a conventional gas
– methane contained in rockbed.
• Known for many years but only recently a
proper extraction technology was developed.
• the USA and Canada are leading in shale
gas production.
• Boreholes are 2-4 km deep.
Gas evaporates due to hydraulic fracturing.

8. SHALE GAS OPERATIONAL BOREHOLE
• State-of-the-art technologies
- horizontal drills (multiple at one site)
- minimalization of above-the-surface works
• Strict Quality Control:
- protecting the hole
- protecting the groundwater
- cement and steel casing
8
9. ENVIRONMENT PROTECTION – CANADIAN SPECIALTY
• Preparation of the work plan
• Selection of a drilling site
• Acquiring water for fracturing
• Controlling the process and minimalizing the
losses of water
• Components softening water - < 0,5%
• Reclamation and restoration of the area to the
original condition
• Complete safety for the people and nature
9
10. NATURAL ENVIRONMENT
• DRILL SITES ARE CAREFULLY SELECTED
- Outside the NATURA 2000 areas
- Distant from rivers and private houses
• DRILLING WELLS ARE CAREFULLY PROTECTED
- Thick steel pipe + cement
- Multilayered protection
10
11. GAS EXTRACTION– NATURAL PRODUCTION
NATURE PROTECTION IS THE BIGGEST
CHALLENGE FOR THE GAS INDUSTRY
• Gas production develops on the areas where
nature and its conservations is treated with
utmost attention (e.g. Montney Province
Alberta/British Columbia),
• As well as on populated areas where dense
network of settlements mixes with the areas
of nature preservation (e.g. Marcellus –
Pennsylvania, USA)
• The issue of water use in fracturing causes
popular upset because of the dim knowledge
about the process
• The industry developes technologies aimed
at minimalizing the pressure on the
environment
Delaware River

13. GAS PRODUCTION – UNDERGROUND, NOT ABOVE
THE GROUND
After disassembling all the drilling devices,
only a small control-survey valve
stays on the surface.
In its close vicinity people can live, rest,
have fun, crop and plant fruits, etc.
13
14. TALISMAN ENERGY – CANDIAN WAY OF CARING
ABOUT THE PEOPLE AND THE ENVIRONMENT
• Everywhere and everytime – dialogue with the communities and carefull
attention to their opinions
• CONSERVATION OF NATURE AND RESOURCES
• Keeping the Human – Environment balance
• We are dealing with subjects causing concerns:
- acquisition and use of water
- protection of the groundwater
- nature conservation – time and intensiveness of the drilling
- noise and road transport
- economic gains
GOOD NEIGHBOUR – CORPORATE RESPONSIBILITY PROGRAMME

15. IF WE SUCCEED ...
Successful studies, decisions on the extraction and production of gas will positively
influence the economic prosperity of the region and country (for example
Pennsylvania/USA):
• NEW WORK PLACES
(exploratios, studies, evaluation, contracts – geologists,
analysts, workers, managers, landowners)
• BUSINESS DEVELOPMENT (drilling, transport, ground and roadworks,
waste recycling, technologies – engineers,
roadmen, hotels)
• DEVELOPMENT IN TECHNOLOGIES
(up-to-date surveys and drilling equipment,
heads, gas compressors, transport pipelines,
new energy blocs, providing communities with gas)
• RISE IN THE INCOMES – COUNTRY AND MUNICIPALITY
WIDE
(licences, exploatation fees, local taxes, VAT, excise tax, land fees, rise in
consumption)

17. MAIN CONCLUSIONS FROM EXPLOATATION
The Can-Do-Spirit!
1. THE DRILLING SITE SHOULD BE CHOSEN CAREFULLY
(geology, nature, men, transport, future development)
2. PROPERLY MADE DRILLING IS SAFE
(survey, piping, casing, cementing, site, supervision)
3. FRACTURING IS SAFE FOR THE ENVIRONMENT
(water as a sand carrier, REACH, purification)
4. IT SHOULD BOND STANDARDS OF SECURITY, HUMAN AND
EQUIPMENT WORK
(norms, standards, law, sense, experience)
5. GOOD COLABORATION WITH LOCAL COMMUNITYS IS A
GUARANTY OF PROJECT STABILITY
(meetings, conversations, education, understanding, cooperation)
