1 Shale gas in Poland – prospects and challenges Marcin Lutyński Silesian University of Technology Gliwice, Poland U NCONVENTIONAL G AS & CO 2 S TORAGE L ABORATORY

2 - One of the biggest technical universities in Poland, - the University consists of fifteen faculties which offer about 50 courses and almost 200 specializations, -t he University employs 1863 scientific-didactic staff, including 173 titular professors and 237 doctors of science, - at present there are almost 29,000 students at the University. The Rectors insygnia

3 H istory: - the Silesian University of Technology was founded on 24th May 1945 with setting up of four faculties: Mechanical, Electrical, Metallurgical and Civil Engineering, - the first inauguration of the academic year at the University in Gliwice took place on 29th October 1945 and 2750 students began their studies, -so far, 114 thousand engineers have graduated from the University which has also granted 3,5 thousand PhD and 550 DSc degrees. A lecture at the Faculty of Electrical Engineering in the 1950s

4 International Cooperation: - the Silesian University of Technology participates in European programmes for academic exchange: - LLP-ERASMUS, - CEEPUS - Central European Exchange Program for University Studies, - STF – Scholarship and Training Fund, - CEI – Central European Initiative, - Support for the International Mobility of Researchers. A class at the Faculty of Architecture

5 Faculties: - Faculty of Architecture - Faculty of Automatic Control, Electronics and Computer Science - Faculty of Biomedical Engineering - Faculty of Civil Engineering - Faculty of Chemistry - Faculty of Electrical Engineering - Faculty of Mining and Geology - Faculty of Energy and Environmental Engineering - Faculty of Applied Mathematics - Faculty of Mechanical Engineering - Faculty of Materials Science and Metallurgy - Faculty of Organization and Management -Faculty of Transport -Foreign Language College -Institute of Physics – Centre for Science and Education The Silesian University of Technology gives an opportunity to develop in any field

6 Faculty of Mining and Geology: - employs 30 professors and PhD DSc holders and 113 PhD holders, -conducts research into modern mining technologies comprising geological prospecting, economically efficient extraction of mineral deposits, application of energy– efficient and reliable machines, compliance with all safety regulations and protection of the natural environment. Courses : -Mining and Geology -- Safety Engineering The main entrance to the building of the Faculty of Mining and Geology

7 Energy dependence rate of EU countries in 2008 The most important suppliers of crude oil and natural gas were Russia (33% of oil imports and 40% of gas imports) and Norway (16% and 23% respectively). Denmark is the only net energy exporter: -36,8%

8 Energy dependency rate, EU-27, All products Solid fuels Crude oil Natural gas

9 The new source? Unconventional Gas – Shale Gas Global spread in shale gas resources

10 Unconventional Gas… Whats that…? According to National Petroleum Council: natural gas that cannot be produced at economic flow rates nor in economic volumes of natural gas unless the well is stimulated by a large hydraulic fracture treatment, a horizontal wellbore, or by using multilateral wellbores or some other technique to expose more of the reservoir to the wellbore

11 Unconventional Gas Reservoirs deep gas tight gas gas-containing shales (SHALE GAS) coalbed methane (CBM) geopressurized zones Arctic and sub-sea hydrates

12 Unconventional Gas Resources Resources Pyramid

13 Conventional Gas reservoir Tight Gas reservoir Shale Gas reservoir Tightl Gas fracturing

14 Tight Gas This is gas that is stuck in a very tight formation underground, trapped in unusually impermeable, hard rock, or in a sandstone or limestone formation that is unusually impermeable and non-porous (tight sand) For example its appr. 21% of the total recoverable US Natural Gas reserves Conventional reservoir Tight gas formation

15 Shale Gas Reservoir characterization Low permeability reservoirs: md High organic content TOC > 1-6% wg. Shale is a source and sink for the gas Sorption of gas on organic matter in micro and nano pores Free gas in macropores and fractures In order to produce gas stimulation is needed, the most common method is hydraulic fracturing (slickwater) Injection of proppant in order to sustain fracture Low production rates ( – m 3 /well/day) but longer life of a well (up to 30 years) Horizontal wells provide higher recovery – 2 x more expensive

16 USA – the World leader in shale gas production Commercial production so far only in US and Canada In US Unconventional Gas (i.e. CBM + Shale Gas) accounts for 42% of the total gas production, in 2020 it should grow up to 64%) In Canada Unconventional Gas accounts for 24% of the total gas production

17 Two technologies that contributed to the development of shale gas reservoirs in the world 1.Hydraulic fracturing 2.Horizontal (directional) wellbores

18 Shale Gas Production principles

20 Fracturing of shale reservoirs Proppant Fracture

21 Hydraulic Fracturing Operation Equipment 1. Well head and frac tree with Goat Head 2. Flow line (for flowback & testing) 3. Sand separator for flowback 4. Flowback tanks 5. Line heaters 6. Flare stack 7. Pump trucks 8. Sand hogs 9. Sand trucks 10. Acid trucks 11. Frac additive trucks 12. Blender 13. Frac control and monitoring center 14. Fresh water impoundment 15. Fresh water supply pipeline 16. Extra tanks Production equipment 17. Line heaters 18. Separator-meter skid 19. Production manifold wg.

30 Challenges and prospects According to recent promises of the Minister of Environment shale gas production on commercial scale should start in 2014 Companies complain on formal obstacles EU Directives on shale gas?? There is a strong support of government regarding shale gas development – national research programme Blue Gas – 250 mln PLN ( ̴63 mln )
