UnconventionalGas & CO2 Storage Laboratory Shale gas in Poland – prospects and challenges Marcin Lutyński SilesianUniversityof Technology Gliwice, Poland
One of the biggest technical universities in Poland, the University consists of fifteen faculties which offer about 50 courses and almost 200 specializations, -the 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 Rector’s insygnia
History: • 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
International Cooperation: - the Silesian University of Technology participates in Europeanprogrammes 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
The Silesian University of Technology gives an opportunity to develop in any field 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 main entrance to the building of the Faculty of Mining and Geology • Courses: • Mining and Geology • - Safety Engineering 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.
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%
The new source? Unconventional Gas – Shale GasGlobal spread in shale gas resources
Unconventional Gas…What’s 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”
Unconventional Gas Reservoirs • deep gas • tight gas • gas-containing shales (SHALE GAS) • coalbed methane (CBM) • geopressurized zones • Arctic and sub-sea hydrates
Unconventional Gas Resources Resources Pyramid
Tight Gas reservoir Conventional Gas reservoir Tightl Gas fracturing Shale Gas reservoir
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 it’s appr. 21% of the total recoverable US Natural Gas reserves Conventional reservoir Tight gas formation
Shale GasReservoir characterization • Low permeability reservoirs: 0.0001 - 0.01 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 (15 000 – 140 000 m3/well/day) but longer life of a well (up to 30 years) • Horizontal wells provide higher recovery – 2 x more expensive
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
Two technologies that contributed to the development of shale gas reservoirs in the world • Hydraulicfracturing • Horizontal (directional) wellbores

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 €)
