  1. The Brazilian Network for Shale Gas The View of CenpetroProf. Ildo L. Sauer and Colombo C.G.Tassinari THE ROLE OF SHALE GAS CHANGING ENERGY FACTOR AND ENVIRONMENTAL/REGULATORY BARRIERS Anfiteatro Prof. Dr. Paulo Ribeiro de Arruda - USP August 2014 – São Paulo

  2. BLACK SHALES Organic-rich rocks with very low permeability Petroleum Rock Sources Shale gas is natural gas contained within shale sequences. Prof. Ildo Luís Sauer

  3. Conventional Oil and Gas Unconventional Oil and Gas 150°C, is modified for gas Prof. Ildo Luís Sauer

  4. HOW MUCH UNCONVENTIONAL GAS DOES BRAZIL HAVE? • RESOURCES: those which are potentially valuable, and for which reasonable prospects exist for eventual economic extraction (amount of gas in the shale). • RESERVES:thosewhichare valuable and legally and economically and technically feasible to extract (amount of gas that you might be able extract,technically and commercially recoverable). • We have an estimation of gas content in Brazilian black shales Prof. Ildo Luís Sauer

  5. Global shale gas basins, top reserve holders Prof. Ildo Luís Sauer

  6. World Shale Deposits Prof. Ildo Luís Sauer

  7. Sedimentary Basins with Potential for Shale Gas Amazonian Solimões Parnaiba Sergipe Alagoas Acre Parecis São Francisco Reconcavo Parana Prof. Ildo Luís Sauer

  8. ACCORDING ANP Petroleum, Natural Gas and Biofuels National Agency • Parnaíba Basin Shalelayers are locatedatdepthsof 1.600 - 2.500 m V = 64.000 (area) x 0,04 (average thickness) = 2.560 km3 Barnettshaleanalogy 1.196 km 3______ 30 TCF 2.560 km 3______ x TCF x = 64 TCF Prof. Ildo Luís Sauer

  20. Shale gas in US gas production, tcf per year Prof. Ildo Luís Sauer

  21. SHALE GAS COULD BE A VERY IMPORTANT RESOURCE IN THE BRAZILIAN ENERGY MATRIX IN THE FUTURE Unconventional gas could be a cleaner “bridge fuel” for the transition from coal / oil to renewable energy sources Prof. Ildo Luís Sauer

  22. ToproduceShaleGas • Acquire rights to drillsite • Acquire subsurface seismic data • Formulate development drilling plan • Permit wells and facilities • Drill wells **** and Fracking • Complete wells • Install facilities • Produce natural gas! Prof. Ildo Luís Sauer

  23. Toproduceshalegas • It isnecessaire “create a permeable reservoir” and high rates of gas production by using intensively stimulated horizontal wells • It is necessaire fracking operations: • Trucks deliver water and fracking chemicals to drilling site • Shale is fractured and the water/chemical mix is pumped in Prof. Ildo Luís Sauer

  24. FRACKING PROCESSES Prof. Ildo Luís Sauer

  25. OPPONENTS WARNmethanescapeduringthefracking • Fracking is anenvironmentaldisaster • Produceairandwaterpollution • Accelereof global climatechange Prof. Ildo Luís Sauer

  26. Environmental impacts – real or not? • Ground water contamination • Water use and disposal • Chemical handling and reporting • Air quality • Induced seismicity • It is not very well understood how is the behaviour of natural fractures and faults when submitted to sucessives fracking process Prof. Ildo Luís Sauer

  27. The Braziliangovernmentwascharged to establishmeasuresthatcanbetaken to reducetheenvironmentalimpactand to assurethesafetyofshalegasproduction The responsability for monitoringfall to governmentand to industryitself Sometimesleadingthepublicperceptionthatlobbystscouldinfluencepolices Prof. Ildo Luís Sauer
