"Shale hidrokarbon masih menjadi salah satu topik hangat dalam industri perminyakan. Indonesia memiliki potensi shale gas yang cukup besar yaitu sekitar 574 TCF. Pemerintah bersama investor sedang memulai pengusahaan shale hidrokarbon. Parameter-parameter geokimia dan geomekanik merupakan aspek penting dalam eksplorasi potensi shale hidrokarbon dan memberikan informasi penting dalam rangka optimasi produksi. Namun demikian, masih cukup terbatas penelitian-penelitian terkait hubungan parameter-parameter petrofisik untuk shale hidrokarbon. Area penelitian berada pada bagian tepi selatan cekungan Sumatera Utara. Formasi Baong dipercaya sebagai target pengusahaan shale hidrokarbon dengan dominan litologi adalah shale. Formasi Baong berada pada kisaran kedalaman 1.465 - 3.224 m dengan mudstone tebal, didominasi oleh calcareous shale berwarna abu-abu coklat hingga hitam yang kaya foraminifera, mengindikasikan pengendapan pada lingkungan laut. Umur Formasi Baong bervariasi dari Miocen Bawah hingga Miocen Tengah dan secara vertikal dapat diklasifikasikan menjadi 3 unit, yaitu : Baong Bagian Atas, Baong Bagian Tengah dan Baong Bagian Bawah yang didominasi oleh shale. Penelitian ini bertujuan untuk mengidentifikasi potesni shale hidrokarbon dengan menganalisa Total Organic Carbon TOC, Brittleness Index BI, Hydrogen Index HI dan parameter-parameter kematangan. Berbagai metode dilakukan untuk menganalisa beberapa parameter tersebut, diantaranya dengan geokimia, mineralogi, petrofisik, cross plotting, dan interpretasi seismik. Hasil analisa Rock-Eval dan petrografi menunjukkan bahwa TOC bervariasi antara 0,1 - 2,3, vitrinite reflectance Ro berkisar 0,4 - 0,9, HI bervariasi antara 31 - 171 dan temperatur maksimum Tmax berkisar antara 432 - 461°C. TOC menunjukkan kategori cukup hingga baik. Crossplot antara HI dan Tmax pada diagram van Krevelen menunjukkan dominasi kerogen tipe II dan III. Kerogen dapat diklasifikasikan sebagai early mature hingga mature. BI pada shale termasuk pada kategori less brittle hingga brittle. Area prospektif untuk pengembangan shale hidrokarbon yaitu pada sekuen MFS-2, MFS-3, SB-2 dan SB-3 dengan potensi berupa shale oil.

Shale hydrocarbon remains one of the hot topics in the petroleum industry. Indonesia has a great potential shale gas resource 574 TCF, and both government and oil companies have promoted the development of shale gas. Geochemical and geomechanical parameters are important aspects for exploring new shale gas play, and it provides significant information to optimize production plan and stimulation design. However, there is limited research on correlations inter petrophysical parameters for shale hydrocarbon reservoirs. The study area is located on the southeast border of the North Sumatra Basin. Lower Baong Formation shales are believed to be favorable shale gas targets with a dominant shale lithology. The Baong Formation occurs at depths from 1.465 ndash 3.224 m in the study area with the thick mudstone, dominated by gray, brown to black calcareous shale rich in foraminifera, indicating a marine environment. The Baong Formation age varies from the Lower Miocene to Middle Miocene can split into three vertical units the Upper Baong, Middle Baong, and the dominantly shale Lower Baong.

This research is aimed to characterize and identify shale hydrocarbon by examining the Total Organic Carbon TOC, Brittleness Index BI, Hydrogen Index HI and maturity parameters. Various methods were used to analyze these parameters, including geochemistry, mineralogy, petrophysics, cross plotting, and seismic interpretation. Our analysis on Rock Eval and petrographic data shows that TOC varies between 0.1 ndash 2.3, vitrinite reflectance of 0.4 ndash 0.9, HI varies from 31 ndash 171, and maximum temperature Tmax from 432 ndash 461°C. TOC resulted in a poor to good category. A cross plot of the HI and Tmax in the van Krevelen diagram revealed the dominant kerogen types as II and III. The kerogen can be considered as early mature to mature. The BI of the shale formation of the research area is categorized in less brittle to brittle. The prospective areas for the development of shale hydrocarbon are the sequences of MFS 2, MFS 3, SB 2 and SB 3 with the potential of shale oil."

"Dangerous CO2 emissions, massive oil spills, dwindling supplies the problems with fossil fuels are driving a longoverdue reassessment of our nation's energy policies. U.S. Congressman Jerry McNerney, a renewable energy engineer and the first representative with expertise in energy independence, leads the way to change. In "Clean Energy Nation", he and journalist Martin Cheek make an impassioned argument for drastically reducing dependency on fossil fuels and developing sustainable, readily available energy sources solar, wind, biofuel, geothermal, and hydrogen-based power. Bringing together a rare combination of scientific knowledge, political savvy, and insightful journalism, the authors reveal the pros and cons of alternative energy sources and examine how our nation became addicted to fossil fuels in the first place. The book reads like the dramatic story it is, complete with dire projections about peak oil and grim scenarios of rising oceans! keen insights into policies and players that have stalled progress on climate change and favored big oil!and astute recommendations for building a clean energy economy and a prosperous, stable future."

"This book describes and assesses energy technologies, markets and future strategies, focusing on their capacity to produce, exchange, and use energy vectors. Special attention is given to the renewable energy resources available in different areas of the world and made exploitable by the integration of energy vectors in the global energy system. Clear definitions of energy vectors and energy systems are used as the basis for a complete explanation and assessment of up-to-date, available technologies for energy resources, transport and storage systems, conversion and use. The energy vectors scheme allows the potential realization of a worldwide sustainable energy system to fulfill global development expectations by minimizing both the impact on the environment, and the international political frictions for access to limited and concentrated resources."

"ABSTRACTThis paper investigates the enviromental and economic impacts of introducing CO2 taxation on carbon-based fuels using a detailed disaggregation of energy-economy-enviromental CGE model for Indonesia. The carbon tax has yet to beimplemented in Indonesia. However, this instrument has been considered in the ministry of finance report as one of the goverment's fiscal strategic framework to finance the country's action plan in commitments to reduce the GHG emissions. Suppose that the goverment levies the tax of Rp.100,000/ton CO2e under two possible revenue-recycling scenarios: the carbon tax revenue is recycled troght a reduction of labour income tax rate or an incrase of goverment spending on commodities. For comparison purpose, we also implement the non-compensated scenario of which the additional revenue from carbon tax is kept as goverment savings to run budget surplus. Overall, the results suggested that the carbon tax reduces the national emissions but adding more cost to the economy, resulting a fall in GDP. in term of income distribution, the carbon tax tends to be progressive in bth scenarios of revenue-recycling. However, when there is no compensating mechanism, the carbon tax tends to be reggresive - the poorer houshols carry a higher share of the carbon tax burden."
