Study On P-Wave Velocity And Mechanical Response Characteristic Of Rock In Coal Seam Roof With Supercritical Co2 Injection, Chen Chen, He Xingyi, Niu Qinghe, Yu Hongxu, Xie Xiangyu

Coal Geology & Exploration

Deep coal seam CO₂ geological sequestration and enhanced CH₄ recovery(CO₂-ECBM) can both increase CBM recovery and achieve carbon emission reduction, possessing dual benefits of energy and environment. The geochemical reactions between supercritical CO₂(ScCO₂), water and coal seam roof can change its physical-mechanical properties and increase the risk of CO₂ leakage. In this paper, taking the roof rock of No.3 coal seam in Hudi Mine from Qinshui Basin as the research area, the ScCO₂-water-rock geochemical reaction simulation experiment was carried out to explore the geochemical reaction process of ScCO_{2 …}

Developments In The Global Energy Markets And Constructing The Future Of The Persian Gulf Security, Nihat Cengel

Graduate Program in International Studies Theses & Dissertations

This study analyses the global energy projections and regional dynamics in the Persian Gulf. It is shown that the future projections in the world energy markets signify the importance of cooperation between developed and developing countries. It is also suggested that connected to the global economic crises and the regional demand change in the energy market, there is a growing need for international support to the Persian Gulf security.

I argue that the Gulf Cooperation Council (GCC) could play a crucial role for eliminating political conflicts and maintaining the regional stability. As a result, collective arm transfer to the region, …

Oil. Changing Geopolitics Of Oil In Asia & The Usa, Jay Hein, John Clark, Robert Ebel, Dong Hyung Cha, Richard Lotspeich

New England Journal of Public Policy

One of the most important responsibilities the United States assumed following World War II was ensuring the stable flow of relatively inexpensive oil to the industrialized and industrializing countries of the world. A glance at a list of the top petroleum exporting countries shows that most of them are poor, have despotic governments, and experience frequent bouts of political instability and ideological extremism.
