Here are two good websites providing information about shale plays all across the world, from the worldwide law firm Norton Rose Fulbright:
Its Hydraulic Fracking Blog gives commentary on legislation across the country affecting drilling and operations in shale plays.
Its Shale Gas Handbook explains how the technology works, and prospects for shale oil and gas development in countries from Europe to China.
Did you know that China is estimated to have the world’s largest shale gas reserves? That the United Kingdom may have as much as 5.3 trillion cubic feet of shale gas reserves? That in the US, US proved gas reserves have increased from approximately 323 TCF in 2012 to 354 TCF in 2013? All this and more can be found in Norton Rose’s Shale Gas Handbook.
