WB : With current reserves-to-production ration standing at 35 years, Bangladesh could easily earmark 2 TCF natural gas for exports that could fetch at least US$200 million a year beginning in 2005 according to a World Bank assessment. The Bank's economist Dr Zaidi Sattar in a paper said the gas sector with nearly 13 trillion cubic feet (TCF) of proven and recoverable gas reserve, has already drawn in excess of $400 million of FDI on gas exploration and development.
