Oil giant BP would not be drawn this morning on reports it could quadruple the size of its $5bn Indonesian gas plant.Bloomberg news reported that the fourfold expansion in the Tangguh liquified natural gas plant (LNG) was under consideration to take advantage of future growth in Asian economies.The move would form part of chief executive Robert Dudley's plan to replicate multibillion-dollar projects made by Royal Dutch Shell Plc that could generate long term cash and profits and fund growth in other areas, Bloomberg said.Speculation mounted after Gde Pradnyana, a spokesman for the Indonesian energy regulator, said space was being prepared for eight trains - industry jargon for production lines - at Tangguh.There are currently two trains for LNG at Tangguh."You can speculate there are still a lot more reserves to be discovered," Pradnyana said.A BP spokesman said there were no current plans to quadruple capacity but added it was "looking at the potential" for the site."In the phase we are at we have two trains up and running at the moment and we are making good progress towards a third train," he said.mm
