Royal Dutch Shell PLC (RDSA) is actively looking at ways to improve the profits it gets from U.S. natural gas, including seeking land for potential liquefaction and export terminals.

The Anglo-Dutch energy giant has invested heavily in
U.S. shale gas assets, but depressed local gas prices risk driving up the costs of its projects there.

Chief Financial Officer Simon Henry said Shell was examining plans to develop the gas into products that are more closely linked to oil prices, such as liquefied natural gas for export and gas-to-liquids technology that turns gas into a transport fuel.

He said Shell was even seeking out land to build possible sites to build the types of facilities needed but cautioned that at a cost of "around $5 billion to $10 billion a project, we have to be selective."
