World demand for natural gas could grow by 3% a year over the next 15 years, with demand for liquefied natural gas (LNG) growing much faster, Executive Director Gas & Power of Shell Linda Cook reported at the SPE Technical Conference in Dallas. This will require massive investment. Innovative technology will be needed to maximise recovery from existing resources and lower the cost of developing new ones. Gaining access to resources will require adding real value for resource holders. With customers depending on gas delivered over increasing distances, demand for LNG - with costs continuing to be driven down - could expand threefold. But this investment must be choreographed along a complex value chain in dynamic markets.
