The distribution process for NG is a painfully slow one. Pipelines, the major distribution method in the US as of now have to be permitted. This process is very tedious, i.e.: years.
One interesting fact is that there are major LNG (liquefied natural gas)terminals built for IMPORTING LNG, now being retrofitted to EXPORT LNG. I believe there are at least 3 on the Louisiana coast being converted as we speak.
All I really know is that the Shale plays are getting easier i.e.: cheaper, to produce for oil and the major NG plays like HK are turning their attention to oil in the shale formations as well where even last year oil was just an afterthought.
