Maestro: Try $130,000 per inch mile, say a 16 inch line for maybe 200-300 mmscfd for 150 miles (don't know richness or compression) but ballpark is then 16 x 150 x 130,000 = $208 million, lay it in a season, ready to go say 2008-2009, i.e. consistent with plans for export via LNG and gas field developments by indies.
Good then for 20 years, based on GOM. Very economical way of delivering gas ashore, worthwhile when long term gas export now expected.
Stay the Course, even for gas
