Platts.  A consortium working on an Alaskan natural gas pipeline and LNG project will conduct a substantial field season to gather new geotechnical and environmental data in 2014, an ExxonMobil executive said Thursday.  The effort will put more than 300 people into the field, and is about twice the size of the 2013 summer field season, said Steve Butt, an ExxonMobil official who is also project manager for the consortium, which also includes BP, ExxonMobil and TransCanada.
