Not much in Mosquero spot in the road.  There are already a few other CO2 lines been there for several years now go by here to Permian Basin Midland Odessa TX area.  I see these listed under pipelines in my NM phone book but nothing on Hess.  Might be part of the Bravo Dome or Rosebud area ?  Think Bravo use to be called Sheep Mountain.

Did you ever find out anything else?  Found this today looks like Bodell was involved and the compressor station was finished last year.  Maybe another one or some tie ins coming up?
