Hi,
In the past year, investors have lost $20 billion in publicly traded drilling partnerships, or $8 of every $10 they had invested, according to a report prepared by FactSet for The Associated Press. That figure does not include losses from $37 billion of bonds sold by the partnerships in the five years since 2010, many down by half in last 12 months, or losses from bets on private partnerships that don't trade publicly and are difficult to track.
