There are 4 gas and oil trust which have been excellent investments this past year. These trusts also spin off great dividends running from 7 to 12% per year.
These trusts can be bought and sold like stocks, SJT, PTF, PGH, PWI.

Those are all good ones though. I'm into a few spiders and Ishares in both production companies and drilling companies. All are doing well.
Some small ones that have leases in good areas that are starting to drill their holdings are doing very, very well. Risky as hell though.
