I don’t like working interest. The operator can do a rework that cost hundreds of thousands of dollars and then you get a surprise bill. Sometimes the income is much less than the cost of maintenance. Working interest is risky. Royalty is the way to go.
Toby, I have been looking into Oil & Gas direct participation programs for my Roth Solo 401K. Limited partnership under leases seem like the best option. My primary goal are investment diversification and alternate streams of income.
