In the early 80s there was a company named Dorchester Gas. It carved out long lived low flow rate gas reserves mostly in the Oklahoma and Kansa Hugoton fields. It had an mlp form and was called Dorchester Hugoton Trust. About 4 or 5 years ago this merged with some private collections of oil and gas royalty and working interests, the most prominent being Spinnaker Resources. This was done as a diversifying angle for a couple of major owners/founders. These people were very straight shooters, so I hung around. The new company was named Dorchester Minerals and so it is today. Now it turns out that they have considerable mineral rights in the Bakken, so over the last few months the price has incresed considerably. Not today though!
I am not making any sort of recommendation. I did buy some less than a year ago below $20, but it is hard for me to buy a strong security.
My other MLPs are mostly GPs of gas pipelines, also MGG as you mentioned, and some Nustar GP which has a chairman who left Valero to run Nustar, sold his Valero stock, and invested millions in Nustar. Bill Greehey is his name, and he is the guy who more or less created Valero. But I have a loss in this one right now.
This is the sort of thing that tries your soul- there is every reason that Nustar (and MGG) should be a big winners over time, but also some more or less credible threats. The biggest I guess is the fear that the USA will permanently and meaningfully reduce it's use of liquid transportation fuels.
Overall, I have been very good at finding promising O&G investments, but way too often I have been flushed out early.
