How to record an investment in a joint venture?

I am single member LLC. My LLC invested in a small percentage of an oil well joint venture. I have set up a Fixed Asset, Depletable to account for the initial investments.

How should the incoming monthly distributions be categorized?

Example:

LLC paid the managing JV $5K in August for a working interest.

Each month, the JV sends a distribution payment depending on how the oil wells perform...let's say $200 distribution back to the LLC in September.
