Risks and Uncertainties [Abstract]
Significant Customers	SIGNIFICANT CUSTOMERSThe Partnership leases mineral interests to exploration and production companies and participates in non-operated working interests when economic conditions are favorable. XTO Energy represented approximately 18%, 15%, and 21% of total oil and natural gas revenue for the years ended December 31, 2019, 2018, and 2017. If the Partnership lost a significant customer, such loss could impact revenue derived from its mineral and royalty interests and working interests. The loss of any single customer is mitigated by the Partnership’s diversified customer base.
