Working Interest
Mineral Rights & Energy Royalties
Definition
A working interest is an ownership interest in an oil, gas, or mineral project that bears a share of operating costs and receives a share of production revenue after burdens.
Why it matters
Working interests can offer direct commodity exposure and tax attributes, but the investor participates in operating cost, drilling, decline, environmental, and abandonment risk.
Common misconceptions
- •A working interest is not the same as a royalty interest; it usually carries cost responsibility.
- •High initial yield can fall quickly if production declines faster than expected or operating costs rise.
