California Owners on Spindletop

Spindletop — the field of the 1901 Lucas Gusher — has been producing for 125+ years. Many of today's mineral interests are owned by California residents who inherited them 5-6 generations deep from ancestors who held interests during the original 1901-1905 leasing rush. If you live in California and receive monthly royalty checks from a Texas operator on a Jefferson County / Gladys City Unit lease, this guide is for you.

What You Likely Own

California-resident heirs of Spindletop interests typically hold one or more of:

Producing royalty interest — your tract's contribution to the Gladys City Unit's monthly revenue

Non-producing mineral interest — fee mineral ownership in a tract currently outside active producing units

Overriding royalty interest (ORRI) — a royalty carved out of a working interest

Non-participating royalty interest (NPRI) — a royalty interest with no leasing or development rights
