## Answer
Quick answer Spindletop has produced through four distinct eras over 125+ years: Lucas Gusher era (1901-1905, explosive cap-rock production), primary decline (1905-1925), deeper Miocene development (1925-1950), and Gladys City Unit waterflood (1950-present). Each era has different implications for current mineral interest valuations — most modern revenue comes from the Gladys City Unit framework's continuous Miocene production tail.
