In page Spindletop:


Production at Spindletop began to decline rapidly after 1902, and the wells produced only 10,000 barrels per day (1,600 m3/d) by 1904.[2] On November 14, 1925, the Yount-Lee Oil Company brought in its McFaddin No. 2 at a depth of about 2,500 feet (800 m), sparking a second boom, which culminated in the field's peak production year of 1927, during which 21 million barrels (3.3 GL) were produced.[2] Over the ten years following the McFaddin discovery, more than 72 million barrels (11.4 GL) of oil were produced, mostly from the newer areas of the field.[citation needed] Spindletop continued as a productive source of oil until about 1936. It was then mined for sulfur from the 1950s to about 1975.[citation needed]
