Joiner and former
druggist, physician, and amateur geologist
A. D. Lloyd (his original name was Joseph Idelbert Durham) teamed up to drill two test wells, barely missing out on discovering the Seminole and Cement oil fields. Joiner then
commuted to Rusk County from 1921 to 1925, before moving to
Dallas, Texas, in 1925, where he focused on selling some of his Rusk County leases to recent widows. On 11 August 1925, Joiner obtained a lease on widow Daisy Bradford's 975.5 acre farm, and moved to Rusk County proper in 1926.
East Texas Oil Field In 1927, A. D. "Doc" Lloyd convinced Joiner to drill for oil in
East Texas, predicting a well would encounter the
Woodbine at a depth of . Joiner mailed out a prospectus written by Lloyd to seek financing for his
wildcatting. After collecting enough financial backing, Joiner began drilling in Rusk County. Joiner and his crew drilled for three years beginning in 1927 with rusted, third-hand equipment. At one point, the
Texas Company geologist Walter R. Smith visited and joked, "I'll drink every barrel of oil you get out of that hole." Despite the opposition, Joiner was convinced of the possibility of oil in Rusk County. Other wildcatters who drilled near the narrow but long East Texas field included
Michael Late Benedum and
Joe Trees, part of the
Pittsburgh oil establishment, and
Clem S. Clarke, an oilman and
Republican politician from
Shreveport, Louisiana. Beginning in 1930, Joiner began to drill eight miles west of
Henderson, Texas, on the farm of Daisy Bradford. Using a flimsy pine rig and battered tools, his first two wells were unsuccessful. Eventually, at 8 p.m. on October 3, 1930, the Daisy Bradford Number 3 struck oil. The ensuing gusher sent the area into a frenzy. Joiner and Lloyd had discovered the East Texas field, the largest
petroleum deposit yet found at that time. Based in five counties, it was centered about western
Rusk County. Yet, Joiner had oversold interest in all three wells he drilled on the Daisy Bradford farm, and later sold everything for $1.335 million to
