Autry Stephens, Billionaire Oil Pioneer, Dies at 86

The founder of Endeavor Energy Resources, known for his work ethic and innovative drilling techniques, passed away after a prolonged illness.

Stephens launched Endeavor Energy in 1979, transforming it into a major U.S. oil and gas firm.
He was renowned for buying and developing challenging wells that larger companies avoided.
In February, Stephens agreed to sell Endeavor to Diamondback Energy for $26 billion.
His daughter, Lyndal Greth, will succeed him as chairman of the board.
Stephens' innovations in horizontal drilling significantly boosted U.S. oil production.
