John Clarence Karcher, Ph.D.
John Clarence Karcher is
credited with developing new instrumentation and interpretation techniques
that made reflection seismology a practical and economical exploration
tool. Working for Geophysical Research Corporation, he successfully found
and mapped salt domes on the Gulf Coast. This led to the first offshore
use of seismic by Louisiana Land & Exploration Co. in 1928.
In 1933, Karcher and
Everett DeGoyler were the first to map the deepseated Old Ocean dome in
Texas, one of the largest discoveries of oil and gas condensate ever made
on the U. S. Gulf Coast.
