Miller Quarles, Jr. (1905-2010) was a former employee of Petty Geophysical and a Life Member of SEG. He was known as being a competent geophysicist, and one of the early interpreters who employed the Bright Spot method of direct hydrocarbon detection.[1] In his later life Mr. Quarles was known for his interest in life extension technologies.[2] [3] [4]

Miller was my boss and mentor
Prior to the Vietnam war, I had worked for Petty in Wyoming and California. When I
returned from Vietnam in 1970, I worked for Petty Geophysical in San Antonio, directly
under the tutelage of Miller. He was a very meticulous geophysical
interpreter, and developer/supporter of the Bright Spot theory. He developed the ESP technology (Extracted Seismic
Properties). I believe I owe quite a bit of my success in the Oil & Gas Industry to the time Miller took to teach me a
lot of what he knew. I feel privileged to have known and worked with him.
