Charles Fairbank

Leo Ranney born in 1884 was a geologist and engineer who pioneered the idea of horizontal drilling. The poster is a reproduction of an article published in Fortune Magazine in September 1947.  The concept was applied in the Province of Ontario in 1985 when a shaft was sunk into a small shallow oilfield near Sarnia, Ontario,  Now horizontal drilling is a common practice in the oil industry.
