While the former was first used on production well sites in the late 1940s‚ the latter was invented in 1947 by Floyd Farris and J.B. Clark. However even with these technologies being available as early as the 1940s‚ the first real commercially repeatable systems was used in the 1990’s‚ pioneered by
