Karl Twitchell

Karl Twitchell (d. 1968) was an American mining engineer.
Twitchell worked for Charles Richard Crane, investigating water potential of Yemen. Crane then employed Twitchell to investigate the water prospects in Ibn Saud's Saudi Arabia. In April 1933, Twitchell determined no prospects for an artesian aquifer existed beneath the desert. After oil was discovered in Bahrain, Twitchell became Ibn Saud's agent in the United States, tasked with generating interest in a Saudi oil concession. In the United States, Socal retained Twitchell as a negotiator, and on 29 May 1933, Socal received such a concession.
