The Candeias Oil Well (C-1), discovered on December 13, 1941, is located in the municipality of Cande[1]ias, in the interior of the state of Bahia.[2][3]
Context and discovery
Drilled on June 30, 1941, the Candeias Oil Well 1 (C-1) was the first commercial exploration well and the first oil field in Brazil.[4][5] Previously, on January 21, 1939, a well had been discovered in Lobato, a district of Salvador, but it was not commercially exploited. Both used the same drilling machine. Work began on April 2, 1941, but drilling only took place in June and was completed on December 31, 1941.[6]
