In 1940, there were signs of a big oil field at Abqaiq and a major new discovery at Abu Hadriya. The drilling location for Abu Hadriya No. 1 had been partly based on seismographic evidence, a new development in exploration. When the well struck oil in March 1940, at twice the depth of Dammam No. 7, it was an early vindication for exploration geophysics. This significant strike also showed that similar deep geologic structures in Saudi Arabia might yield oil. In January 1944, when the company was renamed the Arabian American Oil Company, or Aramco, oil was critical for post-war industry, aviation and the recovery of wartorn Europe.
