Geophysical activity in explorations for petroleum on a global scale in 1954 was 6.3% lower than the record high of 1953. Notable increases in geophysical effort in Europe, the Middle East, and the Far East were not sufficient to overcome the very substantial decreases in the United States and Canada. The reduction occurred mainly in seismic operations, which decreased globally by 8.4%. Gravity activity was on the increase almost everywhere with the world-wide rise of 7.1%. Magnetic and miscellaneous other geophysical methods also showed moderate increases in the neighborhood of one percent.
