After four straight months of increased activity, SEG's September survey of oil companies and domestic contractors shows exploration in the U.S. and U.S. waters declined during the month (Figure 1). Comparative figures for U.S. land crews and marine vessels are given in Table 1.
Preliminary seismic crew data from outside the U.S. were reported for the first time in September. The information in Table 2 was reported by the oil companies and contractors who provided the U.S. data. Additional data from other companies being surveyed will be announced as soon as it is available.
SEG's U.S. Seismic Crew Count is taken monthly for the Federal Energy Administration and is financed by a grant from the International Association of Geophysical Contractors.
