SEISMIC CREW SURVEY—MARCH
Following a month of slightly increased activity, SEG’s March 1977 survey of oil companies and domestic contractors shows exploration in the U.S. and U.S. waters declined during the month. Slight decreases in crew activity were also noted during March in both 1976 and 1975 (Figure 1). The current total (282) represents a 17 percent increase from the figure reported for March 1976 (240). It is still 16 percent below the March 1975 total (299). Five contractors were operating 8 of the 226 land crews on a speculative basis. Comparative figures of U.S. land crews and marine vessels are given in Table 1. Seismic crew data for Canada are shown in Table 2.
