Summary:
P296 EXTENDED HIGH-FREQUENCY PROCESSING OF VIBRATOR VSP DATA Abstract A seismic vibrator is a nonlinear system and will as a rule generate energy at higher multiples of this frequency in addition to the signal at the intended frequency. We demonstrate that these normally notaccounted-for frequency components can be recovered as signal for vertical seismic profile (VSP) imaging provided the total raw waveforms are used in the deconvolution process. Dukhan Field The Dukhan field located on the west side of Qatar (Figure 1) was discovered in 1939 and was put on production in December 1949. There are currently three producing reservoirs—Arab
