Vibroseis Hardwire Similarity Tests Results Trend and Signal Strengths from Upper Benue Trough to the Chad Basin Areas, Lithologic Significance

Abstract: Hardwire similarity tests are conducted to verify integrity and performance of the vibrators component machines. It will certainly reveal to what extent it performs optimally. Many source parameters were recorded, which included, varying sweep range, dwell, drag length, number of sweeps, sweep lengths, peak force, boost or gain percentages and number of vibrators. Thus vibrator testing requires a significant amount of time in the field. Hard-wire test uses a cable connected from the Instrument recorder to the vibrator. It is an important performance check. The test is usually carried out at the start of the job and any other time the equipment is pulled for maintenance and repair. Besides, it provides for the integrity analysis check necessary to have a field processing system that will allow a geophysicist to make on the spot decision about further testing that may be necessary beyond the initial test lists. The sweeps and frequency bandwidth that characterize the Upper Benue-Chad Basin axis, have confirmatory identical signatures with stack section from the Doba Formation of SW to central South of Chad Republic.
