The output from the hydraulic vibrators typically used for land seismic surveys is controlled by monitoring the acceleration measured by accelerometers mounted on the reaction mass and baseplate. The considerable energy output by such vibrators, whic

The use of pseudorandom sweeps (rather than the more conventional sweeps whose instantaneous frequency changes linearly) has received periodic attention over the past 45 years. In a previous article (Dean, 2014) I summarised the work published in thi

SUMMARY Seismic vibrators are the preferred sources for land vertical seismic profile (VSP) surveys as they are relatively repeatable, controllable, have high energy, have a low environmental impact, and are cost-effective. Unfortunately, due to the

SUMMARY Vibrators are the preferred sources for onshore vertical seismic profile (VSP) surveys. Truck-mounted units are especially useful as they are more road mobile than buggy-based units. In particular, they can be driven directly to the wellsite,

The use of pseudorandom sweeps has received periodic attention over the last 45 years. Previous testing has indicated that hydraulic vibrators may struggle to transmit such sweeps due to their rapid variation in instantaneous frequency and/or amplitu

Summary Due to the limited number of receivers employed, acquiring a vertical seismic profile is time consuming and is therefore often excluded from a logging job to save time. The combination of a fiber optic DVS recording system, a GPStime-based so

When a seismic hydraulic vibrator sweeps, it emits the signal we desire as well as a series of harmonics due to the non-linear behaviour of the hydraulic system and the baseplate-earth contact. The phase of the fundamental component of the transmitte

Hydraulic seismic vibrators are the preferred source for land vertical seismic profile (VSP) surveys. The introduction of new, more powerful vibrators wogether with the use of Maximum Displacement (MD) sweeps has resulted in the extension of the band

Two successive models of truck-mounted seismic vibrators were designed and manufactured to ensure the highest possible levels of vehicle safety while also delivering excellent data quality. Seismic vibrators are the preferred energy sources for land
