The synchronized electromagnetic impulsive source

Abstract

Land seismic acquisition can be challenging, even in the best conditions and terrains. When the terrain changes from rural fields to industrial, urban, or environmentally sensitive areas, the challenges become more significant. A major factor that influences the difficulty and cost of seismic acquisition is the seismic source.

“…Geokinetics' synchronized electronic impulsive source (SEIS) system (also known as onSeis or electromagnetic thumper) (Pramik, 2011;Pramik and Bell, 2011) is about the same size as modern AWD units. The SEIS unit is quite special because it is based on weight lifted by an electromagnetic force rather than weight dropped (Pesa News Resources, 2010).…”
