The company was formed by the merger in 2000 of two of the world's largest seismic contractors, Western Geophysical (founded in 1933)[2] and Geco-Prakla.

Schlumberger, owners of Geco-Prakla paid cash to Baker Hughes, which then owned Western, for a 70% stake in a joint venture of the combined companies.
