C-36 A COMPELLING “CASE” FOR CHANGE – IMPREDO 4C-3D Abstract 1 In July 2002 a landmark 3D multi-component survey was recorded on a North Sea field by SeaBed Geophysical as part of the DEMO 2000 sponsored IMPREDO project. The recording systems deployed were the proprietary CASE (CAble-less SEismic) nodes: the result of over 5 years of research development and testing of 4C systems. A description of the system the outstanding operational success of the project and the subsequent conventional processing of the data are presented. Introduction A. MORTON E.W. BERG J.I.
