John is an Earth Sciences graduate who joined SSL in 1980 as a processing geophysicist in their borehole seismic division. He progressed to the position of VSP processing team leader in their UK head office and worked on the more complex data sets. John’s ability to understand how differing energy arrivals will appear in a VSP data set led to further promotion and a 30 month assignment as head of SSL’s VSP processing centre in Norway. This was followed by a second posting of similar length leading the SSL VSP processing centre in Australia before he was asked to return to head office to assume overall lead of VSP processing operations. In mid 1993 CGG became the owners of the SSL borehole division and John became manager of the whole of the resultant, enlarged, VSP group. John left CGG to return to a more technical position and is the lead geophysicist within Zebra Geosciences.
Sadly John passed away in 2016 but he will always be an integral part of Zebra Geosciences.
