In 1976, Siebens Oil & Gas Ltd. acquired a substantial amount of 2D seismic data around the Yemeni island of Socotra and its neighbouring islands. The data was acquired by Seiscom Delta Ltd. and processed to final stack by Seiscom Ltd. A significant proportion of that data was reprocessed as final migrations by Seismograph Service (England) Ltd. in 1979. Canesis Data has vectorised a total of 3200 km of the data, of which 1100 km is in the reprocessed and migrated category (shown as yellow).
