This report is described about the progress of the drilling operations at the Yabase oil field which is the best one in Japan.
Since 1950, the drilling rigs have been unitized and the equipments and operations became systematic. We have now gained some results through our persistent efforts for three years.
We believe that we should make more efforts than ever before after re-examination of these results. By doing so, we hope we could obtain much more favourable results than in the past.
