"The Columbus management team recently spent some time in Trinidad reviewing the Steeldrum fields and have identified numerous opportunities to establish “quick-win” production growth through a programme of well optimisations, well reactivations and also some infill drilling activities, all to be funded from currently available resources. This would be in addition to our already announced activities at Goudron, Bonasse and Icacos. Further information on these planned activities will be announced in the near future. "
