TVOG                derives the majority of its revenue from oil and gas drilling and                development. TVOG primarily generates its own exploration prospects                from                its internal database, and also screens prospects from other geologists                and companies. TVOG generates these geological “plays” within a certain                geographic area of mutual interest. The prospect is then presented                to                potential co-venturers. The company deals with both accredited individual                investors and energy industry companies. TVOG serves as the operator                of                these co-ventures. TVOG operates both the oil and gas production                segment                and the drilling and development segment of our business                lines. |
