Oil exploration started under the British colonial system and continued significantly after independence under Cheddi Jagan and Forbes Burnham until today.
Drilling and exploration works are in numerous places for about 100 years.
During the time when I was the Specialist Hydropower Engineer for the hydroelectric power works that were done in the Cuyuni, Mazaruni and other areas; Geologists from the Geological Survey Department, Guyana conducted separate and independent work in selected areas.
