PHASE 2 (1958 – 1966)
During this period, onshore exploration activities continued. Two more wells were drilled by Gulf Oil in the onshore Tano Basin as a continuation of their Exploration Programme carried over from Phase 1.
Apart from well logs, there is very little information on these wells.
Similarly, these Gulf Oil wells were drilled without seismic data.
Acting under the auspices of a Ghana – Soviet Union friendship pact, Soviet and Romanian Geoscientists explored for oil and gas in the Accra/Keta basin.
During the period also, the Soviet team drilling for water in the onshore Voltaian basin encountered traces of oil and gas in some of the boreholes in some areas in the Northern and Upper East regions. However, no major oil or gas discoveries had been made up to this time.
