Ghana National Petroleum Corporation, (GNPC) has planned to use US$12.00 million to undertake a number of activities including the establishment of hydrocarbon accumulation in Voltaian Basin for the year ending 31st December 2019.

In the 2019, programme of activities of GNPC, it has made a budgetary allocation of US$12.00 million towards the execution of project like process 200 line km of 2D seismic data.

The rest are: Acquire 200 square km of 3D seismic data; Process 200 square km of 3D seismic data; Drill one (1) exploratory well; Undertake Environmental Impact Assessment; and  Continue the Community Engagement Programme.

The Voltaian Basin project in 2018 advanced into the data acquisition and processing phase with over 990 line km of 2D seismic data acquired out of which approximately 905 line km has been processed.

Preliminary result from reconnaissance-phased activities of the project has established a working petroleum system for the basin.

Consequently the project Will witness heightened exploration activity in 2019 towards determining basin prospectively.

According to history, onshore exploration activities continued during the First Republic (1957-1966).

Acting under the auspices of a Ghana-Soviet Union friendship pact, Soviet and Romanian Geoscientists explored for oil and gas in the Accra or Keta and Voltaian basins.

During this period, 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.

Today, the Voltaian Basin is an asymmetrical inland basin covering about 40% of Ghana’s continental landmass. It stretches into Togo, Benin and Burkina Faso.

Ghana has four sedimentary basins. These are the Cote d’Ivoire-Tano Basin (including Cape Three Points Sub-basin), the Saltpond Basin, the Accra/Keta Basin and the Inland Voltaian Basin.

The offshore basins cover about 60,000 km² (0-3500m water depth) extending from the Cote d’Ivoire-Ghana maritime border in the west to the Ghana-Togo maritime border in the east.

The onshore/coastal expressions of the Tano and Keta basins, respectively, located at the south-western and south-eastern corner of Ghana, have a total size of about 4,000 sq. km.

The Inland Voltaian basin is the largest sedimentary basin in Ghana. It occupies the central-eastern-northern part of Ghana. It is about 103,600 sq. km in size.

The Sedimentary basins are divided into quadrants of size one degree by one degree, equivalent to about 12, 420 sq. km.

Each quadrant is further divided into eighteen (18) blocks with each block size equal to about 690 sq. km.

  1. GNPC please kindly take notice of the voltain basin and any other activities you are currently embarking on because the Volta region is a trust territory which is in a union relationship with Ghana. The land is not part of Ghana lands. Take this advise to avert any resistance in the future.
