President John Mahama has been challenged to set up a presidential enquiry into how the Energy Minister’s signature was allegedly forged by an international oil firm to lay claim over a piece of oil rich area in the Western Region.

New Patriotic Party (NPP) Minority Member on Parliament’s Mines and Energy Committee, William Owereko Aidoo, says the President must lead the process to resolve the mystery surrounding the issue.

The local subsidiary of Gondwana Oil Corporation in Ghana, Miura Petroleum Limited, is alleged to have made an estimated $1.5 million using a forged letter as a basis to sell off majority stake in the oil rich area to its parent company.

The parent company also used the letter as a basis to raise $40 million on the Canadian stock exchange.

Gondwana this week claimed in a letter to shareholders that energy ministry had agreed to pull down the allegation of forgery from its website.

Joy News checks reveal that the press statement on the allegation on the ministry's website had indeed been removed.

But the Ministry insists the removal of the statement was a coincidence and attributed it to routine maintenance of the site.

"There are so many aspects of this thing that make it murky. All these come together to put a big blot on Ghana's oil industry. How do you think the international investment community will be thinking about us?" he asked.

He said the situation could affect oil companies with genuine letters from government who are sourcing for funding from investors.

"It is incumbent on the president to do his utmost best to investigate this matter for all and sundry to know what is going on here and rebuild confidence in Ghana's oil industry", he said.

In a related development startling revelations are set to emerge in an internationally acclaimed documentary about Ghana’s Oil exploration and production in the coming week.

The Documentary titled “Big Men” will be premiered in Ghana from Wednesday after it received rave reviews in the United States early this year.

OXFAM Ghana and the Africa Centre of Energy Policy (ACEP) will be coordinating the Ghana release of the controversial documentary.
