Ghana will revoke four petroleum exploration licenses from companies that are not developing the assets, the country’s deputy minister for petroleum said Nov. 6.

Mohammed Amin Adam told journalists in Cape Town that the country will take aggressive action to ensure that its petroleum assets are developed. The licenses were identified for termination after a review of 14 license awards that were made in recent years.

“Four of them are lined up for termination,” he said.

The government has not yet notified the companies involved.
