Nicosia and Cairo have agreed to build a gas pipeline from the Aphrodite field in Block 12 to Egypt, but those reserves could remain untapped in a row over profits.
The deal could come unstuck if the government does not strike a compromise on profit sharing with the consortium licensed to exploit Block 12.
CyBC TV said the agreement, already approved by Brussels, is undergoing the finishing touches before it is signed at an official ceremony in the Autumn.
An Energy Ministry official has briefed the political parties on new demands by US firm Noble, UK-Dutch Shell and Israel’s Delek to exploit Aphrodite gas.
They want a change in the product-sharing contract which outlines the percentage of revenues to be received by the state in any commercial deal.
The three companies have proposed a ratio change of 60-40 in favour of the Republic of Cyprus be reversed so that Noble, Shell and Delek receive the lion’s share of the 60% instead.
Such a reversal in the profit ratio would see the state lose in the region of €2.5 bln to the consortium.
