SHARES in Bowleven surged 9% after the company announced it had reached a keenly-awaited agreement to supply some of the gas it hopes to produce off Cameroon to a fertiliser maker.

Edinburgh-based Bowleven has signed a Memorandum of Understanding (MOU) with Germany's Ferrostaal under which it intends to supply gas for use in a fertiliser plant the company is building in the West African country.

Under the terms of the MOU, the plant is expected to provide a market for some of the output from Bowleven's Etinde Permit for at least 10 years, from 2015.

The signing of the MOU is a landmark event for Bowleven, which needs to raise funding for the costly infrastructure it will have to install before it can start commercial production off Cameroon. This will be partly dependent on persuading funders that there would be a market for any gas it produced as well as more valuable oil.

The MOU was also signed by SNH, Cameroon's state-owned oil and gas corporation.

Kevin Hart, chief executive of Bowleven, said: "Cameroon has a strong and growing domestic fertiliser market and we look forward to working closely with SNH and Ferrostaal to deliver the project.

"We are encouraged by the progress in our route towards the monetisation of Bowleven resources.

"This is a positive step towards the realisation of the potential of our acreage."

In a statement, SNH said that the signing of the MOU marks "a major step of this important project which is expected to speed up the agricultural revolution advocated by the head of state, His Excellency Paul Biya, as part of his policy of Major Accomplishments".

Bowleven did not give any indication of how much revenue it expects to generate from the proposed gas sales.

Shares in the company closed up 7.25p at 88p.
