(Image source: jbdodane/Flickr)Eni has announced a new discovery of gas and condensates offshore Congo (Brazzaville) in the exploration prospect Nkala Marine, located in the Marine XII block

The new discovery lies about 20 km from the coast and 3 km from the Nene Marine field, which is already in production. The finding, realized through the Nkala Marine-1 well, is expected to hold a potential of 250-350 mboe. During the production test, the well provided over 300,000 cu/m per day of gas and associated condensates. It was drilled in a water depth of 38 m and encountered a major gas and condensates build-up in the pre-salt clastic geological sequence of lower Cretaceous age, crossing a hydrocarbon column of 240 m.

Eni will start the evaluation of Nkala Marine through new delineation wells. Together with its joint venture partners, the company will also start studies for its commercial development under the Marine XII permit.

Eni estimates oil and gas discoveries made in the pre-salt Marine XII block to yield approximately 5.8 bboe. Production from the block began last December currently stands at around 15,000 boe per day.

Eni is the operator of Marine XII block with a 65 per cent stake through its subsidiary Eni Congo. Other partners in the JV are New Age (25 per cent) and the Congolese state-owned Societé Nationale des Pétroles du Congo (10 per cent).
