Eni proves more gas in presalt play offshore Congo

Offshore staff

SAN DONATO MILANESE, Italy – Eni has discovered potentially large volumes of gas and condensates with its latest exploration well offshore Congo.

Nkala Marine-1 was drilled in 38 m (124 ft) of water on the Marine XII block, 20 km (12.4 mi) offshore and 3 km (1.86 mi) from the company’s producing Nene Marine field. Eni estimates possible in-place reserves of 250-350 MMboe.

During a test, the well flowed more than 300,000 cu m/d of gas and associated condensates. There was a major gas and condensates build-up in the presalt clastic geological sequence of lower Cretaceous age, crossing a hydrocarbon column of 240 m (787 ft).

Eni plans further delineation wells, and the partners will undertake studies for a commercial development, taking in various oil and gas discoveries in the block.

The company estimates combined resources from these finds at around 5.8 Bboe. Production from the block started last December and is currently around 15,000 boe/d.

Eni Congo operates Marine XII in partnership with New Age and Congolese state company Societé Nationale des Pétroles du Congo (SNPC).
