Lira Offshore

Lukoil has completed drilling of the exploratory well Lira-1X and discovered a large gas field in the Lira structure in offshore Romania.

Lira is located at the Trident block (EX-30) in the deepsea.

Lukoil Overseas conducted exploration on the EX-30 block within the concession agreement with the Government of Romania of 2011.

At present, the company owns a 72% share in the project, with the remaining partners being PanAtlantic Petroleum with 18%, and Societatea Nationale de Gaze Naturale Romgaz with 10%.

The block is located at water depth between 300m and 1,200m, spread across an area of 1,006km².

The well is 170km from the coast, where the sea depth is 700m. It was drilled to a depth of 2,700m using the semi-submersible drilling rig TransOcean Development Driller II.

In a bid to further assess the Lira gas discovery, Lukoil said it temporarily abandoned the well.

"Seismic data revealed that the area of the field can reach up to 39km² and reserves can exceed 30 billion cubic metres of gas."

Based on preliminary results of the analysis of drilling data, Lira-1X is believed to have delivered a productive interval with a gas-saturated thickness of 46m.

Seismic data revealed that the area of the field can reach up to 39km² and reserves can exceed 30 billion cubic metres of gas.

Lukoil said that the Lira-1X well success will reduce the risk for further exploration on a series of prospective sites located close to the Lira structure, as well as in other parts of the block.

In 2016, the company plans to drill an exploration well at the Lira and reprocess seismic data to confirm the discovery size.
