MOSCOW – PJSC Lukoil says its Lira-1X exploratory well in the deepwater Romanian Black Sea has discovered a large, potentially extensive gas field.
The semisubmersible Transocean Development Driller II drilled the well on the Trident block (EX-30), 170 km (105 mi) offshore in 700 m (2,296 ft) water depth.
Romania’s government awarded the company’s subsidiary Lukoil Overseas Atash a 72% share of the 1,006-sq km (388-sq mi) concession in 2011, in partnership with PanAtlantic Petroleum and Societatea Nationale de Gaze Naturale Romgaz.
Drilling reached a depth of 2,700 m (8,858 ft) before the well was temporarily abandoned for further evaluation of the discovery.
Analysis of drilling data and geophysical exploration suggests Lira-1X delivered a productive interval with an effective gas-saturated thickness of 46 m (151 ft).
According to the seismic data, the field could extend up to 39 sq km (15 sq mi) in size, with potential for more than 30 bcm (1 tcf) of gas, although this has to be confirmed by appraisal drilling.
Lukoil adds that Lira-1X will reduce the risk for exploration on further substantial prospects nearby and in other parts of the block. Its planned work program for 2016 includes another well on Lira and reprocessing of seismic data to confirm the size of the discovery and precise assessment of its potential reserves.
