Norwegian Sea Sabina gas well confirms tieback potential

Harbour Energy has confirmed gas with an appraisal well on the Sabina discovery in the Norwegian Sea.

The Transocean Norge semisubmersible rig drilled the 6507/4-5 S well in 455 m of water, 270 km north of Kristiansund, in production license 211 CS.

According to a Norwegian Offshore Directorate update on Dec. 10, Harbour and co-licensees Petoro, Aker BP and Orlen are considering a tieback through existing infrastructure in the area.

The main goal was to delineate the gas/condensate discovery, originally made by Wintershall DEA (now owned by Harbour), in the Lange Formation and to perform formation testing.

In the main exploration target, the well encountered a 41-m gas column in sandstone rocks. In the secondary (Lysing Formation) target, the well penetrated a 30-m gas column in sandstone rocks.

The production test in the upper part of the Lange Formation flowed 530,000 cu. m of gas and 80 cu. m of condensate through a 28/64-inch nozzle opening.

The new estimates for the recoverable resources are 17 MMboe to 39 MMboe in the Lange Formation and 28 MMboe to 43 MMboe in the Lysing Formation.
