Norway-based OMV has completed drilling and testing of the Wisting Central II horizontal well in the Wisting field in the Barents Sea, 310km north of Hammerfest.

The fifth well in the production licence PL537, Wisting Central II was awarded to the company in the 20th licensing round in 2009.

Drilling of this appraisal well was aimed at confirming the potential of the discovery by proving the hydrocarbon presence in the Wisting Central South and Central West segments that are undrilled.

The objective was also to prove the technical concept of horizontal wells in a shallow reservoir located 250m below seabed.

OMV also carried out a well test, with flow rates reaching above 5,000boe/d.

OMV said that the Wisting Central II well is the shallowest horizontal offshore well drilled from a floating drilling facility and has a depth of 402m.

"OMV carried out a well test, with flow rates reaching above 5,000boe/d."

The well has a total length of 2,354m and its horizontal section measures 1,402m.

In addition to drilling, the company conducted advanced data collection and geo-steering through the entire horizontal phase.

The well was spudded using the semisubmersible rig Transocean Spitsbergen and will now be permanently plugged and abandoned.

OMV executive board member responsible for upstream Johann Pleininger said: "OMV is very satisfied with the well test results, which are promising.

"This well is an important milestone towards a future field development on Wisting."

OMV (Norge) operates the PL537 licence with a 25% interest. Other joint venture partners are Petoro (20%), Idemitsu (20%), Tullow (20%) and Statoil (15%).
