ABERDEEN, UK -- Venture Production has hit pay with well 49/4c-7z in block 49/4c in the North Sea. The well was intended to appraise the northern section of the Kew field. Venture has a 100% interest in the block, which lies 1.9 mi (3 km) east of its operated Chiswick platform and 8.6 mi (13.8 km) north of its operated Markham platform.

The well proved gas in the northern section of the field with gas found in the Silverpit, Leman, and primary Carboniferous reservoir. Cores have been taken to confirm that the Carboniferous reservoir quality is in line with expectations as indicated by logs, the company says.

Top Carboniferous came in 23 m (75 ft) high to prognosis and preliminary work indicates that the Carboniferous gas-in-place volume is higher than the pre-drill best technical case, but within the range of expected outcomes, the company says.

Final evaluation requires detailed analysis of the cores, which will be completed over the next few weeks. The well is planned to be suspended for use as a producer at a later date. The company is currently finalizing a field development plan using existing local infrastructure.

As well as confirming the development potential of the Kew discovery, the results of the well supports the planned drilling of the nearby Wandsworth Carboniferous exploration prospect, the company says. Venture holds a 100% interest in Wandsworth and plans to drill a well to test the prospect in 2010.

"Kew has delivered additional gas that we can tie-in to our existing infrastructure and development planning for this is ongoing," says Mike Wagstaff, chief executive of Venture. "We now look forward to a series of new wells in our equally important 'A' fields hub before returning to GMA later in the year to continue with the development of the Chiswick field."
