LONDON -- The Marram appraisal well in the East Irish Sea has proven gas in the eastern part of the field, according to Venture Production. The well, which was drilled by the jackup Ensco 92, reached a total measured depth of 2,020 ft (616 m) and encountered a gross gas column of 469 ft (143 m) within the Ormskirk Sandstone, the company says. Initial analysis of downhole samples indicates that the gas quality and GIIP volume is within the company’s pre-drill expectation range. Venture will now conduct a final evaluation and assess potential development options.

Venture also reports that the Andrea well 48/15b-10 well in the North Sea has confirmed gas bearing sands. The well was designed to test Leman sandstone. Cores are currently being taken to confirm reservoir quality, prior to drilling to total depth and well testing.

Andrea, which is located in the “A” field’s production hub, has the potential to be
Venture’s largest discovery to date -- the company’s pre-drill recoverable resource estimates are between 3 and 44 MMboe. Venture expects to confirm recoverable resources within two weeks.
