Novus shares fall on drilling report at Laos SYDNEY, May 20 AAP - Shares in oil and gas concern Novus Petroleum Ltd fell as much as 7.6 per cent after a production report revealed interruptions to its drilling program in Laos. At 1536 AEST, Novus shares were down 18 cents at $2.70, having lost 22 cents earlier in the day. Novus said it is trying to remove junk from the hole of a well spudded at the Naxay prospect in Laos on April 13. "Preparations are currently underway to sidetrack the well past the junk," the company said in its weekly drilling report. The prospect is in the MON/SDC licence which covers 37,000 square kilometres of Laos and Naxay is 60 kilometres north east of the capital. "It is a high risk, high reward prospect because the geology of Laos is less well understood further south," Novus said. Novus has a 20 per cent stake in the project and one stock broker said success at Naxay is worth a $1.00 a share to Novus. He said the shares looked cheap at these levels.
