Additional time was required to overcome the difficulties of squeezing salt, as well as a swelling clay section requiring the running of an extra casing interval. Weather conditions have also been extreme. Following further detailed analysis, Northern Petroleum Nederland (NPN) will be preparing and designing a testing and fracturing programme for those intervals interpreted as gas bearing.

Derek Musgrove, managing director of NPN, said: “Tiendeveen is situated in the east of the Netherlands and is 3.8km from our Geesbrug gas field and pipeline on the Drenthe III licence. If testing is successful Tiendeveen will be adding to our reserves and production from the Grolloo and Geesbrug fields. This clearly demonstrates the potential this region has to offer. With approximately 50% of Dutch daily energy needs being provided by natural gas, strong demand can be expected to continue.”

Northern’s partners in the well are NPN with 45%, EBN, the state oil company, and Dyas with 40% and 15% respectively.

NPN is Northern’s wholly owned subsidiary management company developing onshore oil and gas fields in The Netherlands.
