Successful appraisal well and extended production test on Alta
Lundin Norway, operator of production licence 609, and its partners have just completed a successful appraisal well and production test on the Alta discovery on the Loppa High in the southern Barents Sea.
“I am incredibly proud of what we have achieved. This appraisal well, including the test production, is important for several reasons,” says Managing Director Kristin Færøvik in Lundin Norway. “In technical drilling terms, this is the first time that we as a company have drilled such a long, horizontal well in this very unique reservoir with karstified carbonates; this is also the first time this has been done on the Norwegian Shelf. We accomplished this through an excellent operation, without any safety or environmental incidents. And not least, after more than two months of extended production from the well, we have a much better understanding of the field’s production properties. And the results so far, are much better than expected.”
Appraisal well (7220/11-5) on the Loppa High is located approx. 4 km south of the original Alta discovery. This is the fifth well in total around the Alta discovery, which was made in October 2014. Just over two months of extended production is now complete, and this test confirms excellent to very good reservoir conditions. Data acquisition and sampling have been carried out, including production logging. Pressure data indicates the same pressure regime as in previous wells drilled on the discovery, and confirm good communication across the Alta structure.
The results from the appraisal wells are important with regard to the continuing work to map the east flank of the discovery. The resource estimate for the field will be updated in connection with the company’s 2018 reserve update in early 2019. The resource estimate for Alta is expected to increase, and the uncertainty will be reduced.
“Now we will assess the need for additional appraisal wells, and we want to propose to the partnership that we proceed with more detailed field development studies,” says Færøvik.
The license partners are DEA Norge and Idemitsu Petroleum Norge with 30 percent working interest each.
