STOCKHOLM, Sweden – The jackup Rowan Viking has completed drilling and logging of an appraisal well on the Edvard Grieg field in the North Sea for operator Lundin Norway.
Well 6/1-23 S was drilled in 108 m (354 ft) of water in license PL338, 2.4 km (1.5 mi) southeast of the Edvard Grieg platform location.
Delineation was designed to help Lundin optimize the drainage strategy and determine the best location for production wells in this part of the field. The well also tested incremental resource potential.
It encountered a 66-m (216-ft) oil column in pebbly sandstone. Initial analysis of the acquired data looks promising in terms of additional in-place volumes.
Ashley Heppenstall, president and CEO of Lundin Petroleum, said results from this well and another appraisal well in the same area last year will likely lead to an upgrade of Edvard Grieg reserves.
“I believe that the southeastern part of Edvard Grieg contains material resource upside and that discoveries such as Luno II, together with the prospective resource potential from the Luno II North prospect could be commercially viable tieback fields to Edvard Grieg,” he said in Lundin’s latest results statement.
“As experienced with the Alvheim field development [also in the North Sea], the infrastructure of Edvard Grieg will in my view produce more hydrocarbons than is contained in the base Edvard Grieg plan of development.”
Rowan Viking now returns to the Edvard Grieg platform to continue drilling production and injection wells. Offshore hook-up and commissioning operations have started following installation of the topsides last month.
Lundin expects first oil from the pre-drilled wells during 4Q, with production building to a peak during mid-2016.
Elsewhere in the Norwegian sector, the company has relinquished licenses PL490, PL641, PL646, PL639, and PL546 and withdrawn from PL583. It has, however, assumed operatorship of PL533 west of its Alta oil discovery in the southern Barents Sea.
In July, Lundin agreed to take a 35% operating interest in PL758 and PL800 from EnQuest Norge, subject to approvals.
Production from the Alvheim field, operated by Det norske oljeselskap, has been below forecast due to maintenance work on one of the gas compressors on the Alvheim FPSO and the need to shut in two wells as a result of nearby infill drilling operations and well integrity issues.
Since completing a new infill well which came onstream in April, the semisubmersible Transocean Winner has worked-over the Alvheim KB3 well which re-started production, and the rig is now drilling a further multi-lateral infill well that should enter production in late 2015.
Another infill well will likely be drilled, coming online in mid-2016.
The partners have identified further infill opportunities on the Volund, one of numerous fields tied back to the FPSO, with at least one further well set to be drilled.
The third and final development well for the Bøyla field, which started production in January, has been drilled and completed and will be tied in soon.
Production from Lundin’s Brynhild field, connected to the Haewene Brim FPSO serving Shell’s Pierce field in the UK sector, has been below forecast. The third and final production well and one water injection well have been drilled and tied-in and are close to final commissioning.
The FPSO has encountered problems related to topsides efficiency and water handling constraints, although there has been some improvement in recent weeks. Output has also been impacted by a planned shut-in of the field during heavy-lift operations for subsea installations activities and a rig move.
In the Dutch North Sea, Lundin is a partner in the E17-A5 (WI 1.20%) development well, which came onstream in July.
