Natural gas production from Norway's giant Troll field continued to be curtailed on Friday, as over-running annualmaintenance works on the asset further disrupted the planned summer schedule.
An update from offshore Norwegian network operator Gassco indicated that production availability will be reduced by 112.5 million cu m/d Friday and 100 million cu m/d Saturday, and will then resume the originally scheduled 43 millioncu m/d until 0400 GMT Tuesday.
Gassco said that Friday and Saturday's unavailability were "due to delayed startup." The asset had previously stopped production during a planned shutdown for annual maintenance in late-August, and is yet to properly enter the next phase of scheduled works.
The Norwegian continental shelf is currently at the height of its planned summer works, with additional field maintenance contributing to an aggregate production unavailability of 188.8 million cu m on Friday and 192 million cu m for Saturday. The weekend will see 149.6 million cu m of capability impacted.
Week 37 will see impacted production ranging between 107-121 million cu m/d, as well as the beginning of the UK's Easington Langeled receiving sub-terminal two-week annual works, which will close its maximum throughput capability of 72 million cu m/d for the duration.
Flows into the sub-terminal have already begun to fall back, with end-of-day nominations amounting to just 7 million cu m of receipts expected Friday.
Overall, the NCS is set to produce 155 million cu m Friday, with exit flows reflecting a short system at 169 million cu m/d.
The British NBP spot market rebounded in early trading Friday, with the Platts intraday assessment recording a 22.50 p/th valuation for within-day volumes, 22 p/th for the weekend contract, and 22.75 p/th for Monday's day ahead.
This brought the spot market to near parity with the Working Days Next Week (WDNW) contract, having previously been adrift at the beginning of the week on higher Easington receipts.
