Prospects for growth in North Sea production this year are fading fast
Petroleum Intelligence Weekly, June 14 North Sea Production Struggles To Grow By Ronan Kavanagh in London
Prospects for growth in North Sea production this year are fading fast, with UK and Norwegian oil output through May already lagging last year's levels. At play is a combination of delayed new field start-ups, faster-than-expected decline rates at some older fields, and a series of technical problems resulting in unplanned shut-ins. This North Sea cocktail is expected to cap combined UK and Norwegian output at an average 5.57-million barrels a day in full-1999, just 44,000 b/d higher than last year, according to EIG estimates. On the other hand, combined production is expected to scrape above the 6-million b/d mark by the end of this year, compared with 5.76-million b/d at end-1998.
After an early peak of 5.62-million b/d in the first quarter of this year, UK and Norwegian output is expected to dip to 5.37-million b/d in the second quarter and 5.35-million b/d in the third quarter, owing to extensive summer platform maintenance. Output is expected to reach its nadir in June, dipping below the 5-million b/d mark, but should then rebound to just over 5.4-million b/d by August. After a second maintenance-related dip in September, the return of most platforms to normal operations and growing contributions from new fields should lift combined output to 5.95-million b/d in the fourth quarter.
Although average UK output is still expected to rise by almost 80,000 b/d this year, this expansion is not spread evenly among the major crude oil streams. While fields using offshore tanker loading are growing strongly, a steady decline is likely in Brent/Ninian and, to a lesser extent, Flotta flows. The notable exception to the trend is BP Amoco's Forties system, where production is expected to rise by nearly 9% to 940,000 b/d this year, on the back of rising contributions from new fields tied in late last year.
Summer Dip
The low point for UK production will come in June, when most offshore maintenance is planned. But with work programs also spread across July and August, production won't really begin to bounce back until September. Work in the UK is planned at Royal Dutch/Shell's Brent fields for around two weeks in June, and then another week in August. June work is also planned at other fields in the Brent system, including Shell's Auk and Cormorant, and Oryx's Hutton and Murchison. A further bunch of maintenance there is scheduled for September and, later, at the Dunlin, Osprey, Tern, and Eider fields. Summer maintenance is also planned at BP Amoco's Forties system and associated fields including Andrew/Cyrus, Brae, Nelson, and Scott. The Elf Aquitaine/Enterprise-operated Flotta system will see June work at the Piper and Saltire fields, while offshore loading fields have maintenance scheduled throughout the summer season.
The UK has experienced its share of operational problems so far this year, with production suspended at BHP's Liverpool Bay complex for almost all of April due to technical problems. Amerada Hess was also forced to take its Fife, Fergus, and Flora fields off-line at the end of April for an estimated three months of repairs to its production vessel. Prospects remain for further unplanned outages, as it will take time for the recovery in oil prices to translate into extra funds for pared-back operating budgets.
A series of new field start-ups should help boost UK production in the second half of the year, as output levels build up. These include Enterprise's 45,000 b/d Pierce, Kerr-McGee's 55,000 b/d Janice, and Conoco's 60,000 b/d Banff fields, all of which started up in the first quarter. Apart from a few small field start-ups expected over the course of the year, the next big project coming on stream is Amerada Hess's 83,000 b/d Bittern/Guillimot, in the fourth quarter.
Norwegian production should peak at just under 3.2-million b/d in the fourth quarter, thanks largely to contributions from fields that have already started up. These include Statoil's massive 227,000 b/d Asgard field and Norsk Hydro's 100,000 b/d Visund. They will be followed by Exxon's 80,000 b/d Jotun and Hydro's 100,000 b/d Troll C fields, both of which are expected on stream by the fourth quarter.
Norway's maturing crude oil streams are also feeling the pressure, with national production likely to fall short of official targets this year, and apparently on track for its second annual decline in a row. This means Norwegian producers are unlikely to have to turn down the taps to honor Oslo's commitment to cut output, to help Opec and other producers support oil prices.
Including these production cuts, Norway has set a new target of 3-million b/d for 1999. This excludes condensate production, which is expected to average around 210,000 b/d this year. But according to EIG estimates, crude oil output, excluding condensate, will come in as low as 2.77-million b/d this year.
Although satellite developments should help boost Gullfaks production by 18,000 b/d to an average 430,000 b/d this year, output from other streams is falling. Statfjord flows look set to fall by nearly 16% to 560,000 b/d, although this is due partly to a series of technical problems with production facilities, not just its aging reservoirs. Similarly, operational problems have held back Ekofisk production, despite an extensive revamp of facilities that was completed last year. Oseberg flows should rebound from maintenance this quarter, but are still lagging last year.
Platform maintenance in Norway is scheduled at Oseberg and Brage for 12 days in June, and at Njord for four days in July. Gullfaks will witness partial shutdowns for two weeks in September, and another two weeks in October, along with the Tordis field. Initial maintenance took place at Statfjord in late May and early June, and will be followed by a further two weeks of work from late August. Partial shutdowns at the Sleipner condensate field are planned for two weeks from the end of this month, and again in late August. |
