<strong>Field</strong> Staffa Redevelopment<br />
Area Northern North Sea<br />
Operator Fairfield<br />
<strong>Development</strong> c<strong>on</strong>cept Subsea<br />
Transport c<strong>on</strong>cept 10 km pipeline to Ninian Southern?<br />
Start-up 2011/12<br />
Comments: The Staffa oil field has been relicensed to Fairfield which plans to redevelop it<br />
almost certainly by means of a subsea tieback rather than with an FPSO. Discussi<strong>on</strong>s have<br />
been held with three potential hosts. The c<strong>on</strong>cept is due to be decided and sancti<strong>on</strong> given by<br />
mid year. The closest platform is CNR’s Ninian Southern, at 10 km, which was Staffa’s original<br />
host. Total’s Alwyn platform is 15 km distant. Staffa’s original producing life was cut short when<br />
the pipeline was twice blocked by wax, asphaltene and emulsi<strong>on</strong>s. Fairfield has c<strong>on</strong>ducted flow<br />
assurance studies and is c<strong>on</strong>fident it can deal with potential blockages by pipeline insulati<strong>on</strong>.<br />
Start-up looks likely in 2011 or 2012.<br />
<strong>Field</strong> Stella/Harrier/Hurricane<br />
Area Central North Sea<br />
Operator Ithaca<br />
<strong>Development</strong> c<strong>on</strong>cept Platform or subsea centre plus subsea tiebacks<br />
Transport c<strong>on</strong>cept 10km pipelines from Harrier and Hurricane to Stella<br />
Export pipelines from Stella to?<br />
Start-up 2012/13<br />
Comments: In Apr Ithaca announced that it had successfully tested its appraisal well <strong>on</strong> the<br />
Stella HP/HT gas/c<strong>on</strong>densate discovery in block 30/6a which flowed 2,850b/d; estimated<br />
reserves have been significantly increased – the pre-drilling reserves estimate was 18m boe.<br />
Prior to the well Ithaca already c<strong>on</strong>sidered the field to be commercial. In late Apr it was<br />
preparing to drill a sidetrack, after which it would press ahead with development, it said. Ithaca<br />
has two HP/HT satellites lined up for tieback to Stella – Harrier (23m boe) to the south in 30/6<br />
and Hurricane (4.9m boe) to the west in 29/10b. Of possible hosts, C<strong>on</strong>ocoPhillips’ Judy<br />
platform lies about 20 km to the south-east and Total’s Elgin about 25 km to the north-west.<br />
But neither may have ullage for several years, so Ithaca may have to provide its own<br />
producti<strong>on</strong> facility, such as a jackup platform, presumably <strong>on</strong> a leased basis.<br />
