Total this week started a production test of its Garantiana discovery, aiming to find out whether the North Sea find is large enough for a stand-alone development.
The French player spudded the appraisal well in production licence 554 in the end of May and started the production test on Tuesday, Martin Tiffen, outgoing head of the company’s Norwegian business, told Upstream.
Garantiana was found in 2012 and is currently estimated to hold between 25 million and 75 million barrels of oil, making a subsea tie-back the most likely development option.
"(There is) some infrastructure around, and we will probably be looking for a subsea development using some existing infrastructure - or in a very high case bringing in some kind of floating production system ourselves," said Tiffen.
Potential host facilities include the Statoil-operated Snorre and Visund platforms to the south, and BG Group’s Knarr FPSO to the north, all located within the same approximate distance to Garantiana, said Tiffen.
Before Total and partners Det Norske Oljeselskap, Spike Exploration and Svenska Petroleum can make any such decisions, though, the production test will have to be completed and the data analysed and evaluated.
"We will know more about where we are in a couple of weeks," said Tiffen.
