Yme field

Yme is an oil field in the Egersund basin area in the southern part of the North Sea. The water depth is 93 meters.

Original development by Statoil

The field was produced by Statoil from February 1996 to it was closed down in 2001. The field was produced using the jackup rig Maersk Giant equipped with oil producing facilities. The produced oil was transferred to the tanker Polysaga. Polysaga had a storage capacity of up to 160,000 cu meters of oil. It was moored and loaded by the subsea turret loading system (STL). The oil from Polysaga was offloaded to a shuttle tanker and transported to the Statoil Mongstad terminal near Bergen for final processing and fiscal metering. Mongstad had to beef up its desalters in order to be able to handle the Yme crude. The field was abandoned in a time of low oil prices after having produced 51 million barrels of oil (15% recovery of original oil in place).

Redevelopment by Talisman Energy

Now the field is to be redeveloped by Talisman Energy who will start producing early 2009. The Yme project will be redeveloped with 12 production and injection wells and a subsea storage tank. Talisman Energy hopes to recover a further 56 million barrels of oil over a periode of 10 years.

Crude oil quality

The crude oil produced had an API gravity of 38-39 and a sulfur content of 0.17% mass. The formation water had a high salt content with dissolved NaCl of 190.000 ppm. And there was a high asphaltene content in the crude oil.

The Yme reservoirs also had challenges such as low reservoir pressure and low dissolved gas content.
