Oil and gas discovery near the Fram field in the North Sea – 35/11-23

11. november 2019

Idemitsu Petroleum Norge (15 %) with the operator Equinor Energy AS (45 %), ExxonMobil Exploration and Production Norway AS (25 %), and Neptune Energy Norge AS (15 %) have discovered oil and gas in exploration well Echino Sør, 35/11-23, next to the Fram field in production licence 090 in the North Sea.

The well has been drilled 3.2 kilometres southwest of the Fram field and 120 kilometres northwest of Bergen. The Operator has completed drilling of wildcat well 35/11-23 and is now drilling sidetrack 35/11-23 A to delineate the discovery.

The primary exploration target for the main well bore was to prove petroleum in the Upper Jurassic Sognefjord Formation. The secondary exploration target for the well was to prove petroleum in the Middle Jurassic Brent Group and to investigate the presence of reservoirs and reservoir quality in the Middle Jurassic Etive and Oseberg Formations.

In the primary exploration target, the well encountered two hydrocarbon-bearing sandstone intervals in the Sognefjord Formation. The uppermost interval has a combined oil and gas column of about 25 metres in sandstone with variable reservoir quality from good to extremely good. The gas/oil contact was encountered, while the oil/water contact was not encountered. The other interval has an oil column of about 15 metres in sandstone with good to very good reservoir quality. The oil/water contact was encountered.

In the secondary exploration target, the well encountered a total oil and gas column of about 35 metres in the Ness and Etive Formations, whereof 30 metres of sandstone with moderate to very good reservoir quality. The gas/oil and oil/water contacts were encountered.

There are also indications of hydrocarbons in a five-metre thick sandstone layer in the Viking Group in the Upper Jurassic directly over the Brent Group, which will be studied more closely.

The well was not formation-tested, but extensive volumes of data have been collected and samples have been taken. The licensees will consider tying the discovery into existing infrastructure in the Troll-Fram area, after completing the sidetrack 35/11-23 A.

This is the 16th exploration well in production licence 090. The licence was awarded in the 8th licensing round in 1984. Idemitsu Petroleum Norge acquired the 15% shares from Petoro AS in 2002.

Idemitsu Petroleum Norge is very satisfied with the result of the Echino Sør well, a prospect that has been matured for a long time within Idemitsu, especially the positive result at the Brent Formation level. The discovery demonstrates that there is still very good low cost resources with low CO2 intensity to be found near infrastructure at the Fram field,” says Hiroshi Arikawa, Managing Director for Idemitsu Petroleum Norge.
