The Statoil-contracted drilling rig Songa Trym encountered a minor oil discovery while drilling wildcat well 35/11-17 located approximately 1 kilometer south of the Fram field in the North Sea.
The Norwegian Petroleum Directorate notes “the well’s primary exploration target was to prove petroleum in Middle Jurassic reservoir rocks (the Brent group). The secondary target was to prove petroleum in Middle Jurassic reservoir rocks (the Fensfjord formation).”
Approximately 1 to 3 million cubic meters of recoverable oil equivalents were discovered from the following:
- A 48-meter gross oil column in the Brent group, 10 metres of which has good reservoir quality in the Etive and Rannoch formations.
- A 38-meter gross oil column was encountered in the Fensfjord formation, 20 metres of which has good reservoir quality.
- An approximate 10-meter oil column encountered in Lower Jurassic reservoir rocks (the Oseberg formation) with good reservoir quality.
The well was drilled to a TVD of 2889 meters in 357 meters of water depth and will be permanently plugged and abandoned.
Next up for the Songa Trym is the drilling of Statoil’s production well 35/11-A-31 in the same production license.
