25/4-2 (Trine) is a discovery in the central part of the North Sea, five kilometres east of the Heimdal field. The water depth in the area is 120 metres. The discovery was proven in 1973. The reservoir contains oil in sandstone of Paleocene age in the Heimdal Formation, at a depth of 2,150 metres. Development concepts based on a coordinated development of 25/4-2 (Trine) and 25/5-9 (Trell) with subsea tie-back to the Alvheim field are being evaluated.
