Statoil finds more oil in North Sea Oseberg area
The semisubmersible Songa Delta has finished drilling two exploratory wells for Statoil in the Norwegian North Sea.
These were located 2 km (1.2 mi) south of the 30/11-9 A (Askja Øst) discovery, and 35 km (21.7 mi) southwest of the Oseberg Sør platform, in 110 m (361 ft) of water.
The main aim of well 30/11-12 S, according to theNorwegian Petroleum Directorate (NPD), was to prove petroleum in three sandstone layers in Mid-Jurassic reservoir rocks (the Tarbert formation).
It intersected a 37-m (121-ft) oil column in the upper part of the Tarbert formation, of which about 30 m (98 ft) exhibited good-moderate reservoir properties. Well 30/11-12 A, drilled farther down on the structure, encountered similar reservoir rocks but was dry.
NPD estimated recoverable reserves from the discovery well at 0.7-2.5 MMcmoe. It will likely be included in the evaluation of a new field development, along with previous finds in the area.
These were the twelfth and thirteenth wells on license PL 035, awarded under Norway’s 2nd licensing round in 1969.
NPD has authorized Statoil to drill two exploratory wells and one appraisal well in the block using the same rig. However, the appraisal well – 30/11-14 A – will only be drilled if a discovery is made.
