A number of wells originally operated by SAGA are located in this\r\narea on the Hidra Terrace, in the transition zone between the Hidra\r\nHigh-Steinbit Terrace to the NE, and the Feda Graben to the SW. The structural\r\nelements are separated by large NW-SE striking normal fault systems, forming\r\nseries of rotated and downstepping terraces towards the axis of the Central\r\nGraben. The main objective of well was to test the reservoir potential of the\r\nLate Jurassic in a down-dip position with respect to previous wells 2/4-14 and\r\n2/4-16. Secondary prospects were to be evaluated in the Late and Early\r\nCretaceous.

Drilling went without\r\nsignificant technical problems and close to the planned time schedule.

The uppermost part was characteristically containing tuffaceous claystones.\r\nThe middle part was dominated by claystones with traces of limestone/dolomite,\r\nwhereas limestones and marls dominated the lower part.
