General
PL 146 is situated on the Hidra Terrace along the eastern margin of the Feda Graben, Southern North Sea. The first well, 2/4-14 (1988-89), penetrated an overpressuried reservoir, which was tested in an updip position by the well 2/4-16 / 2/4-16R. The latter well did not confirm the reservoir model. It was then concluded that the zone of main interest had to be situated in younger strata, preserved downdip to the east. Well 2/4-14 was sitting approximately at the pinch-out point of the untested wedge. Well 2/4-18 was drilled to test this model.
Operations and results
Well 2/4-18 was spudded with the semi-submersible installation Treasure Saga on 26 April 1993. A pilot hole was drilled to 622 m in Pliocene sediments (Nordland Group) before it had to be plugged due to hole stability problems.
No cores were cut and no wire line fluid samples taken.
