Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 30/12-2 (Nipa) is situated on the Bjørgvin Arch north of the Utsira High in the NOAKA area NE of the 25/2-18 S Langfjellet discovery. The primary objective of the well was to determine the presence of hydrocarbons in the primary target Middle Jurassic Tarbert sandstones. The secondary objective was to evaluate the underlying Middle Jurassic Ness Formation sandstones.
Operations and results
The well was entered with the Deepsea Stavanger semi-submersible drilling unit on 14 August 2019 and drilled vertically to TD at 3203 m (3202.6 m TVD) in the Middle Jurassic Ness Formation. The well was drilled down to 186 m with seawater and hi-vis pills, from 186 to 1402 m with seawater and hi-vis sweeps, from 1402 to 2953 m with water-based mud and from 2953 to TD with BaraHib Eco water-based mud. The drilling went as planned.
The well encountered both Tarbert and Ness Formation sandstones. Tarbert Formation was penetrated at 3040 m (3009.6 TVD MSL) and consists of sandstone with coal seams and claystone stringers. The Ness Formation was penetrated at 3137 m (3106.6 m TVD MSL) and consists of sandstone, siltstone, claystone, and coal seams. A total of 163 m TVD (gross) of reservoir quality sandstone across Tarbert and Ness Formation sandstones was encountered but determined from LWD logs to be water bearing with no residual HC. LWD formation pressure pre-tests indicated water gradient for the saturation fluid which corroborated the log interpretation. No coring, no wireline logging, an
