General

Well 2/4-19 B was drilled on the Ekofisk Field in the Southern North Sea.

Operations and results

Well 2/4-19 B was drilled from the Jacket 12 legs installation Ekofisk B. It was spudded on 16 December 1975 and drilled to TD at 4605 m in Jurassic age sediments. The hole was lost below 3926 m (the 7" casing shoe, in Early Cretaceous) after logging.

The well penetrated top Jurassic at 4061 m. The whole of the Jurassic section penetrated was mainly claystone, shale and limestone. Four cores were cut: core 1 from 2974 to 2992.5 m, core 2 from 3102.7 to 3113.8 m, and cores 3 and 4 from 3144.3 m to 3159.7 m. No wire line fluid samples were taken.

The well was plugged back to 3449 m and re-classed to development well. It was permanently abandoned 15 March 1976.

Testing

The well was tested from perforations at 3006.5 m to 3009.6 m in the Danian Ekofisk Formation. Bottom hole samples were taken, but no flow measurements were conducted. The DST temperature was 110 deg C, measured at 2840.7 m
