Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Well 9/2-A-4 is a development well on the Yme Field in the Norwegian Danish Basin. It was the third Sandnes Formation oil producer drilled on the Yme Gamma Vest structure.
Operations and results
Well 9/2-A-4 was spudded and drilled from slot 4 of the Yme template. The A-4 well was planned with an "S" shaped profile, in order to drill vertically through the upper Sandnes Formation in the northerly crestal area of the Gamma Vest structure, to the north of the A-4 slot and well A-8T2.
The Sandnes S12 target was penetrated at 4630.5 m (3162.8 m TVD RKB), approximately 2887.6 m north of the platform, at an inclination of 17.8 deg. It was oil-filled down to the OWC at 4720 m (3252 m TVD RKB). The well was drilled to TD at 4845 m (3377 m TVD RKB) in the Bryne Formation.
A total of 68 m cores were cut in three cores at 4635 to 4704.5 m in the Sandnes Formation.
Production
The well was produced from the intervals 4677.6 - 4679.2 m, 4667 - 4671.5 m, and 4643.9 - 4654.3 m in the in the Sandnes Formation.
