Negative Location specific LL with Faroe

Brasse Appraisal (31/7-2 S) – Reservoir section

What happened:

WL logs showed that the core point was in the Hardråde fm in the Shetland Gp and not in the Draupne fm. As per plan.

The gamma ray showed a higher than anticipated value than expected for the Hardråde fm, but lower than expected for the Draupne fm. A decision was made to call core point as it was concluded better to start cutting core in Hardråde than starting to cut to deep.

What was planned:

Drill down to core point in the Draupne fm

What was learned:

The gamma ray reading in the lower Hardråde fm was observed to be higher than expected.

What actions are required:

Ensure to correlate expected gamma ray values in the Hardråde fm for future wells with the observed value from 31/7-2 S
