N/A Mud LL with Wellesley

Carmen (35/10-10S) – Reservoir section

What happened:

Weighted up the mud by mixing in a heavier mud. The volume of heavier mud can partially compensate for 100 MT Barite required onboard.

---

What was planned:

To weight up mud by adding barite

---

What was learned:

Difficulties mixing in barite evenly, risk of plugging lines.

---

What actions are required:

Evaluate weighing up mud by mixing in heavier mud rather than adding barite. The volume of heavier mud can partially compensate for 100 MT Barite required onboard.
