What happened in Reservoir section:
1” flowmeter hose burst causing spillage of OBM in the cement unit, while bleeding off during the XLOT dummy test. The reason the hose burst is probably that the OBM was too viscous and gelled causing it to plug up due to such a small diameter hose.

What Was Planned

Bleeding of through flow meter during XLOT

What Was Learned

Changed the 1” hose to a 2” hose giving more room for flow.

What Actions Are Required

Use 2” flowmeter hose and higher rated hoses. As the flowmeter used was a new type, it could also be wise to use consider the old one in future planning.
