Section N/A. What happened:
Done as per plan. For the coring operations a new LCM pill was mixed. The LCM from the 8 1/2″ drilling was to coarse for the coring run (limitation of 1000 microns through coring assy).

What Was Planned

To mix a new LCM pill for the coring operation.

What Was Learned

Mud engineer informed that the coarse particles can be added close to pumping the LCM into well. Its potential in saving LCM chemical by not adding the coarse particles before its known that LCM is required. It can then suitable for different BHA’s.

What Actions Are Required

Evaluate not to add the coarse material into the LCM prior to LCM required to be pumped to make it suitable for different BHA’s.
