Dear All,

We have done a 9-5/8" casing cement job where the shoe is at 2788m. CBL shows very poor cement behind the casing all the way down from surface.


Drilling out shoe track shows a medium to hard cement. CBL/VDL has been done 4 days after cement job.

Cement was blended with microsilica for better strength.

Any idea is for this issue is highly appreciated.

thanks
