Unable to deliver LCM pill to the thief zone
We have pumped numerous LCM pills with concentration of up to 300 ppb with CaCO3 of medium and coarse size and we never seem to have been able to deliver the CaCO3 into the thieve zone.
The majority of the CaCO3 would accumulate on the low side of the 8-½” hole with inclination from 73 deg to 83 deg.
Has anyone else experienced similar situations in the past? What would be the YP of the base fluid for LCM? How else would you keep the CaCO3 in the suspension and not let them come out of the filtrate?
