Drilling Fluids Losses: LCM in Reservoir Section
If losses occur in reservoir sections, the following options are available:
As a first step, the mud gradient shall be reduced, formation pressures permitting.
If the gradient reduction provides no benefit, then use CaCo3 LCM material as follows:
Formulation and Mixing Procedure for LCM Pills
Calcium Carbonate shall be applied according to the details in the following table:
Loss Rate < 12 bbl/hr
Loss Rate 12 - 22 bbl/hr
