Abstract
Determining a seal weight of a sealing composition for sealing a selected seal width and using the seal weight to compare different sealing compositions for sealing efficiency. The seal weight is also to be used to directly determine the minimum concentration of a sealing composition in drilling fluid for a desired level of spurt loss control in order to prevent losing drilling fluid into a hydraulic fracture.
