Paper Number: SPE-174260-MS
... filtration rate and solids/liquid invasion is based on enhanced pore plugging efficiency achieved by optimization of bridging agent's particle size distribution ( Abrams, 1977 and Vickers et al., 2006 ). However, the size ranges of solid drilling fluid additives, bridging and weighting agents, drilled...

... particles for pore sealing to minimize formation damage in two drill-in fluid applications. A grind-down effect was observed in case 1 (water based mud) which used 50 μm marble particles, and so steps were taken to restore the size distribution. There was no apparent attrition effect in case 2 (oil mud...
