CHARACTERIZATION AND REMOVAL OF FILTER CAKE

Haaland et al. (1976) compared hematite, ilmenite and FER-O-BAR with barite (Table 1). The specific gravity of iron oxide is higher than barite, which means to achieve the same density, less weighting materials can be used. The hardness and abrasivity of iron oxide are higher than barite, which may add additional cost to the drilling process.
