API barite was easy to settle down, and under a certain pressure difference, mud cake could be quickly formed which decreased the filtration volume (Fig. 8). API barite/WBDFs showed a bimodal distribution (Fig. 10 and Table 4) which contributed to the less filtration loss. The particle size distribution of mMB/WBDFs showed a unimodal peak.
