Prevention of hematite settling using synthetic layered ...

2020-6-11  Hematite (Fe2O3) is used as a weighting material to increase the density of the drilling fluid. Hematite has a higher density (5.05 g/cm3) compared with barite (4.2 g/cm3). Because of the high specific gravity and particle size, hematite can separate and settle down at higher temperatures (> 250 °F). The objective of this paper is to assess the usage of laponite

Hematite - an overview ScienceDirect Topics

Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains.

2021-5-18  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.
