Prevention of Barite Sag in Oil-Based Drilling Fluids

High-density weighting materials are introduced to the drilling fluid formulation to provide the required fluid density, such as barite, hematite, manganese tetraoxide, and ilmenite [8,9,10,11,12].Because of its high specific gravity (4.2–4.4), low production cost, and low environmental impact, barite is a common weighting agent [13,14,15].

Development of a New Reservoir-Friendly Drilling

Previous studies and lab experiments show that manganese tetroxide (Mn 3 O 4) is a better weighting agent and represents an excellent alternative to barite and potassium formate. Manganese tetroxide retains relatively high specific gravity and small particle size, which reduces particle settling and sagging in high mud weight formulations.
