Drilling Fluid Additives
Weighting agents
Our high specific gravity weighting agents meet varying density requirements and can be used alone in high pressure situations or in combination with barite to reduce the total solids content. We supply both low and ultra-low abrasive weighting agents for customers to reduce equipment wear and tear.
Densfil®
High purity natural hematite; >4.9 SG
Densfil UF
Ultrafine hematite; >4.9 SG
Densmax™
Manganese tetroxide; micro fine particles, high density and acid soluble; >4.8 SG
Mixed metal oxides
Our suite of mixed metal oxides (MMOs) can be added to a clay containing water-based fluid to enhance its rheological properties. This combination produces a unique thixotropic, shear-thinning fluid that is highly viscous at low shear rates but becomes very thin at high shear rates. These products retain well-bore integrity, especially in high salt-containing and unconsolidated formations, reduce mud loss and prevent loss circulation in highly porous or fractured formations.
