What is a Weighting Agent? Definition from Trenchlesspedia

What Does Weighting Agent Mean? A weighting agent is a material that, when added to drilling fluid, increases its density. The most commonly used weighting agents in the drilling industry are barite and hematite, which meet specifications by the American Petroleum Institute (API) and the International Organization for Standardization (ISO).

weighting agent Oilfield Glossary

weighting agent 1. n. [Drilling Fluids] Also known as weighting material, a high- specific gravity and finely divided solid material used to increase density of a drilling fluid. (Dissolved salts that increase fluid density, such as calcium bromide in brines, are not called weighting materials.)

Weighting Agent Planet

CALCIUM CARBONATE is used as a bridging agent and/or weighting material in oil base and water base drilling fluids, work over fluids, and completion fluids. It comes in a wide variety of particle sizes ranging from 325 mesh (35 µ) to 30 mesh (550 µ). Custom sizing for particular applications is also available

Effect of Different Weighting Agents on Drilling Fluids

Weighting agents such as barite, micromax, ilmenite, and hematite are commonly added to drilling fluids to produce high-density fluids that could be used to drill deep oil and gas wells. Increasing the drilling fluid density leads to highly conspicuous fluctuation in the drilling fluid characteristics. In this study, the variation in the drilling fluid’s rheological and filtration
