Buoyancy is the reactive upward force exerted by a fluid when an object is immersed into it. **Buoyancy Factor** (BF) is the factor that is used to compensate loss of weight due to immersion in drilling fluid. In drilling the Buoyancy factor is calculated by subtracting the mud-weight from the given constant divided by the constant.

Buoyancy makes objects lighter in a fluid. For example, when swimming or immersed in water one tends to feel lighter than they actually are when out of water.

**EXAMPLE**: BF Using Mud weight in ppg

Given that 65.5 ppg is the density of steel, determine the buoyancy factor for a 17.5 ppg fluid.

BF = (65.5 – 13.0) ÷ 65.5

BF = 0.733
