Buoyancy Factor Calcualtion
The buoyancy factor for a 13.0 ppg fluid: BF = (65.5 – 13.0) ÷ 65.5. BF = 0.8015. Buoyed weight of drill string = String weight in the air × Buoyancy Factor. The buoyed weight of drill string in 13.0 ppg mud = 350 x 0.8015 = 280.5 Klb. Download Excel Spreadsheet for Buoyancy Factor Calculation both Oilfield and Metric Unit.
Buoyancy pressure
Figure 1 is a pressure-depth plot through an oil column trapped beneath a top seal. The buoyant pressure of the oil column at any depth is the difference in pressure between the oil gradient and the water gradient. The maximum buoyant pressure (P max) is at the crest of the oil column. The buoyant pressure is zero at the free water level (FWL).
