Buoyancy factor

The Buoyancy Factor calculator computes the loss of weight due to immersion in drilling fluid.

INSTRUCTIONS: Choose units and enter the following:

• (MW) Mud Weight

Buoyancy Factor (BF):  The calculator returns a unitless factor.

The Math / Science

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.

Pumping Calculators

• Volume Pumped over time by Pump Flow-rate
• Time to Pump Deadweight Tonnage: Computes time to pump an amount of oil measured by DWT at a pumping rate.   It also returns the volume pumped in barrels.
• Time to Pump Volume by Flow-rate: Computes the time to pump an amount of fluid (e.g., oil) based on a volume and pump rate.
• Duplex Pump Output: Barrels per stroke from a duplex pump.
• Triplex Pump Output: Barrels per stroke from a triplex pump.
• Quintuplex Pump Output: Barrels per stroke from a quintuplex pump.
• Barrel Production: Computes the total volume (barrels) produced over a period of time based on the production rate and duration.
• Annular Velocity: Compute the fluid flow velocity, based on the flow rate and pipe dimensions.
• Mud Buoyancy: Computes the buoyancy in mud
• Volume of a Pipe: Computes the volume of a pipe.
• Weight of Pipe Contents: Computes the weight (mass) based on density and pipe dimensions.
• Density of Oil:
  • Crude at (48° API): 790.0 kg/m³
  • Crude at (40° API): 825.0 kg/m³
  • Crude at (35.6° API): 847.0 kg/m³
  • Crude at (32.6° API): 862.0 kg/m³
• Energy in Crude Oil: 5800000.0 BTU/bbl
• Pump Efficiency
