Terminal & Ops Tools
BS&W Net Volume Calculator
Calculate a sediment-and-water deduction from gross volume, with a worked example and an explanation of what the result does and does not include.
API Gravity Blend Calculator
Estimate the API gravity of two streams by blending specific gravity with volume fractions. Includes a worked example and model limitations.
Pipeline Volume Calculator (Line Fill)
Calculate pipe line fill from inside diameter and length. See the cylinder formula, a worked example, and the limits of this planning estimate.
Railcar Fill Limits
Compute the common 93% planning aim and 95% planning ceiling for a tank car from its shell capacity.
Temperature Correction (VCF)
Estimate the volume correction factor that adjusts an observed crude volume to 60 °F.
Liquid Volume Unit Converter
Convert between the three common liquid volume units used in crude oil measurement.
Field Trade Calculators
Pick a trade — each opens its own set of calculators.
All results are an engineering estimate — not for custody transfer. Field measurement and certified tables govern.
