Wax Deposition & Pour Point

Estimate WAT, pour point, deposition rate, and pigging frequency from crude oil properties.

Crude Oil & Pipeline Properties

API Gravity

Wax Content (wt%)

Operating Temp (F)

Ambient / Seabed Temp (F)

Pipeline ID (in)

in (before pigging)

Engineering formulas

WAT estimation: WAT ~ 30 + 2.5 * WaxContent(%) + 0.3 * (50 - API) [simplified correlation]

Pour point: PP ~ WAT - 20F (typical offset)

Deposition rate: Based on (WAT - Tamb) driving force, wax content, and flow regime. Simplified: rate ~ 0.01 * Wax% * (WAT - Tamb) / 100 in/month

Pigging interval: Pig when wax thickness reaches ~5% of pipe ID. Interval = (0.05 * ID) / deposition_rate * 30 days
