Thermodynamic modeling of wax precipitation in waxy condensate oil systems and its field application [PDF]

AIP Advances
During the development and production of condensate gas reservoirs, temperature, pressure, and other operating conditions change as oil and gas are continuously lifted to the surface. Under these conditions, solid-phase substances such as wax, resin, and

Viscoelastic Properties of Waxy Crude Oil

, 2007
Waxy crude oil usually represents viscoelastic property when temperature is below its wax appearance temperature (WAT). The more the waxy crystals precipitated in crude oil, the stronger the structure and the viscoclasticity formed by waxy crystals.
