Pipesim
steady-state multiphase flow simulator
Overcome fluid flow challenges and optimize production.
Olga wax
Predict wax buildup and determine thermal insulation, heating, chemical injection, and pigging requirements to mitigate wax buildup.
Overview
The Olga Wax module calculates the deposition and transport of wax components along the pipeline. It models the effects of increases in pipeline roughness, decreases in pipeline diameter, and the increased apparent viscosity of the oil phase with precipitated solid wax particles.
Applications
Pigging for wax removal
Thermal insulation due to wax build-up
Active heating
Chemical injections
Benefits
Wax deposition occurs on the inside surface of a flowline due to molecular diffusion when the pipe wall temperature falls below the wax appearance temperature (WAT). Wax precipitation occurs in the oil bulk flow when the bulk temperature is below WAT.
The Wax module supports tuning fluid properties related to molecular diffusion, dissolution, shear related wax transport, and effective viscosity of an oil/wax mixture to dynamically model wax deposition, dissolution, and transport effects. The Olga simulator also simulates pigging operations for wax layer removal and transport.
Features
- Calculates deposition and transport of wax
- Dynamic prediction of wax deposition using RRR, Heat Analogy, and Matzain diffusion models.
