The Role of Slurry Flow Simulation in Oil & Gas and Chemical Industries
In oil & gas and chemical processing industries, slurry transport is a major challenge due to the presence of solid-laden fluids, high-pressure environments, and complex multiphase interactions. Poor slurry flow management can lead to:
- Pipeline blockages and erosion, increasing maintenance costs.
- Pump inefficiencies, leading to increased energy consumption.
- Unstable pressure fluctuations, affecting production and transport processes.
- Regulatory compliance challenges, particularly with environmental laws related to effluent discharge.
With AFT Fathom 13’s 4-Component Slurry Model, companies can precisely model slurry flow behavior, optimize pump performance, and design safer, more reliable transport systems.
Oil & Gas Industry Applications: Optimizing Slurry Transport for Drilling Fluids and Produced Water
Case Study 1: Preventing Blockages in Drilling Mud Circulation (Saudi Arabia)
The Challenge
A leading offshore oil drilling company in Saudi Arabia faced frequent blockages in drilling mud circulation systems. The high-density, multi-particle slurry flow caused inconsistent flow rates, excessive pressure drops, and rapid wear on pipelines and pumps.
Solution Implemented by AFT Fathom 13
- The 4-Component Slurry Model was used to define different particle sizes in the drilling mud (barite, bentonite, and rock cuttings).
- Engineers optimized fluid velocity to prevent settling of heavier particles.
- The company adjusted piping layouts and flow rates, reducing turbulence-induced erosion.
Results
45% reduction in pipeline clogging events, improving drilling efficiency.
Extended pump life by 30%, minimizing maintenance downtime.
More consistent pressure profiles, stabilizing fluid circulation.
Case Study 2: Improving Produced Water Treatment in Oil Refineries
The Challenge
A refinery struggled with solid-laden produced water from oil extraction, causing separator inefficiencies and unexpected equipment failures. Sludge and sand deposits clogged transfer pipes, reducing flow rates and increasing the frequency of equipment cleanouts.
Solution Implemented by AFT Fathom 13
