... are considered to assess the impact of different fluid flow and thermodynamic wax models on wax deposition and pigging operation. 1 INTRODUCTION The phenomenon of wax precipitation and deposition occurs when transporting waxy crude oils via subsea pipelines or in a cold environment onshore. The presence...

... ABSTRACT Asphaltene precipitation and deposition is a major flow assurance challenge, which manifests itself in reservoir, production tubing, and flowline and process facility. Asphaltene may unstable and precipitate due to two main factors, namely high asphaltene content, and high difference...
