The document discusses MAST v. 2.4, a multiphase flow analysis and simulation software. It describes MAST's structure and capabilities for modeling multiphase flow transition, injection, and production. Graphs show good agreement between MAST's calculated results and experimental data for pressure drop and liquid holdup. The document also lists client projects from 2009 to 2016 where MAST was used for multiphase flow analysis, including slugging studies, pump and pipeline performance, and operational envelope analysis.
