MSE uses VMG Sim and VMG Thermo for developing process designs of oil and gas production facilities. However, where specified by a client, MSE also uses alternative simulation packages such as HYSYS, PIPEPHASE and others.

A key deliverable of the process simulators is the compositional analysis of the field test data gathered from wells' samples, separator outlets, at various stages of a compression process. The compositional data is analysed using a variety of Equations of State (EOS) available in the thermodynamic packages. The normal simulations are performed with Peng Robinson or SRK. Lee Kessler and Lee Kessler Plocker are used for gas mixtures containing high concentrations of CO2 and H2S gases.
 

MSE also uses BWRS equation of state which are used extensively by the compressor manufacturers for compressor selection and performance prediction. BWRS is used for light hydrocarbon gases and provides more accurate results at very high pressures as is required for gas injection and other applications.

The process simulations provide dew point, bubble point curves of gas mixtures as well as hydrate formation lines, critical for testing and preventing hydrate formation strategies. In addition, all processing unit operations can be modelled including heat exchangers, separators, expanders, turbine and pumps etc. This data is used for refrigeration and dew point control of gases and gas mixtures.



MSE also analyses the process equipment as currently installed and assesses its suitability for new operating conditions. It analyses all the commonly used oil and gas equipment such as heat exchangers, separators, air-coolers and refrigeration equipment. This enables MSE to examine the entire processing facility when working on the re-design of compressors.
