OLGA 2023.1 (one pc)

The OLGA* dynamic multiphase flow simulator models time-dependent behaviors. Dynamic The OLGA* dynamic multiphase flow simulator models time-dependent behaviors. Dynamic simulation is extensively used in both offshore and onshore field developments. From wellbore dynamics – for any well completion – to pipeline operations – for process systems containing any type of equipment – the OLGA simulator provides an accurate prediction of key operational conditions involving transient flow. Together with the PIPESIM* steady-state multiphase flow simulator, Schlumberger provides a complete software solution for design and optimization of production systems.

These notes accompany the release of OLGA 2020.1 from Schlumberger. The notes describe These notes accompany the release of OLGA 2020.1 from Schlumberger. The notes describe changes in OLGA 2020.1 relative to OLGA 2019.1. This document should be read by all users of the program.
