Production optimization requires a thorough understanding of reservoir inflow performance and wellbore transport. Scotia's engineers have extensive experience in pressure transient analysis and well performance modeling using Nodal analysis. The combination of these two analytical methods along with a strong theoretical knowledge of the physical principles involved, has allowed Scotia engineers to successfully design and analyze tests of wells all over the world. In addition to in-house software, Scotia utilizes the programs Saphir and WEM under commercial licenses.
