Oil and gas systems contain water - and the water may cause many problems!
It is therefore important to be able to track water through the process and calculate propterties of the water phase correctly.
Most process simulation tools use Equations Of State (EOS) such as the SRK or the PR EOS, and they are not able to simulate the properties of the water phase correctly. For example, solubility of gases in the water phase is not simulated correctly with most EOS. This can have serious implications for the process design and operation. Also, most process simulators do not include salts/ions, acids/bases and pH is not calculated.
With the MultiScale software, Scale Consult can simulate compositions and properties of the water phases through the process. This includes:
Results from a process simulation using a ordinary process simulation tool (for example HYSYS), can be used to build the same process in MultiProScale and re-simulate the process with an accurate model for the water phase.
Release of H2S at different locations in a process. Simulations are based on production profiles over 17 years.
Example: Low GOR HP field. Process simulations indicated very little gas - just enough for fuel gas. Re-simulating the process with MultiScale, including produced water and gas released from the water, showed that the gas rate increased 100%, but the fuel gas will contain up to 25% CO2 and will not burn.
Scale Consult was foundend in 2012. We are specialists in scale prediciton/management, aqueous chemisry and MEG systems. Since 2012 we have delivered more than 45 projects for about 20 different international clients.
