OLI Systems
The smart choice for ANY application involving electrolytes  


  • Beginning with the concept  

    From the early decisions needed in feasibility studies, through proof-of-concept and trying out different process configurations, OLI’s accurate and in-depth studies in electrolyte chemistry can help drive the right choices when your process involves electrolytes.


  • During detailed design  

    For any water-containing stream in your plant, using OLI to determine phase and ionic composition is the best choice for the accurate and detailed information you need.  OLI is essential for collecting vital information regarding potential trouble spots in your design. Step out of your process and into the expertise of electrolyte thermodynamics to arrive at the best decisions.

  • Through debottlenecking, troubleshooting and optimization   

    OLI is valuable in asking the what-if questions that can make the difference in your operations. Eliminate the guesswork and bring understanding to where trouble is occurring, where corners can be cut, and where special measures may be needed.  Reduce risk and increase confidence in your recommendations.  Electrolyte chemistry is non-intuitive and a wrong answer is worse than no answer at all. 


As wells age, brine production rates increase and with it, mineral scale prediction. Using OLI is a smart choice to assist in water management, from produced water handling to frac water compatibility, optimal mixing rates for injection waters, and compatibility of brines injected into disposal wells.

Applications include accurate characterization of downhole conditions from surface samples, simulation of downhole and surface facilities scaling, acid stimulation, gas lifting, water flood, and gas plant modeling,

A unique solution for simulating water reclamation and water reuse processes

OLI’s water chemistry expertise brings value to the growing field of water re-use, reclamation, and purification. OLI technology includes the key thermodynamic elements needed to design and optimize water treatment operations. Furthermore, as the chemical complexity of your process changes, you can be confident that the quality of software predictions will keep up with your demands. That is because the OLI model can predict accurately, properties of the most challenging “water types and salinities” – from lake water to seawater, brackish well water to salt-saturated oilfield waters, and a variety of industrial effluents. In short, OLI software model complex salt solutions with a range and level of accuracy that simply cannot be achieved elsewhere.



Reduce your expensive laboratory budget to a fraction of what it is now by using OLI as a virtual laboratory that can screen out unlikely or thermodynamically infeasible experiments, and hone in on a more effective and efficient design of experiments. The OLI Studio is a chemistry lab on your laptop that will give you valuable chemistry information to guide and target your lab experiments.

Working with autoclaves? OLI makes calculating autoclave loadings simple and takes the guesswork out of setting targets or finding optimal operating conditions.


When you have potential aqueous corrosion due to chemical attack (the bulk solution chemistry in contact with a metal surface) OLI can provide valuable insights into which is the most aggressive chemical constituent in your service, and how you will be able to mitigate and minimize corrosion.


This information can be used to either alter the chemistry, change the material, or alert you to the need for inhibition. Use OLI software as a soft sensor to calculate a corrosion rate for a given temperature, pressure, composition and flow regime.



Understand your Corrosion Environment



Answer a key design question using OLI:  whether a proposed material of construction will be resistant to attack by your process fluid.  And when there is a problem, OLI can calculate a rate of general corrosion or of a pitting rate, or calculate remaining asset life when pitting is occuring.
