Advanced reservoir simulation plug-in for Petrel®

Optimize your Petrel workflow and make all your simulation runs count using Olyx!

Olyx enables true integrated reservoir simulation studies through advanced history matching and optimization work directly within Petrel’s workflow manager. No more need for third party software to perform advanced history matching.  Olyx allows your Petrel users to carry out integrated uncertainty assessments, advanced history matching studies for more reliable predictions, optimize field development plans and solve complex reservoir optimization challenges. 

Olyx supports production and RFT data and 3D/4D seismic enabling oil companies to completely close the loop between geological modeling and reservoir engineering. It empowers workflows that allow engineers to manage multiple geological realizations and to cooperate with geoscientists. The plug-in is available on Schlumberger’s Ocean Store 



Olyx is shipped with powerful stochastic optimizers, an intuitive objective function definition and a suite of post analysis tools tailored for reservoir engineering. In a multidisciplinary world Olyx works as an optimizer between the static and the dynamic model to ensure more confidence is given to the predictive model. Olyx completes Petrel and this makes it the reservoir optimization tool for the future.

Solve your history matching challenges

Olyx makes it easy for the engineer to identify wells that do not match historic data. Through an advanced objective function definition it’s easy for the engineer to history match on any parameter such as rates, ratios, pressures, cumulatives and 3D/4D seismic.

Match the dynamic behavior

Olyx enables the engineer to incorporate 3D/4D seismic data (Acoustic Impedance, P-impedance, S-Impedance and saturations) as part of the history matching process. This makes it easier for the engineer to understand why particular wells produce too much or too little of the different phases.

Track, map and match on remaining oil

Olyx sets a new standard with the use of seismic observed data for reservoir simulation purposes. Olyx helps the engineer detecting undrained areas, vertical flow barriers, and fault communication and to monitor injection patterns.


Fast optimization

Olyx includes several evolutionary algorithms to facilitate the optimization process. The optimizers have advanced settings and can easily be customized for different optimization tasks.
