RETINA Simulation™

RETINA Simulation™ is the main and the most technological product of ESTD. It is developed during 4 years using the valuable numerical analysis and software development knowledge of developer team. RETINA Simulation™ is a block oil and compositional, finite volume, unstructured based and parallel reservoir simulator that is built and optimized to be fast and stable specially, for large, complex and fractured heterogeneous reservoirs. It has been tested by numerous real carbonates fractured and non-fractured oilfields in Middle East area. Various companies officially certify its accuracy and stability. The powerful and stable linear solver and preconditioner CPR-AMG based ILU0, fully integrated pre and post processors, and equipped with real time result visualization (plot and grid) and live update of the model are main features of RETINA Simulation.

Based on the characteristics of reservoirs of Iran, RETINA has been fully developed and customized by ESTD experts as the in-house simulator for PEDC to address what ECLIPSE 100 lacks in reservoir studies. It is a three-phase, fully implicit, finite volume, unstructured based and three – dimensional parallel reservoir simulator. A robust solver was implemented to achieve acceptable results of high efficiency for a variety of small homogenous to large heterogeneous/fractured models. RETINA benefits from the Schlumberger Ocean framework to be plugged in Petrel. Thanks to RETINA Petrel Plug-in experts could use RETINA as the engine and the petrel to visualize the results simultaneously. The price of the ECLIPSE 100 license compared to that of RETINA is exorbitant. By developing RETINA, ESTD provides an opportunity for the companies to get their technical knowledge and experiences implemented in a user-friendly software.
