Eushaw Dynamic Simulator (EDS)
Comprehensive Production and Wellbore Simulation Software
Overview
Eushaw Dynamic Simulator (EDS) is an advanced multiphase flow and production optimization platform designed to help operators model complex well and reservoir systems with precision. Developed by Ashaw Energy, EDS combines real-time simulation, advanced thermal and fluid modeling, and powerful visualization tools to enhance operational performance from field development to production.
The EDS was first released in 2020, originally developed to support the design of inflow control devices for both thermal and conventional operations. Subsequent versions expanded its capabilities by incorporating features such as artificial lift modeling and hydraulic fracture stimulation. However, the primary focus has remained on integrating the latest scientific advancements into the application while ensuring it remains user-friendly and accessible for engineers.
The EDS enables production optimization throughout the entire field lifecycle—from development to operations—by applying the latest targeted scientific insights to effectively address flow assurance challenges.

SAGD Solutions
Eushaw-Thermal is Parallel-Dynamic software that handles the complex non-linear flow surrounding the producer in SAGD application. Eushaw-Thermal can solve most of the challenges associated with Flow-Control-
MoreSolvent-SAGD Solution
Fully Compositional Modelling
The Eushaw Solvent module includes multiple EoS models: Peng-Robinson and Soave-Redlich-Kwong. The Solvent module also includes the linear solution (Flory-Huggins Theory) and PC-SAFT EoS to model Asphaltene Phase Behavior. Eushaw is a compositional software and calculates the azeotropic point to decide if water or solvent is flashing and uses such flashing technique to capture the near-wellbore and inside FCD.

Shale-Gas Design and Analysis
One of novel capabilities is to design and model hydraulic-fractures in shale gas reservoirs. In Eushaw HF models are developed such: P3D, EP3D, CP3D, ILSA and DDM. These models are highly capable to capture the complexity of stress variation in the reservoir and also track the tip of the fracture that grows into reservoir and leak-off rates. For proppant transport also can be modeled by simple and complex models such as CFD. The HF is coupled with reservoir engine that handles the phase changes such as condensation and gas-liberation.

Prediction and Analysis
Scale and corrosion can be a major cause of tubing failure. Reducing and controlling corrosion is, in many cases, one of the primary ways you’ll be spending your time around an oil and gas lease. It is most often an issue with wells that produce a great deal of water. Eushaw simulator provides a prediction on localized pitting, general corrosion and also the likelihood of corrosion. Eushaw software includes all the recent development such as Papavinasam and Sun-Nesic models.
