Reservoir Simulation (ECLIPSE) — History Matching & Compositional Model (Gas Condensate Simulation)

Reservoir Simulation (ECLIPSE) — History Matching & Compositional Model (Gas Condensate Simulation)

Description:
We need an experienced reservoir simulation engineer proficient in ECLIPSE to complete several tasks involving existing field models and one compositional mechanism model.

Task Details:
1. There are 7 reservoir models, each typically containing 1 production well (some up to 3 wells).
2. The initial models are already built, but they are a few years old and need updating with approximately 3 years of new production and pressure data for history matching.
3. Historical data (pressure, production rate) will be provided later — for now, the main goal is to ensure the model runs properly.
4. Deliver all runnable project files and result plots (pressure, saturation, production curves, etc.).
5. Maintain strict confidentiality.

Additional Model: Gas Condensate Compositional Mechanism Model
• Build a compositional model to simulate gas–condensate behavior and gas dissolution in water.
• Geometry: 2 m × 2 m rectangular grid, around 100 cells.
• The water component should contain dissolved gas (C1);
the gas phase should include a water component to simulate condensate formation.
• Initial water saturation = 20% in the gas zone to simulate bound water.
• Base component set on the provided actual model.

⸻

Timeline:
• Oct 30 – Nov 3: Build compositional model & make existing field models runnable.
• Nov 3 – Nov 9: Finish first 2 models (history matching).
• Nov 10 – Nov 16: Finish next 2 models.
• Nov 17 – Nov 23: Finish another 2 models.
• Nov 24 – Nov 28: Final model completed.
