Advanced Thermal Reservoir Simulation

Applications

Thermal recovery methods are typically used in heavy oil reservoirs where the high oil viscosity can be sensibly reduced with temperature increases. Advanced thermal reservoir simulation can be applied to the following areas:
• Single well huff and puff
• Continuous steam injection
• Hot fluid or gas injection
• CO2 gas or natural gas injection
• Well bore heaters and simple combustion
• Steam assisted gravity drainage (SAGD)
• History matching

Technical Features

• Combined Serial and Parallel Thermal Reservoir Simulation
• Irregular Domain Decomposition
• High Parallel Computation Efficiency
• Cost Effective Computation
• Flexible Pre- and Post- Processing

Model of enhanced oil recovery

Methodology

Step 1: Select parameters and their ranges

Step 2: Run simulator and record effects on oil recovery

Steps 3 & 4: Organize simulator outcomes and map a response surface to variations in the input parameters

Step 5: Using the mapped results as an analogue to the simulator, apply Monte Carlo techniques to determine the uncertainty (probability distribution) in oil recovery associated with each parameter
