Thermal recovery methods are typically used in heavy oil reservoirs where the high oil viscosity can be sensibly reduced with temperature increases. NUMSIP is a 3-D, three phase, multiple components thermal reservoir simulator. It can be applied to study the following problems:

• Single well huff and puff
• Continuous steam injection
• Hot fluid or gas injection
• CO2 or natural gas injection
• Well bore heaters and simple combustion
• Steam assisted gravity drainage (SAGD)
