Thermal process is applied in unconventional reservoirs of oil shale and heavy oil (bitumen).
In oil shale reservoirs, in-situ heating process such as electrical heating and hot fluid injection is applied to thermally decompose organic matter called kerogen, involving multiple kinetic reactions. We provide optimized scenarios with high productivity and energy efficiency and minimized environmental impact.
In heavy oil (bitumen) reservoirs, hot fluid of steam or water-solvent mixture is injected to mobilize viscous heavy oil.
In shale gas reservoirs, thermal process can be also applied along with hydraulic fracturing for thermal desorption of gas.
Each process is scientifically complex, and its numerical simulation involves highly non-linear equations to solve. Most advanced numerical methods are applied to solve problems accurately and efficiently.
