Thermal recovery methods within catalytic aquathermolysis is a new promising exploitation approach in extracting heavy oil and natural bitumen. In this technology, the catalyst is added in a stage of injecting high-temperature steam. At the pay zone, three types of reactions takes place: thermolysis, reaction of high temperature steam and catalysis. As a result, the injected steam changes to water transferring its heat to rocks across the interface. Thus, the interfaces of catalyst solutions and hot rocks are cruc...
