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 crucial to stimulate the thermal recovery methods. The force and free energy in interfaces of hot catalyst solution and rocks play important roles to mobilize and extract heavy oil and natural bitumen. However, in literature there are no data on catalyst solution and rock interfaces under reservoir conditions. Industrial technology provides a compatible condition to measure the contact angle and interfacial tension at different temperatures and pressures.
This paper discusses the results of contact angles and interfacial tensions of catalyst solution based on Co metal with Silica plate imitating sandstone rocks. Evaluation covers a temperature range from normal to 60C for 290 psi. The pressure dependence of contact angle and interfacial forces are also considered. The experiments are run in Drop Shape Analyzer (DSA 100 by KRUSS) with sessile and pendant drop approaches. |
