At present, there is a qualitative change in the structure of proved oil reserves in the direction of increasing the proportion of heavy oils and ultra-heavy oil. World proved reserves of such hydrocarbons significantly exceed the light oil reserves. Russian Federation has significant geological reserves of heavy oil, which average from 6 to 7 billion tons. The great experience in the development of heavy oil reservoirs and application of various EOR technologies was accumulated in the Timan-Pechora province, at two large fields of heavy oil: Permian-Carboniс deposit of Usinskoye field and Yaregskoye oilfield. Factors that negatively affected on development indicators were identified. In this connection, there was a need to improve existing and develop new, more efficient technologies for heavy oil production. For solving these problems, was created the new area of laboratory maintenance for research of heavy oil reservoirs on the base of Core Examination Centre at the Division of PermNIPIneft Branch of LUKOIL Engineering LLC in Perm. The main Centre activity is experimental investigations, which aimed at studying and selecting new technologies for extraction of high-viscous and ultra-viscous heavy oils, including thermochemical technologies, for the fields which developed by LUKOIL company. In 2018-2019, a number of research works are plan in this direction: bed stimulation mixed technologies such as by heat-transfer agent, carbon dioxide and a multifunctional chemical composition based on surfactants.
The article presents the results of previous experimental studies, describes the equipment of the laboratory complex, and its technical characteristics. The stages of the planned studies of combined thermal treatment technology, СО2 and surfactants composition are briefly described.
