DEVICE AND METHOD FOR OBTAINING, ESPECIALLY IN SITU, A CARBONACEOUS SUBSTANCE FROM AN UNDERGROUND DEPOSIT

摘要

The invention relates to a device and a method for extracting a carbonaceous substance, especially bitumen or extra-heavy oil, from a reservoir (6). Thermal energy can be supplied to the reservoir (6) to reduce the viscosity of the substance. For this purpose, at least one conductor loop (10, 11) is provided as an electric/electromagnetic heater to be inductively supplied with power, a conductor (10) of the conductor loop (10, 11) being surrounded by a liquid-carrying conduit (12) in at least one section and said liquid conduit (12) being perforated so that when liquid is supplied said liquid penetrates into the reservoir (6) from the liquid-carrying conduit (12) via a perforation (21).
