摘要：
The present invention relates to a process for the
in situ extraction of bitumen or ultraheavy oil from oil sand deposits (100) as reservoir (1). The reservoir (1) is inductively heated by means of at least one electrical current‑passing conductor (3) in order to achieve a reduction in the viscosity of the bitumen or ultraheavy oil. At least one perforated fluid guide (30), which surrounds or encloses the at least one conductor (3) at least in certain portions, is used to introduce a fluid (45) into the reservoir (1) via the perforation in the fluid guide (30). The fluid (45) reduces an electrical conductivity in the reservoir (1), at least in the surroundings of the fluid guide (30).
