Abstract
An apparatus is provided for delivering a substance containing hydrocarbons from a reservoir. The reservoir can be subjected to thermal energy in order to reduce the viscosity of the substance. The apparatus includes at least one conductor loop for inductively applying current for electric/electromagnetic heating of the reservoir, and a pressurization device for injecting a liquid into the reservoir in liquid form. A preparation entity extracts the liquid that is to be injected from a reservoir liquid that is taken from the reservoir or from a medium that is taken from the reservoir.
Claims17
An apparatus for extracting a substance containing hydrocarbons from a reservoir, wherein the reservoir can be subjected to thermal energy in order to reduce the viscosity of the substance, the apparatus comprising:
- at least one closed conductor loop partially extending horizontally in the reservoir for inductively applying current, the at least one closed conductor loop being provided an electric/electromagnetic heater of the reservoir;
- a pressurization device for injecting a liquid into the reservoir in liquid form,
- wherein a processing entity extracts the liquid that is to be injected from a reservoir liquid that is taken from the reservoir or from a medium that is taken from the reservoir;
- and
- wherein a conductor of the conductor loop is surrounded in at least one section by a liquid carrying conduit for injecting the liquid into the reservoir.
A method for extracting a substance containing hydrocarbons from a reservoir, wherein the reservoir is subjected to thermal energy in order to reduce the viscosity of the substance, for which purpose at least one conductor loop for inductively applying current is provided as an electric/electromagnetic heating facility, the method comprising:
- taking a reservoir liquid or a liquid in a medium from the reservoir,
- extracting a liquid from the reservoir liquid or the liquid in the medium via a processing entity,
- increasing the pressure of the liquid from the reservoir liquid or the liquid in the medium using a pressurization device, for injecting the processed liquid from the reservoir liquid or the processed liquid in the medium into the reservoir in liquid form, injecting the liquid from the reservoir liquid or the liquid in the medium into the reservoir,
- transporting the liquid from the reservoir liquid or the liquid in the medium into the reservoir via a liquid carrying conduit, and introducing the liquid from the reservoir liquid or the liquid in the medium into the reservoir via a perforation or slots in the liquid carrying conduit, wherein the liquid carrying conduit surrounds at least a section of a conductor of the conductor loop.
