System For Cyclic Injection and Production From a Well
First Claim
1. A system for injecting an injection fluid into a wellbore formed in the earth formation and for producing hydrocarbon fluid from the earth formation via the wellbore, the system comprising an injection conduit extending into the wellbore and being in fluid communication with a plurality of outlet ports for injection fluid, the system further comprising a production conduit extending into the wellbore and being in fluid communication with at least one inlet section for hydrocarbon fluid, wherein the injection conduit is arranged to prevent fluid communication between the injection conduit and each said inlet section, wherein the injection fluid is a heated fluid which is injected into the formation in order to reduce the viscosity of hydrocarbon fluids within the formation;
- said outlet ports are comprised in a plurality of series of outlet ports;
the system comprises a plurality of said inlet sections; and
said inlet sections and said series of outlet ports are arranged in alternating order in longitudinal direction of the wellbore.
