Abstract:

The present disclosure is directed to a wellbore injection system. The wellbore injection system comprises a capillary fluid flow path positioned in a subsurface wellbore so as to allow fluid communication through the wellbore, the wellbore having a wellbore pressure. A receptacle is in fluid communication with a second fluid flow path that is positioned below the capillary fluid flow path in the wellbore. An injector is attached to a distal end of the capillary fluid flow path, the injector comprising an injector flow path. The injector is capable of being removably attached to the receptacle to provide fluid communication between the capillary fluid flow path and the second fluid flow path through the injector flow path. An isolation mechanism is capable of isolating the capillary fluid flow path from the wellbore pressure when the injector is not attached to the receptacle.
