Abstract:
1. A wellbore injection system, comprising: 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 in fluid communication with a second fluid flow path that is positioned below the capillary fluid flow path in the wellbore; an injector attached to a distal end of the capillary fluid flow path, the injector comprising an injector flow path, wherein the injector is 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; and an isolation mechanism adapted to isolate the capillary fluid flow path from the wellbore pressure when the injector is not attached to the receptacle.
