Abstract:
A chemical injection system includes a TRSV; a communication nipple in operable communication with the TRSV and positioned relative to the TRSV to be downhole of a flapper closure mechanism thereof when installed in a wellbore; a chemical injection line in fluid communication with the communication nipple; and a capillary sleeve receivable at the communication nipple and configured to sealingly convey fluid from the communication nipple to a remote location without affecting operation of the TRSV and method.
