Abstract

A chemical injection system directed at lower completions. The system includes a tubular stinger that is anchored within a upper region of a well but traverses into the lower completion. Thus, a platform is provided for a chemical injection line running from surface to the lower completion. As a result, chemical injection may be directed right at a sand screen and other scale prone features of lower completions.
