Zusammenfassung:	Apparatuses and methods to inject chemical stimulants (284) to a production zone (102, 202) through a string of production tubing (110, 210) around a downhole obstruction are disclosed. The apparatuses and methods include deploying an anchor seal assembly (200) to a landing profile (120, 220) located within a string of production tubing (110, 210). The anchor seal assembly (200) is in communication with a surface station through an injection conduit (260, 264) and includes a bypass pathway (262) to inject various fluids to a zone below. Aparatos y metodos para inyectar estimulantes quimicos a una zona de produccion a traves de un cordon de tuberia de produccion alrededor de una obstruccion dentro de pozo se divulgan. Los aparatos y metodos incluyen desplegar un conjunto de sello de ancla para un perfil de aterrizaje localizado dentro de un cordon de tuberia de produccion. El conjunto de sello de ancla esta en comunicacion con una estacion de superficie a traves de un conducto de inyeccion e incluye una trayectoria de derivacion para inyectar varios fluidos a una zona debajo.
