Abstract
Apparatuses and methods for positioning a flexible hose into a wellbore with a protective housing are disclosed. A flexible hose is contained within a protective housing and both are positioned into a wellbore to a desired depth. Pressure can be applied to an interior of the protective housing, and a packoff seals between the flexible hose and the protective housing, causing the pressure to eject the hose from the protective housing.
