A deep well flexible hose for use in extracting fluids and gases from deep wells includes a relatively flexible hose portion being of a length sufficient to extend to an operable position within the well, wherein the hose portion is of a predetermined temperature and pressure limit, corrosion resistance and weight load capacity and elasticity factor such that when the hose portion is so disposed in the well to the operable position, the hose portion's elasticity factor is exceeded due to the weight load normally exerted and means fixably connect to the hose portion for preventing the hose portion's elasticity factor from being exceeded at the operable position due to the weight load. A method is also provided.
