Abstract
A system for recovering hydrocarbons comprises a downhole steam generator for coupling with a packer in an injector well, an umbilical device coupled to the downhole steam generator for lifting or lowering the downhole steam generator in the injector well, a first shear point disposed between the downhole steam generator and the packer, and a second shear point disposed between the umbilical device and the downhole steam generator, wherein the first shear point has a shear strength that is different than a shear strength of the second shear point.
