Abstract
A sleeved hose assembly for lateral jet drilling through an ultra-short radius curve. The sleeved hose assembly includes a wire-wound high-pressure hose inserted inside a reinforcing sleeve. In general, wire-wound high-pressure hoses exhibit transverse moduli that are insufficient to resist buckling forces encountered during lateral drilling. A sleeve is selected to encompass a wire-wound high-pressure hose and to exhibit a transverse stiffness sufficient to prevent the combination of the wire-wound high-pressure hose and the sleeve (i.e., a 'sleeved hose assembly') from buckling during lateral drilling. Also disclosed are a method for drilling a lateral borehole using such a sleeved hose assembly, and a method for drilling an ultra-short radius curve using such a sleeved hose assembly. In a particularly preferred exemplary embodiment, the sleeve includes a fiber reinforced epoxy composite having a transverse modulus of about 10 GPa.
