Abstract
A system and method for fracturing an earth formation surrounding a borehole includes an elongate conduit positioned in the borehole. A packer assembly is provided about the conduit and is adapted to seal an annulus between the conduit and the borehole. A packing passage is provided and adapted to communicate a first side of the packer assembly to the annulus between the conduit and the borehole on a second side of the packer assembly. The conduit has at least one inlet into the conduit on the second side of the packer assembly adapted to allow flow from outside of the conduit to the interior of the conduit. The conduit has at least one ported sub having at least one lateral jet aperture therein adapted to direct fluids within the conduit into the earth formation to fracture the earth formation.
