Abstract
A ported sub treatment system in which well treatment materials are pumped into an uncased portion of a well through a jointed tubing string having a number of holes at specific locations along its length such that these materials are able to be distributed as desired by the operator, through these holes, along the length of the well. The treatment system is also able to provide sufficient pressure such that treatment materials are able to penetrate or fracture the rock surrounding the well, if necessary.
