A wellbore assembly for fluid treatment of a well includes: a tubing string including a tubular wall including an outer surface and an inner wall surface defining an inner diameter, an shift gap in the inner wall surface, the shift gap having a diameter greater than the inner diameter, a fluid port extending through the well providing fluid access between the inner diameter and the outer surface, the fluid port positioned in the shift gap, a sliding sleeve valve slidable in the shift gap between a position closing the fluid port and an open position wherein the fluid port is open to fluid flow therethrough between the inner diameter and the outer surface, the sliding sleeve valve in the open position creating a shift gap in the shift gap in which the fluid port is located, the shift gap having an axial length; and a tool for locating the fluid port in the tubing string, the tool including: a body including an upper end, a lower end and an outer surface extending therebetween defining an outer diameter, a locking protrusion encircling a circumference of the body, at least one of the locking protrusion having a length measured along the tool's long axis, the length being selected to fit into the shift gap. |
