A downhole tool having a diverter component for directing fluids in different directions within a wellbore. The diverter component has an outer pipe which forms part of the downhole string. The pipe has a through channel and holes through the wall of the pipe. Within the pipe is a sleeve which can be moved. In one position, the sleeve blocks the wall holes and allows fluid to pass through the channel of the pipe. The diverter component may be used in conjunction with packers to seal off sections of the wellbore. The diverter and packer assembly could be used to introduce acid into particular portions of the wellbore.
