Abstract
Carbonate reservoir stimulation has been carried out for years using HCl or HCl-based fluids. High HCl concentration should<br>not be used when the well completion has Cr-based alloy in which the protective layer is chrome oxide which is very soluble<br>in HCl. HCl or its based fluids are not recommended either in shallow reservoirs where the fracture pressure is low (face<br>dissolution) or in deep reservoirs where it will cause severe corrosion problems.
