... additives [i.e., potassium chloride (KCl) with/without hydrochloric acid (HCl), commercial clay stabilizers, liquid CO 2 , and isopropyl alcohol] were assessed as permeability remedies. The results showed that injection brine caused greater permeability damage than produced brine. KCl solutions preserved...

... experiments are reported in this paper. Measurements are made from room temperature to 85 ?C at rotational speeds of 100 to 1000 rpm and acid concentrations of 0.05 to 5N HCl (0.2 to 17 wt%). The results show how acid dissolution rates change as the reservoir rock varied from 3 to 100 wt% dolomite. Factors...

... reservoir temperature is 275 °F and initial reservoir pressure is 7,000 psi. Because of the high bottomhole temperature and the corrosive nature of HCl, especially at high temperatures, a special acid system was needed to effectively stimulate the carbonate reservoir. Reaction rate of HCl/formic acid system...
