MAT 700-Matrix acidizing tester


The MAT 700 evaluates the effectiveness of an acid treatment in dissolving the mineral matrix of a reservoir rock, at reservoir-representative conditions. The effectiveness can be quantified by the difference in permeability before and after acid injection. The parameters measured during testing enable a graphical representation of the acid response in terms of pressure gradient variation/permeability versus time/cumulative acid injection volume. The efficiencies of different acids, e.g. hydrochloric, hydrofluoric… as well as other variables such as flow rate and temperature on permeability can also be studied.
