Matrix acidizing tester Reservoir stimulation Matrix acidizing Instruments

The Matrix acidizing tester Reservoir stimulation Matrix acidizing Instruments evaluates the effectiveness of acid treatments in dissolving the mineral matrix of reservoir rocks under reservoir-representative conditions. The treatment effectiveness can be quantified by comparing permeability measurements before and after acid injection. Parameters measured during testing enable graphical representation of acid response in terms of pressure gradient variation and permeability versus time or cumulative acid injection volume.

The system also allows evaluation of the efficiencies of different acid formulations, such as hydrochloric acid and hydrofluoric acid, as well as the effects of variables including flow rate and temperature on permeability enhancement.
