PERFORMANCE EVALUATION OF MICROEMULSION ACID FOR INTEGRATED ACID FRACTURING IN MIDDLE EASTERN CARBONATE RESERVOIRS

Performance evaluation of microemulsion acid for integrated acid fracturing in Middle Eastern carbonate reservoirs

Considering the characteristics of carbonate reservoirs in the Middle East, a low-viscosity microemulsion acid that can be prepared on site and has an appropriate retardation ability was developed.It was compared with four conventional acid systems (hydrochloric acid, gelled acid, emulsified acid and surfactant acid) through experiments of rotating
