Abstract
HEDTA proved to be efficient in dissolving ions like calcium, magnesium, sodium and potassium from sandstone and carbonate rocks whereas GLDA introduced more numbers of large pore holes in case of dolomite acidizing, leading to greater increase in permeability. This research also summarizes the results obtained through a variety of tests which includes dissolution, Inductively Coupled Plasma, Nuclear Magnetic Resonance and mineral analysis, which helped in understanding the interactions of chelating agent with formation rocks.
