Secondary  and Tertiary recovery processes  can lead  to severe and permanent reductions in permeability due to the interactions  between injected fluied  and the reservoir  rock  that is especially true in high clay content , low  permeability,  poorly consolidated reservoirs.After  the fluid  with  a high  PH  value enters  the reservoir,the  texture of clay minerals and siliceous cement  in the reservoir is destroyed due to the dissolution  of clay minerals and cement and  the release  of fine particles produced ,thus  causing reservoir plugging. Formation  damage  could  be bith  temporarily  due to the precipitation  of reaction products caused by interaction between high PH  fluids and reservoir rock  which  will result  in pore plugging .In this study ,aseries of core  flooding  experiments have been carried  out  to determine  the critical PH of Alkaline fluids for plug samples of  Fahlyian carbonate formation. Alkaline  fluids with  different  PH (7,8.5, 10 and 12) were injected into plug samples and the alkaline  sensivity  of the carbonate  formation  has been measured in both qualitative and quantitative forms by a new applicable method .Using  this approach  will result  in the accurate estimation of the degree of  formation  damage .result indicate that  used plugs show different  behavior  when exposed  to fluids  with different  alkalinity  and  the degree of  resulted  formation  damage  varies from Zero  to serious  and in certain cases are noticeable and  irreversible. Therefore, PH  of injecting  fluids  must  be kept less than its threshold  value  to prevent  formation damage.
