Evaluation et interprétation des résultats des acidifications dans le champ de Hassi Messaoud (Puits MDZ663 et MD519)

Abstract

Acidification is a technique for improving the productivity or infectivity of oil and gas wells. In matrix stimulation, acid is injected into the formation to remove damage near the well that reduces well productivity. Objective of this study is the evaluation and interpretation of acidification results in the well MDZ663 and MD519 in the field of Hassi Messaoud Treatment fluids are injected at an injection pressure lower than the limit of fracturing pressure. Operation has succeeded in the MD519 and has echole in the MDZ663 for not respect the procedure
