Le rôle des méthodes de l’acidification pour évaluer la production dans le champ Haoud Berkaoui (2009/2010

Abstract

Several types of damage are found in the wells. These guys are connected either to the production itself or to response operations on wells (drilling operation, Work over, completion, and stimulation). 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 reduce well productivity. Treatment fluids are injected at an injection pressure lower than the limit of fracturing pressure. The application of the matrix acidification in most studied wells (BKRE1, OKN68) in the field of HBK gave good result which is materialized by the net increase production throughput.
