Evaluation of Acidizing Performance Using Well Testing Analysis in Asmari Reservoir of Marun Oil Filed

one of the best method of well stimulation and flow improvement is acidizing. It will reduce skin and damage effects. Acidizing also increases rock permeability and rate of production. But in order to evaluate a a acidizing job some factors such as producctivity index , skin , pressure drop around the well bore and flow rate should be compared before and after stimulation job. this paper aims to evaluate the performance of acidizing jobs in 9 wells of asmari formation of marun oil field. using pansystem software enabled us to compare and analyse the effect of acidizing an improving well performance. more over data related to bottom hole drop flowing pressure a well rate and productivity index of each well before and after acidizing were compared.
