All software that is designed to interpret production logs usesthe same technique when it comes to dealing with flow acrossa perforation. This technique involves creating “stable” zonesabove and below the designated interval, and the flowcalculations are done at these “stable” zones, and thusimplying that the flow from the interval is equally distributedalong its length.In some cases, it becomes of extreme importance to determinewhich parts of the perforated interval is actually producing,and producing what. This case arises when some perforatingintervals are covering more than one type of rock, or differenttextures of the same formation.In this paper, we will show two methods that will define thelocation and type of flow from every foot of aperforated interval.A real case is introduced in this paper; the production logsinvolved are interpreted in the conventional manner, and alsowith the new techniques. The results show that with the newtechnique, a clear definition of the contribution of each foot ofthe perforated interval is shown, and an accurate assessment ofthe stimulation job performed in the well was achieved.
