... configurations with distinct zones having multiple reservoir layers isolated by packers behind the tubing. The flow events in such cases happen behind the point of measurement and PLT sensors are blind to respond to them. Another technique is introducing tracer materials into injection water to establish...

..., further analysis is required to identify zonal productivity index (PI) and water cut (WC) of each reservoir layer, before engineers can decide and manipulate the FCV flow area configuration of each reservoir flowing in a commingled setting. The current process of allocation using production logging...

... was divided into sections, each one connected to the corresponding reservoir layer. PVT properties and fluid description were input in the two layers. A suitable Shell proprietary multiphase flow correlation was applied for the modelled, highly deviated well. Figure 2. "Segmented" approach used...

... and have lower permeabilities ranging from 50 to 250 millidarcies and porosity ranging from 16% to 22% ( Fig. 3 ). These intervals have a fining- upward lithologic signature, as evidenced from open hole logs of the wells ( Fig. 2 ). The reservoir layers are illustrated in the cross-section shown in Fig. 4...
