... starting the procedure. The method homogenizes permeability in one particular direction while assuming no communication or perfect communication in the other directions. The procedure then is repeated for all directions. The harmonic and arithmetic averaging equations for steady- state radial flow...

.... This quantification had to honor the various fluid contacts, the fluid gradients, and log observations, such as water up to, gas down to, and geochemical core analysis. We evaluated the degree of communication between drilled fault Segments by determining probabilities of static-pressure communication between...

...David M. Braisted; Richard M. Spengler; Ralph A. Youie Summary Pulse testing was used in the Fortescue field to clarify reservoir geometries and fluid communication pathways. The high communication levels demonstrated in the test data required a nonstandard analysis of the pressure responses...

... evidence of a preferred flow direction toward the southwest. In addition, they confirm the existence of communication across the shoal margin between foreslope and back reef facies and provide insight into the different flow characteristics inherent to the back reef and shoal margin. Excellent results were...

... form permeable zones parallel to bedding planes that extend laterally for large distances. The most highly fractured zones correspond to areas with the greatest rate of change in structured dip. Initially, it was not known whether the Ekofisk and Tor formations were in communication...

The upper layer comprises h 1 , k 1 , and ϕ 1 ; the lower layer is h 2 , k 2 , and ϕ 2 ·The parameter b is used to represent the fraction of the lower layer that is in vertical communication with the upper layer and to measure the degree of crossflow.

... of production—constant wellbore pressure and constant rate—are considered. In the first part, the fractures are assumed to communicate only at the wellbore. The results given in this section are intended to provide engineers with analytical capabilities to examine responses in wells where the layers that have...

... that planning for an improved recovery program should begin as soon as possible. Knowledge regarding the degree of communication in the reservoir, the magnitude of any directional permeability trend, and the interwell reservoir properties would be needed to select a suitable reservoir management method.
