.... The current challenge is how to develop these reservoirs that have high uncertainty in net pay. In the recent past, several wells were completed in the interbedded sandstone sequences and no flow was reported. As a result, a review of log, core, fluid, well tests, PLT, pressure data, and the method of net...

... but because of layering. In these situations, it is the net pay and reserves, not the necessary the permeability, that is changing. This paper compares the pressure transient behavior of a multi-layer system with that of a composite system, and illustrates the similarities and the differences...
