Paper Number: SPE-195220-MS
... Abstract Estimating the effective permeability and microfracture (MF) conductivity for unconventional reservoirs can be challenging; however, a new method for estimating using a stochastic approach is discussed. This new analysis method estimates matrix permeability and the unpropped and...

... lacustrine deposits, so the grain sizes tend to be much smaller. This also causes the pore sizes to be smaller and the permeability to be much lower, typically in the microDarcy ( d) and nanoDarcy (nd) range. For example in the Eagle Ford formation, the average matrix permeability tends to be 1 to 1000 nd...

Abstract Managing adequately pressure drawdown should be a key technical reservoir management driver due to its major impact on cash flow, acceleration and final recovery factor for operating hydraulically fracture shale gas condensate producers. Permeability should be regarded as a key dynamic...

This analysis proved that permeability, in most cases, had greater negative impact on well performance than skin when there was a higher permeability layer in the reservoir. It should be noted that this can reverse; skin can be the most significant negative factor...

The horizontal layers might have created flow paths for fluids, but apparently the reservoir has sufficient intrinsic permeability to allow that migration through separate minor horizontal structures. This condition would be similar to the intermediate layering conditions observed in Fig. 2a...
