... a challenge, because wells only intercept a very small volume of rock, and hence have a high chance of under-sampling fracture networks. Among all the fracture properties, fracture length is one of the most difficult aspect to characterize, as the fracture planes are often truncated by wells. In practice...

... requires greater effective fracture length to match production. This is consistent with the operator's experience that outer wells outproduce inner wells within weeks or months from the start of production. We set up two simulation models, a "Hi Perm" model with a 850 nD Point Pleasant system...
