The estimated effective porosity varies between 5 to 10 percent and average minimum water saturation is about 10 percent. The La Luna Formation has very low permeability...

... for predicting the sonic velocities and dynamic rock mechanical properties were porosity, clay content and bulk density which were taken from the log data. The models for obtaining the static rock mechanical properties were tested against the results of Mini-Frac tests in two offset wells in the Cruse...

In addition, the gas production rate increases with the increased permeability, seam thickness and Langmuir pressure constant while it decreases with the increased porosity and Langmuir volume constant. The numerical...

... is not directly related to clay content but to micro-porosity, that creates a "low contrast resistivity" pay (LCP) effect. Furthermore, when micro-pores are present, they exert a gradually increasing influence as Sw decreases. Their effect is to decrease the saturation exponent "n" and this reduction is related...
