* Decreasing [[grain size]] decreases permeability.
* Decreasing [[grain size]] decreases permeability.
* Increasing grain sorting increases permeability.
* Increasing [[Core_description#Maturity|grain sorting]] increases permeability.
* Increasing grain rounding increases permeability.
* Increasing grain rounding increases permeability.

| Estimate grain size, sorting, and porosity using the [[depositional environment]]. For example, if a reservoir is a beach sand, it should be fine to medium grained and well sorted with well-rounded quartz grains
