Abstract
Petrography and Porosity of the Cow Run Sand, St. Marys, West Virginia
John C. Griffiths
ABSTRACT
The petrographic characteristics of some Cow Run sandstones from four wells at St. Marys, West Virginia, are described and the relationship between petrography and porosity (and logarithm of the permeability) are evaluated by multiple regression approach.
It is shown that carbonate cement, when it exceeds 5 percent by weight, controls the porosity. When less than 5 percent of carbonate occurs the grain size, size-sorting, quartz, and silica cement are the main factors controlling the porosity in these oil sands.
