The sandstone reservoir rocks of United States oil and gas fields have been studied by the Sandstone Reservoir Committee in order to learn which kinds of sandstones are most commonly productive and which are most prolific. Information has been gathered concerning the areal extent of sandstones producing in combination and structural trap fields, and concerning genesis of those sandstones constituting stratigraphic traps.

Each of the twenty committee members has been responsible for the assembling of data on an area with which he is familiar. For practical reasons, only large fields (5 million barrels or more gross ultimate production) were considered. This analysis of existing fields should help guide the search for additional production from sandstones.
