Pond deposits examined as a stratigraphic control on migration and compartmentalization in eolian reservoirs

Katy Ann Duncan, University of Texas at El Paso

Abstract

This is a combined surface and subsurface study that will aid with understanding about how interdune pond deposits can control migration of liquids, including petroleum, through eolian strata. Many productive petroleum reservoirs are located in wind blown or eolian sandstones. The Permian Cedar Mesa Sandstone, Canyonlands of Utah, and the Pennsylvanian-Permian Weber Sandstone, Rangely producing field of northwest Colorado, both contain hydrocarbon reservoirs developed in eolian sandstones. ^ A detailed outcrop and petrographic study was performed in the Cedar Mesa Sandstone and is the focus of paper one in this thesis. At the outcrop of the Cedar Mesa 22 pond deposits were surveyed relative to surrounding eolian deposits. ^ To compare outcrop findings to the sub-surface in paper two, well logs were used to identify 17 pond deposits within the Weber Sandstone. The tops of dunes within the Weber 3 and 5 intervals determined that pond deposits are associated with interdune areas. ^
