Geological and production characteristics of strandplain/barrier island reservoirs in the United States

Abstract

CHAPTER2 DESCRIPTION OF THE RESOURCE The Department of Energy has defined Class 4 for the cost-shared oil recovery field demonstration program as strandplain/banier island reservoirs. This depositionally defied class of reservoirs represents a significant portion of the Nation's oil resource, as described in the DOE Tertiary O i l Recovery Information System (I'ORIS). The purpose of Chapter 2 is to present an overview of the reservoir, production, and geological characteristics of Class 4 reservoirs. Section 2.1 descriies the overall strandplain/banier island resource in the country based on an analysis of 330 Class 4 reservoirs listed in the TORIS database. Section 2.2 describes the general geological characteristics of strandplai4barrier island reservoirs based on a comprehensive review of the relevant geological literature. Section 2.3 presents an overview of the major Class 4 plays in the United States and includes summaries of the resource, reservoir, and production characteristics, as well as a summary of the recovery processes that have been used in these plays. The major plays are described in detail in Chapters 3 through 6. This facies, dong with the often overlying eolian facies, discussed below, constitutes the best reservoir rock associated with strandplainbarrier island systems.

“…The Rose Run sandstone would represent Class 4, strandplain/ barrier island reservoirs, in the DOE geological classification (Cole et al 1994). The Rose Run sandstones were deposited as lowstand deposits during third-order sea level falls and reworked during subsequent highstands of sea level (Read 1989).…”
