The Soldier Mound Tannehill & Stockwether Fields, Dickens County: Classic Examples of Two Major Eastern Shelf Play Types

Abstract

Soldier Mound was drilled as a Tannehill Shelf Margin Delta prospect resulting in a new field discovery in mid-2001. The prospect further exceeded expectations upon discovery of the first production from the Stockwether Limestone in the region.

The quality of production from Soldier Mound's two reservoirs stimulated a frenzy of activity for the next several years in southwest Dickens. This activity resulted in the discovery of 18 official new field discoveries in 29 distinct reservoirs over the next few years. When down dip, basinal reservoirs were correctly recognized as being equivalent to shelf deposits to the east and a common oil type was found throughout the system it became obvious there had to be traps in between. All of these new fields are within a now very noticeable gap in the Tannehill's 100 mile long productive trend.

This presentation will discuss regional concepts that led to identification of the play along with trap, reservoir and production characteristics of both reservoirs.
