Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This study aims to characterize the reservoir properties of the West Waha and Worsham-Bayer fields in the Southeastern Delaware Basin, West Texas, to determine the impact of thin beds on reservoir petrophysical analysis and to assess the impact of estimated recoverable reserve on the interpreted reservoirs.

• Impact of thin-beds on reservoir petrophysical analysis
• Influence of estimated recoverable reserve on reservoir characteristics
• Structural evolution of the basin and its role in trapping hydrocarbons
• Relationship between structures and stratigraphy in the area
• Causes of low natural gas recovery in the fields

Zusammenfassung der Kapitel (Chapter Summaries)

Chapter One provides an introduction to the study, outlining the general statement, study location, statement of the problem, objectives, physiographic setting, scope and methodology, and previous work conducted in the area.

Chapter Two delves into the regional geology of Texas, starting with a generalized overview of the state's geology and specifically focusing on the geology of West Texas. It then provides a detailed exploration of the Delaware Basin, its geological history, and the geologic setting of the West Waha and Worsham-Bayer fields.

Chapter Three outlines the methodology used in the study. This includes the data volumes used, how the data was used, a summary of the data, the place of data interpretation, and a detailed description of the interpretation procedures for well log correlation, petrophysical parameters calculation, reservoir attributes, seismic-to-well ties, 3D seismic interpretation, structural framework mapping, time-depth structure maps, recoverable reserve estimation, and production record interpretation. It concludes with a statement on the limitations of the study.
