Because onshore 3-D surveys can be expensive, the results may not be considered cost-effective. This case history presents an onshore 3-D survey that was cost-effective and that shows the power of 3-D seismic versus well control and 2-D data.
Discovered in 1945, the Dollarhide field is a large faulted anticline in Andrews County which is located on the Central Basin Platform of west Texas. Production in this field is from the Permian Clearfork, Devonian Thirty-one, Silurian Wristen, and Ordovician Ellenburger formations. (The commonly used names for the reservoirs are in italics.) Well spacing is approximately 40 acres (16 ha) and the Devonian formation is currently undergoing CO2 flooding.

Interpretation of Three-Dimensional Seismic Data
This publication is the definitive, and now classic, text on the subject of interpretation of 3-D seismic data. Conceived in 1979 and first published in 1986, the book helps geoscientists extract more information from their seismic data and improve the quality of their interpretations.
