Seismic reflection is a geophysical method used to infer properties of the Earth's subsurface, and is often applied in hydrocarbon exploration. The field has advanced rapidly over the past several decades, and high quality 3-D seismic is currently a widely used exploration tool. While technology has improved markedly since the introduction of 3-D seismic in the late 1970's, numerous difficulties still arise when mapping subsurface features. Seismic attribute analysis can be used to extract additional information from such datasets to assist in the geologic interpretation process. This project will involve the study of seismic attributes derived from a 3-D seismic dataset over Yougeen Field in Bee County, Texas to study the Yegua formation. These attributes include Similarity, Instantaneous Frequency, Sweetness, and Spectral Decomposition. The Yegua formation is a known hydrocarbon reservoir, and by coupling these attributes with well logs and production data, I hope to better understand the relationship between seismic attributes and existing hydrocarbon production. In addition, I hope to resolve subtle geologic features within the formation that are not visible in the original amplitude data.
