| dc.description.abstract | Although Serbin Field in southeast Texas was discovered in 1987, lithological and petrophysical properties in the southeastern part of the field have not been fully evaluated. We generated instantaneous frequency from 3D seismic data and predicted gamma-ray response volume from seismic attributes. By extracting maps of instantaneous-frequency and gamma-ray response along interpreted horizons, and crossplotting instantaneous-frequency against gamma-ray logs and integrating core data, we generated lithology maps to identify shale-prone zones that stratigraphically trapped hydrocarbons in the southeastern part of the field. We demonstrate that Serbin Field is separated into two areas: (1) a high-frequency, high-gamma-ray, and high-acoustic-impedance area in the northwest; and (2) a low-frequency, low-gamma-ray, and low-acoustic-impedance area located in the southeast. By developing a lithologic map and relating it to the corresponding instantaneous-frequency map and log data, we also show that the southeastern part of the field can be divided into three zones: (1) Zone 1, composed of ~2–8 ft (~0.7–2.7 m)-thick sandstone-rich beds of moderate frequency (25–30 Hz); (2) Zone 2, composed of high-frequency (33–60 Hz) shale-rich zones that serve as stratigraphic-trapping mechanisms; and (3) Zone 3, composed of ~5–13 ft (~1.7–4 m)-thick sandstone-rich beds of low frequency (0–18 Hz), and relatively high porosity. These methods can be applied in other areas of the field with limited well control. | |
