Abstract (Summary)

The Horn Mountain and King fields are located in the northeastern portion of the Mississippi Canyon protraction area. These two deep-wateroil and gas fields have collectively produced approximately 200 MMBO, 220 BCF, and 50 MMBW. Using the Hampson-Russell software, fluid substitution was performed and forward models were generated for the productive sands found in these fields. The seismic data set used for this study was zero-phase, Kirchhoff pre-stack time migrated data from WesternGeco's Mississippi Canyon 13-Q 2002 seismic survey. Based on the modeling results of this study, it was apparent that differences in acoustic impedance provide significant discrimination between hydrocarbon-filled sands and swept sands.Freeport-McMoRan Oil and Gas recently acquired and is currently processing a time-lapse (4D) seismic survey, over the Horn Mountain and King fields. The results of this study show that time-lapse seismic should serve as an excellent tool to monitor fluid movement in both the Horn Mountain and King fields. Amplitude vs. offset (AVO) plots were also generated for the intervals of study, in which Horn Mountain Field displayed a Class III response and the King Field was characterized by a Class IV AVO response. These different AVO signatures were believed to be related to lateral variations in sand cementation and shale properties.
