An imaging journey over Stampede field, Gulf of Mexico: improvements and challenges

摘要

Stampede field, formerly known as Pony-Knotty Head field, is a sub-salt Miocene discovery in the deepwater, Gulf of Mexico. Although it is a well imaged structure, development and production requirements warranted an improved image over the field. From the discovery through field, development, a variety of seismic data such as NAz (Narrow Azimuth), WAz (Wide Azimuth) and Dual Coil (Full Azimuth or FAz) have been used to meet these requirements. In this paper, we are going to present improvements in imaging at the Stampede field over time and discuss issues and challenges in sub-salt imaging in general.
