Abstract
A subsalt seismic image is challenged by complex salt bodies and poor illumination, in spite of great technology advances achieved in recent years. We developed an automated method referred to as Interpretation-Guided Image Enhancement (IGIE), to optimize and enhance the subsalt image by using Reverse Time Migration (RTM) Vector Image Partitions (VIPs). Starting from a few interpretation horizons, IGIE boosts signals from a specific shooting direction that illuminates the target events and suppresses noise from other directions. To demonstrate the effectiveness of our method, we present a case study from the Gulf of Mexico. The results show that IGIE successfully reveals steeply dipping subsalt events that are hidden under noise
