Addressing challenges in deep water Gulf of Mexico depth imaging through geologic models and acquisition simulation — The Tempest Project

Abstract

This paper describes the framework for constructing a realistic deep water Gulf of Mexico geologic model, marine acquisition simulation using full offset wave equation, application of various depth migration tests using the known model, and comparison of the model data results to real data results. The main focus of our project was to construct a realistic geological model, to simulate seismic acquisition using typical marine acquisition geometry and parameters and to image the data using prestack depth migration algorithms that are used in routine production processing. The project results are a series of prestack depth migrated volumes generated using various Kirchhoff and wave equation algorithms. These volumes serve as an interpretation guide and aid our understanding of complex salt bodies and subsalt structures in real deep water Gulf of Mexico datasets.

Application of artificial neural networks for compounding multiple damage indices in Lamb-wave-based damage detection

“…Recent developments in the area of GPUs have demonstrated that new architectures available in low‐cost graphical cards, called Compute Unified Device Architecture (CUDA), can be efficiently used for numerical simulations. The CUDA technology has been used to develop extremely efficient and accurate modeling tools in medicine, finance, seismology, and computer‐aided design, as shown in .…”

“…Besides complexity of simulating wave propagation in that media, different studies proved that strong velocity contrast of some geological units (like salt and anhydrate) with surrounding media is another great challenge for most of the seismic imaging algorithms and interoperation techniques (Albertin et al 2001;Ray et al 2004;Seitchick et al 2009). Examples of such settings are Gulf of Mexico, Avon canyon in Benin (Dahomey) basin (Olabode and Adekoya 2008), Jeffara basin in southeastern Tunisia (Gabtni et al 2012) and Qiangtang terrane, Tibetan plateau (Lu et al 2009).…”
