... with the true geological model. We explore how the attributes’ parametrization affects the imaging of differently sized features by modifying the analysis window in each case from +/-2ms to +/- 100 ms. Results show that the “mixing” occurs as a result of 1) the seismic bandwidth, 2) the algorithm used for each...

... In this paper, we demonstrate a workflow to detect channel reservoir quality within a pro-glacial channel system. The workflow is based on training a 2D UNET network on a realistic 3D geological model conditioned by the facies at the wells. The goal is to simulate the facies distribution...

... of salt and subsalt seismic events. Identifying and removing them is crucial for optimal seismic imaging of subsalt targets. We propose a method to model these noises using a geological model and elastic finite-difference forward modeling. The method requires that the shallow part of the geological model...

... are often processed differently, misties are frequently observed between the lines, which may lead to cumbersome interpretation. In this paper, we introduce a method aiming at providing an efficient 2D line seismic interpretation answering the need of obtaining early 3D geological model during reservoir...

... built a 3D high-resolution volume of shale (Vshale) model with random stratigraphy constrained by well log statistics. Realistic rock properties were generated as a function of sand, shale, and fluid saturation and were embedded in this stratigraphic model. With this geological model, we generated 2D/3D...

The seismic forward modeling of geological model is the commonly used technology for us to reveal the lateral and vertical response characteristics...

... ABSTRACT In order to develop an appropriate model for long-term research efforts in seismic wave propagation through a complex near-surface, we built a geological model on an ultra-fine grid of a field area in Alaska. A rock physics and solid substitution workflow was used to calculate seismic...

... Summary Despite the important increase of the computational power in the last decades, simulating the seismic wave propagation through realistic geological models is still a challenge. By realistic models we here mean 3D media in which a broad variety of heterogeneities lies, including...
