WebHigh-quality three-dimensional (3D) seismic data acquired in the central Sichuan Basin, southwestern China, offer an opportunity to map complex lithologies in a mixed siliciclastic-carbonate-evaporit WebWe allow it to vary between −90° and +90°, which gives an extension of EI for any combination of intercept and gradient. We refer to this form of elastic impedance as extended elastic impedance (EEI). In this paper we demonstrate that EEI can be tuned using different χ values to be approximately proportional to a number of elastic ...

WebLithology voxels are displayed in the 3D Viewer . Using the 3D Tool functions, you can manipulate the display of the voxel, such as selecting individual or multiple "lithology" units for display, data extents, transparency, etc. This How-To Guide walks you through the recommended workflow for creating a lithology voxel, as outlined below: 1. Webreferred to as slowness, is the reciprocal of velocity. Lithology and porosity affect ∆t. Dense, consolidated formations characterized by compaction at depth generally result in a faster (shorter) t while fluid-filled porosity ∆ results in a slower (longer) ∆t. Measurements are also uniquely affected by formation and borehole conditions.
