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 ... 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.
WebThe lithology of this porphyritic basalt is characterized by olivine and augite phenocrysts. The texture of a rock describes the relationship between the individual grains or clasts … WebLithologic fractions of total clay, total carbonate, and QFM (quartz, feldspar, and mica) are derived from the concen- trations of silicon, calcium, and iron. Matrix density is calculated from silicon, calcium, iron, and sulfur, and it is com- bined with the measured bulk density to derive an accurate total porosity.
