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.
Web10 apr. 2024 · Logging data. The geological characteristics of the research area determine the complexity and heterogeneity of lithology. The data for this paper are from five boreholes in the study area and contain 13 different logs (including density, drilling liquid resistivity, natural gamma-ray, long source distance, short source distance, borehole … WebA common practice in log interpretation is to cross-plot various porosity log readings in order to determine formation lithology and compute porosity accurately. Crossplots of Sonic versus Density logs are widely used in the interpretation of shaly sands. For carbonates, Density versus Neutron cross-plots are commonly employed.
