WebPorosity from the Sonic Log The sonic log is widely used to estimate porosity. The method works well when shale volume and matrix rock sonic travel time are accurately known. … WebJul 28, 2016 · The sonic log may be used to determine porosity by charting the speed of a compressional sound wave as it travels through the formation. Interval transit time (∆t), measured in microseconds per meter [foot] and often referred to as slowness, is the reciprocal of velocity. Lithology and porosity affect ∆t. full metal armory haubstadt

WebThe sonic log will underestimate porosity in uncompacted formations. In general, the sonic log is unsuitable for these formations and should not be used to determine porosities. However, if only the sonic log has been run, then it is possible to correct for this underestimation, an empirical correction factor, C p, is used, as follows: ∅= WebNov 15, 2024 · sonic log / Acoustic logging is one of petrophysical tool to evaluate well parameter oil filed Abdullah Abderahman Follow Advertisement Advertisement Recommended Sonic log Zubair Kamboh 12.7k views • 44 slides Acoustic Logging Priyansh Bhimajiyani 540 views • 25 slides Presentation on sonic log Asrar Hussain 1k views • 17 … WebDec 4, 2024 · Figure 6: Sonic Logs and Seismic Ties Array sonic logs were developed to provide information about a variety of acoustic properties such as porosity, permeability, … ginger\u0027s divine ice creams
