Nickzom Calculator Solves Porosity in Sonic Log under Geology – The Calculator Encyclopedia

Last Updated on February 8, 2024

According to Wikipedia, Sonic logging is a well logging tool that provides a formation’s interval transit time, designated as , which is a measure of a formation’s capacity to transmit seismic waves. Geologically, this capacity varies with lithology and rock textures, most notably decreasing with an increasing effective porosity. One may wonder if there’s a calculator for Geologists that can easily solve calculations on porosity for sonic log. Yes, there’s a simple tool to use to fast-track the process.

Nickzom Calculator+ (Professional Version) – The Calculator Encyclopedia solves calculations on porosity for sonic log and shows the steps carefully.

The parameters to input to get the answer for your porosity problem are:

  • Internal Transit Time of Formation
  • Internal Transit Time of Matrix
  • Internal Transit Time of the Fluid in the Well Bore
  • Compaction Factor

Wylie Time-Average Equation

Many relationships between travel time and porosity have been proposed. The most commonly accepted is the Wyllie time-average equation. The equation basically holds that the total travel time recorded on the log is the sum of the time the sonic wave spends traveling the solid part of the rock, called the rock matrix, and the time spent traveling through the fluids in the pores.
