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

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

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
